Notes on Certain Terrestrial Mollusks. 85 



Stenogyra Dominicensis, Pfr. (Pseiiclobalea) . 



This was described in 1850 by Pfeiffer as a Balea, but in 

 1854 Shuttleworth (Diag. n. Moll. No. 6) referred it to titen- 

 ogyra. 



Pfeiffer described it as Bulimus hasta in Malak. Bl. 1856. 



From a Cuban specimen, in the Cabinet of R. Swift, I ob- 

 tained the animal and found it to be viviparous. From one 

 I took five embryonic shells, of from two to three whorls. 



The jaw and lingual membrane were examined by W. G. 

 Biuney, who informs me that they exhibit the characters pre- 

 vailing in Stenogyra, the jaw striate, without median projec- 

 tion ; central lingual tooth small, laterals large, subquadrate, 

 perfectly symmetrical in base of attachment and tricuspid. 



The jaw of S. decollata has the same fine stria?. 



Strophia calcarea, Pfr. 



Several dead specimens of this rather rare shell were col- 

 lected by Mr. D. Sargent on Little Inagua. The habitat of 

 the species has not hitherto been known. 



In a young shell (4 whorls), the umbilicus is 1J mill, in 

 diameter. The parietal tooth is shown in the figure in Chem. 

 ed. 2, t. 19, fig. 4, but not referred to in Pfeiffer's descrip- 

 tion. 



Strophia iostoma, Pfr. 



From Mr. Sargent I have remarkably fine specimens of this 

 species, from Turtle Cove, Great Inagua. The following 

 are measurements of extreme forms : 



13 whorls, Long. 46 lat. in med. 14 mill. 

 11£ " " 35 " 15 " 



11 " " 31 " 10 " 



Choanopoma occidentale, Pfr. 



Pfeiffer refers this species (Malak. Bl. 1860, p. 216) to 

 Martinique, but as M. Maz6 (1. c.) mentions, it does not ; 

 occur in that Island.
