AE NAUTILUS.

Vol. SXxXTTI JULY, 1919 No. 1.

AN OLD COLLECTING GROUND REVISITED.

BY CHARLES W. JOHNSON.

While a resident of St. Augustine, Florida, from 1880-88, I made a careful study of the mollusca of the harbor and vicinity. The habits of the various species and the factors governing their distribution, which in many cases was much restricted, especi- ally appealed to me. With these facts in mind it was with great interest that I visited the old city after an absence of thirty-one years. Time and the ever-shifting sands have played sad havoc with many of my old collecting grounds, and I looked in vain for some of the rarer species.

The accompanying maps can give only a general idea of the changes that have taken place.’ The ‘‘ Lagoon”? of the eighties is gone and there are now two inlets with about the same depth of water on each bar according to the government chart, survey of 1910, although I was told that the southern channel has now much less water on the bar than the other. Marsh Island at the mouth of Hospital Creek is also gone, and the sand bar that was formerly only east of the island now extends to the fort. There is no trace of the site of the old Spanish lighthouse,

1Figure 1 shows the harbor and vicinity about 1883, before the St. Sebas- tian marsh was filled, also the approximate positions of the ‘‘ Lagoon’’ and Marsh Island. The figures refer to the species mentioned in the text that were found at those particular places.

Figure 2 is based on the U. S. coast survey chart, No. 159, survey of - 1910, and represents in a general way present conditions.

which was probably at the extreme end of the now exposed ledge of coquina and about 200 feet below the present high-

ing four jetties, one below and three above the ledge referred to, but the erosion apparently still continues. The following notes are based chiefly on those species that were very limited in their distribution and which therefore may have become locally extirpated by the many changes affecting their environ- ments. A list of about 200 species published by the writer in 1890* forms the basis of some of the following remarks.

Macrocallista nimbosa Sol. (1) This is the Callista gigantea Gmel. of my list. It was found only in the shoal water at the head of the ‘‘ Lagoon,’’ seeming to prefer the quiet water, as I never found a trace of it on the ocean beach. At most only six or eight specimens were found, and many of these were broken, probably by the large ray or ‘‘clam cracker’’ as the butterfly ray (Pteroplatea maclura) is called by the fishermen.

Donazx obesa d’Orb. (2) This little chunky species was formerly common on the sand bars at the mouth of the ‘* Lagoon,’’ where there was a slight shifting of the sand at every tide. The larger species, Donax variabilis Say, was (and probably is) exceedingly abundant on the ocean beaches, especially the ‘‘South beach.’’ I was quite amused at Day- tona to hear the popular name of ‘‘coquina’’ applied to this shell, and one young man talking about ‘‘coquina bouillon.”’ While this is entirely proper, as the Spanish word coquina means, broadly speaking, shell-fish, the name has become so generally used for the shell-rock (often made up largely of this species) that at first it sounded like pretty hard diet. JI am sorry that opportunity did not permit my getting a large series of this species including the young, as I should have liked to have made some comparisons of the young of D. variabilis with that of the typical or more northern D. fossor Say. As I re- member I could never satisfactorily separate the two forms at St. Augustine and omitted the latter from my list, although it is recorded from the entire coast of Florida and westward to Texas. Mazyck in his ‘‘ Catalog of Mollusca of South Caro- lina,’’ says of D. fossor, ‘‘ very rare, Sullivan Island.”’

THE NAUTILUS. 5

On one visit to the South beach I found it literally strewn with perfect specimens of Dvivaricella quadrisulcata d’Orb. (Lucina dentata of my list), but never again did I find them in such numbers. At another time quantities of an Arca referred to in my list as Arca americana Gray, were found. It is more elongated than those found in the harbor, with a thinner and lighter brown periostracum, and probably represents only a variety or ocean form of A. campechiensis Dillw. (Arca pexata Say).

Lucina philippiana Reeve (Loripes edentula of my list). Large single valves were frequently found and occasionally at the mouth of Hospital creek shells were found in the mud with both valves intact, but like the Phacoides filosa Conr. in Portland harbor, Maine, always dead. It may also be of interest to note that two specimens of Solemya velum Say, and a few single valves of Mya arenaria were found on the north beach, the most southern records for the species.

Panopea bitruncata Conr. (5) This large and variable shell which was referred to in my list under both Glycimeris reflexa Say, and G. americana Conr., was later the subject of a paper by the writer’ in which the synonymy was straightened out, and a fine specimen found on the bar east of Marsh island was figured. Common in the pliocene of the Caloosahatchie, but recent examples are exceedingly rare. Living deep in the mud they are difficult to obtain, unless on rare occasions extensive harbor dredgings might bring some to the surface. They are also very apt to be destroyed by changes such as encroaching sand bars, sedimentary deposits, and harbor pollution.

The rocks that represented the ruins of the old Spanish lighthouse (the tower of which fell in June, 1880, while the keeper’s house had fallen several years before) were a favorite place for Thais floridana Conr. (Purpura haemostoma var. floridana of my list). During my recent visit I failed to find a living specimen of this species either on the ledge or jetties, but the tides were not very low and it may be that they could have been found at a lower tide. On all of the rocks including the

6 THE NAUTILUS.

jetties were great numbers of Siphonaria naufragum Stearns (S. lineolata d’Orb.). One thing that seemed to impress me more than when I lived there, was the great abundance of oysters on all the rocks, even around the water battery of the fort and also on the piling. In speaking to an old friend regarding the matter, he said he thought that around the fort it was due to cleaning off the rocks a few years ago, thus presenting a clean surface for the young to cling to. This array of bristling oysters around the water battery of the fort deterred me from a hunt for Nerita peloronta and N, versicolor (5), three living speci- mens of which I found there together with Litorina angulifera, being the most northern record for the three species.

Cerithidea scalariformis Say (6). The only place that I ever found this species at St. Augustine was in the more sandy por- tion of the marsh west of the city between King street and Orange street, not far from where the Y. M. C. A. building now stands. The filling-in of the marsh has probably locally ex- tirpated this species. Another related species Cerithium flori- danum Morch (7), C. atratum of my list, was also restricted to a small area, an old oyster bed at the west end of Marsh island. This is now a sand bar and the species may now be entirely absent in the harbor. At the latter place I also found my only living example of Murex fulvescens Sowb. (M. spini- costata Val.).

At the mouth of Hospital creek was a large patch of the grass-like Gorgonia—Leptogorgia virgulata. On this lived the little Simnia uniplicata Sowb. 8 (Ovula uniplicata), as the Gor- gonia varied in color so did the shells of the Simnia, agreeing in color with the bunch of Gorgonia on which they were found— either white, light-yellow, orange or pink. On one occasion while hunting for Simnia a conspicuous object attracted my at- tention, its flesh-colored mantle with irregular blackish mark- ings was very striking, and as it contracted I found I hada Cyphoma gibbosa Linn. (Ovula gibbosa), common to the West Indies. For some time I wondered why the animal of this shell should be so very conspicuous; then the thought occurred to me that in more southern waters probably most of them live on the ‘‘sea-fans’’ (Rhipidogorgia flabellum) and with their

THE NAUTILUS. i

reticulated structure as a background the animals would be scarcely distinguishable, like the Sargassum fish (Pterophryne histrio) in the gulf-weed (Sargassum).

Cyrena carolinensis Bosc. (9). In making a bridge across a small branch of the St. Sebastian River I first discovered this species. It was a large and interesting variety in which the umbones were unusually high, many of the specimens closely resembling in size and form the figure of C. olivacea Carp. from Mexico, as given by Prime (Monograph American Corbiculidae, p. 17, fig. 12, 1865). Although the tide flowed freely up the little creek, there was at low tide a small stream of fresh water even at the driest time. At the junction of this little stream and the high ground there was a small colony of Neritina lin- eolata Lam. (JN. reclivata Say). I looked in vain for this species during my recent visit, nor did I find Cyrena near the little bridge, but it may still exist in other parts of the stream which time did not permit me to examine thoroughly. At the mouth of Pellican creek near the Matanzas Inlet was a colony of Neritina virginea Linn. They were the olive-green or more brackish water type and probably represent the most northern limit of this species on the Atlantic coast. About seven miles south of Matanzas Inlet was a large cypress swamp in what was known as ‘‘ Bike’s Hammock,’’ here was found Ampullaria depressa var. hopetonensis Lea, which seems quite distinct from those of the St. Johns River drainage. There were also fine specimens of Ancylus peninsulae Pils. & Johns.—erro- neously referred to A. filosus in my list. The east coast canal has drained much of this section now called Bikes Prairie on the coast survey chart. In many places I saw truck arms as I passed through the canal on my way north from Daytona.

These notes suffice to show some of the changes that can take place in a limited area in a comparatively short time, and the probable effect of such changes on certain species. It is not at all peculiar to St. Augustine, for similar changes are going on at many other places along the coast and in the vicinity of our cities. The importance of a careful study of a local fauna can- not be too strongly urged. The destruction of the forests, the

draining and filling of swamps and marshes, the construction of dams, etc., all tend toward lessening the fauna and flora of a given area. .

NEW LAND SHELLS FROM ALABAMA AND TENNESSEE.

BY GEO. H. CLAPP.

PoLITA CUMBERLANDIANA, Nl. sp.

Shell widely umbilicated, flattened, very slightly convex above and below, glossy, thin and translucent, light horn color, regularly but lightly sculptured across the whorls by curved, closely set radiating impressed lines parallel with the lines of growth which are very faint; spire flattened; stature shallow; whorls about 4, rapidly increasing, the last decending at the aperture which is elongate-oval flattened above, lip very slight- ly reflected at the columellar insertion; umbilicus wide, display- ing all the whorls and contained about 4 times in the diameter of the shell.

Greater diameter 8, lesser 2.5, altitude 1.25 mm.

Collected by Herbert H. Smith on the Cumberland Plateau near Stevenson, Jackson Co., Alabama, also near Anderson, and near Sherwood, Franklin Co., Tennessee.

Types No. 9157 of my collection. Paratypes in the collec- tions of the Academy of Nat. Sci., Philadelphia and Bryant Walker, Detroit, Mich.

At first glance this species may be taken for immature V. radiatula as the general shape and the sculpture of impressed radiating lines are the same, but it is uniformly small with the same number of whorls, the sculpture is weaker and the shell more flattened. Under high magnification there is merely the faintest trace of impressed spiral sculpture. It is much smaller than Polita rhoadst.

Polita cumberlandiana: upper three figures. Vitrea pilsbryana: lower five figures, two at the right being immature shells, to show teeth of the neanic stage.

VITREA (PARAVITREA) PILSBRYANA, D. 8p.

Shell widely umbilicate, elevated, convex above, flattened be- low, thin, translucent, highly polished when immature but be- coming more opaque and yellowish in adults, light horn color, sculptured with unequally spaced radial grooves stopping at the periphery which is rather high; suture well impressed; whorls about 8 very closely coiled and slowly increasing, the last flat- tened above and below; lip simple very slightly reflected where it joins the columella, ends united by a thin callus; umbilicus wide, contained a little more than 3 times in the diameter of the shell, and showing all of the apex.

There are 3 or 4 pairs of large, tubercular, sometimes slightly oval teeth, visible thru the base of the shell at all stages of growth and in immature shells the upper teeth are visible from above. Theupper teeth, which are slightly below the periphery, are the larger, more elevated and round at thetop. The lower teeth are about centrally located on the base and are flattened

on top. When four pairs of teeth are present they are equally spaced at intervals of 90° and this appears to be the normal arrangement as only a few shells show three pairs which are spaced from 100° to120°. The single fully adult shell (figured) appears to have but 2 pairs of teeth, but the shell is a dead one and quite opaque. Two young shells, 1.5 mm diameter with 3.5 whorls and 2.5 mm. diameter, with 4.5 whorls, each have 3 pairs of teeth.

Greater diameter 5, lesser 4.5, altitude 2 mm.

Collected by Herbert H. Smith in a ‘‘Cove’’ on the Cumber- land Plateau, 3 miles north of Anderson, Franklin Co., Tenn.

Types No. 9159 of my collection. Paratypes in the collections of the Academy of Nat. Sci., Philadelphia, and Bryant Walker, Detroit, Mich.

This species belongs to the same group as V. capsella lacteodens and V. andrewse. It differs from both by the smaller size and wider umbilicus and from andrewse by the tubercular teeth arranged in pairs.

I name this species after Dr. H. A. Pilsbry whose ‘‘Revision of Paravitrea’’, Proc. Acad. Nat. Sci., 1903, pp. 204-212, Pls. X, XI, has done much to clear up this most interesting group.

A NEW FORM OF AMPULLARIA.

BY WILLIAM HEALEY DALL.

AMPULLARIA (FELIPPONEA) NERITINIFORMIS 0D. 8p.

Shell solid, whitish or lurid purple under an olivaceous rather strong periostracum, frequently banded with four or five purple- black broad spiral bands which are most conspicuous on the white inside of the outer lip, the white interspaces being subequal; these bands however show but little on the exterior except at resting stages, in the specimens examined; the form of the shell viewed from behind, strongly recalls that of Neritina reclivata or meleagris though with a rounded base; from in front it looks like a short spired heavy Campeloma. The nucleus is small and

blunt, always more or less eroded; there are about four whorls in the adult with indications of about five resting stages; the surface is smooth except for inconspicuous lines of growth; the young are somewhat naticoid, with a small umbilicus, but this shape rapidly changes; the whorls enlarge rapidly, being as it were appressed toward the suture which is distinct but not channeled, while the umbilicus becomes relatively larger and more or less funicular; the aperture is egg-ovate, entire, the posterior commissure solidly filled with callus, the outer lip internally thickened, patulous not reflected; the inner thickened, continuous over the body; height of shell 33; of last whorl 31; of aperture 23; maximum diameter (in front of the middle of the whorl) 26mm. U.S. Nat. Mus. Cat. No. 332780.

Habitat. Rio Uruguay, Department of Paysandu.

The operculum is horny, concentric, with the nucleus at the inner third; the radula is typically Ampullarioid and might be quite accurately represented by Troschel’s figure of the radula of A. urceus, in the ‘‘Gebiss der Schnecken.’’

The literature has been carefully searched, both on the lines of Ampullaria and Campeloma, but nothing of the sort has been discovered.

The subgenus is named in honor of Doctor Florentino Felip- pone, whose energy and interest in exploring the fauna of Uruguay are deserving of great praise.

The peculiar form of this species, and its funicular umbilicus, so different from that of any other in the genus, seem to authorize its separation.

A NEW SPECIES OF PHYSA FROM NEW YORK STATE.

BY FRANK C, BAKER.

PHYSA ONEIDA n. sp. Shell of medium size, ovate, slightly inflated; whorls about five, slowly increasing in diameter; spire short, broad, the whorls flattened; color yellowish-horn; surface smooth and shining, with rarely a trace of spiral striae, but the

lines of growth may form more or less marked raised lines in. some specimens; sutures slightly impressed, bordered below by a wide white band; protoconch smooth, rounded, rich wine color; aperture long-ovate, twice the length of the spire; peri- stome bordered within by a thickened rib edged with dark brown; columella thickened, slightly twisted; parietal wall covered by a thin callus which is folded over into and com- pletely closing the umbilical region.

Length, 15.0; width, 9.0; aperture length, 11.0; width, 5.0 mm. Paratype.

This Physa has been included under warreniana Lea by the writer for a number of years. It is a small edition of that species agreeing in outline with Lea’s figure and description in all essential details except size (see Lea’s Observations, xi, p. 120, pl. 24, fig. 81). Lea’s species, however, differs not only in size but has strong spiral lines on the surface which are ab- sent in oneida. The shell in the smaller species is also more swollen and less cylindrical, and the spire is more depressed than in warreniana. It resembles ancillaria and has been con- stantly associated by the writer with that species as a variety. The shell is not as broad as ancillaria and the whorls are not shouldered. It perhaps more nearly resembles Walker’s an- cillaria crassa, but differs constantly in being less solid, lacking the variceal bands, the body whorl is less swollen, the columella is not as heavy, the spire is higher, the outer lip is not as much arched, and the aperture is more elongate. The color of crassa is purplish-white with an opaque texture while oneida is yellowish-horn, polished, with a translucent texture. Hetero- stropha has a longer, more acute spire, a rounder aperture, somewhat shouldered whorls, and a more twisted columella. There is some variation in oneida in the height of the spire, im- mature specimens having a somewhat longer spire than mature

shells. The surface is usually destitute of spiral sculpture,

only a few faint impressions being observable in rare specimens.

One individual, however, had been injured when the body

whorl was about half completed and the part of the shell suc-

ceeding the injured portion is very heavily impressed with spiral lines, while the rest of the shell is perfectly smooth.

This shell was first recorded from Tomahawk Lake, Wis- consin, as Physa ancillaria warreniana. The same form occurs in Lake Maxinkuckee, Indiana, on the shore of Lake Michigan at Chicago, and a somewhat similar form has been received from Georgian Bay, Canada. It is the most abundant mollusk in Oneida Lake where it oceurs on a wave-beaten shore. It is probably widely distributed, and will be found in collections labeled ancillaria and heterostropha. Specimens that have sur- vived a second year and are of large size compare favorably with warreniana but may at once be separated by the absence of spiral sculpture which is especially strong in shells of Lea’s species from South Dakota and other western states.

NEW LAND SNAILS COLLECTED BY THE FERRISS AND HINKLEY EXPEDITIUN OF 1919.

BY H. A. PILSBRY AND JAS. H. FERRISS.

Sonorella montana. Resembling S. walkeri in form. Umbili- cus one-eighth to one-tenth the diameter. Embryonic whorls densely granulose with rather sparse protractive threads, the next whorl indistinctly granose, later whorls very smooth. Aperture large, the outer margin expanded, basal somewhat re- flected. Anatomically it is distinguished by the extremely short and slender penis, smaller than in any other species ex- amined.
