Haitian Species. 

 8. V. INOPINATA Pilsbry, n. sp. PL 15, figs. 6, 7. 



This species is known by three incomplete individuals: a 

 young shell of 5 whorls, 3 mm. long (fig. 6), a nearly adult 

 shell which has lost the early whorls, the part remaining 

 6 mm. long, 2.1 wide (fig. 7), and an immature shell of 6 l /z 

 whorls, 4.7 mm. long. 



The first half whorl is smooth ; next whorl set with straight 

 and rather widely spaced delicate ribs, which gradually be- 

 come much closer on the last embryonic whorl. There are 

 2% whorls in the embryonic shell, which is somewhat cylin- 

 dric, and .8 mm. in diameter at the last whorL The sculp- 

 ture then abruptly changes to the adult type. The earlier 

 post-embryonic whorls are convex ; the later ones are flattened 

 peripherally, being obtusely biangular. Sculpture of slightly 

 irregular, widely spaced ribs, which are more prominent 

 where they pass over the angles at shoulder and base of each 

 whorl. There are 14 ribs on the last, 15 on penult whorl. 

 The intervals are closely sculptured with very low rounded 

 spiral cords and a few unequal, in part subobsolete vertical 

 striae. 



Haiti: Cape Haitian (J. B. Henderson). 



This species seems to be closely related to V. acuticostata 

 of Western Cuba. It has a narrower and shorter embryonic 

 shell, of a half-whorl less, and there are more ribs on the 

 later whorls. I have not been able to compare it with the 

 East Cuban V. tuberculata, which from the imperfect de- 

 scription seems to be different, though closely related. A
