Bulimulus serperastrus, Say. 

 multilineatus, Say. 

 Dormani, W. G. B. 



Bulimulus Floridanus, Pfeiffer. 



I have already in Terr. Moll., IV., Plate LXXIX. Fig. 3, figured the front 

 view of the typical specimen in Mr. Cumings's collection, drawn by Mr. G. B. 

 Sowerby. The back view is now offered (Plate III. Fig. 7), received from the 

 same source. 



A comparison of the front view of Mr. Sowerby's drawing referred to above, 

 with the figure of Bulimulus Hemphilli (Plate III. Fig. 9), recently received 

 from Mr. George W. Webster, will lead one to believe the 

 two to be identical. I so suggested in Manual of American 

 Land Shells (p. 408), when treating the variegated shell fig- 

 ured in Fig. 449 of that work, here repeated. There appear 

 to be two varieties of coloring, one corresponding to Pfeiffer's 

 description, and one to Sowerby's figure. 



I give the description of B. Hemphilli in full, though I be- Bulimulus 

 lieve it to be identical with Floridanus. 



Shell imperforate, very thin, transparent, amber-colored and marked by coarse 

 lines of growth ; body whorl with six revolving and slightly interrupted brownish 

 red bands, the lower two being close together and upon the rounded base, spire 

 obtuse, whorls five, slightly convex, the body whorl constituting two thirds of the 

 entire length of the shell. Suture slight, base uniformly and gracefully rounded. 

 Aperture direct and oval, peristome thin. Length, 19 mm. ; diameter, 8 mm. 

 Hab. both coasts of South Florida. 



Remarks. Mr. Henry Hemphill, of San Diego, Cal., first found a few dead 

 and badly preserved specimens of this shell in 1884, at Marco, west coast of 

 Florida. These Mr. Binney thought identical with B. Floridanus, Pf. (See Manual 

 of American Land Shells, 1885.) Numerous specimens collected during the past 

 summer by the author and Mr. G. W. Webster and son, prove beyond a doubt 

 that this is not identical with the shell figured and described on page 407 of Mr. 

 Binney's Manual. The B. Hemphilli is more ventricose, not angular at base, im- 

 perforate, differs in color, and in fact there is a general difference. 



Mr. Berlin H. Wright describes the above species in the West American 

 Scientist, San Diego, April, 1889, p. 8. He found also a variety of uniform 

 light brown or russet color, bandless, which I have figured on Plate III. Fig. 9. 

 This form had a jaw and lingual membrane the same as in B. Maridinus 

 and Dormani 



Bulimulus Marielinus, Poet. 

 Cylindrella Poeyana, D'Orbigny.
