BULINUS. 173 



c. BULINUS NITENS, PMiijpi? 



Plate 7, fig. 15. 



I have figured a shell found at Vera Cruz, 

 which may be the above species, not entirely 

 mature. The original figure of 7iite7is, which 

 is accurately copied in Binney's work, f. 168, 

 appears to be drawn from an abnormal speci- 

 men. 



Subfamily POMPHOLINJE, Dall. 



Shell depressed, few-whorled, the last whorl 

 the largest, without fold on the columella. 

 Inoperculate. Animal, foot rounded, tentacles 

 long, eyes situated at the outer bases of the 

 tentacles.
