Types : Academy of Natural Sciences, Philadelphia, No. 85455. 



Type Locality : Barbadoes. 



Animal, Jaw and Genitalia : Not examined. 



Range : West Indies. As this race has been confounded with 

 cubensis it is impossible, without an examination of specimens, to sepa- 

 rate the two forms in the records from Cuba. Aspirans probably in- 

 habits a number of the West Indian Islands. 



RECORDS. 



Barbadoes: Barbadoes (L. B. Brown ; Walker). 



St. Croix: St. Croix (I. I. Brown). 



Geological Range : Unknown. 



Ecology : Not recorded. 



Remarks : Aspirans may at once be distinguished from cubensis 

 by the form of the inner lip which is narrow and stands erect, while 

 in cubensis the inner lip is more triangular arid is rolled over toward 

 the umbilical chink. The shell in aspirans is more uniformly ovate as 

 is also the aperture. The shell is also larger than cubensis, the spire is 

 usually longer, the whorls are rounder and the umbilical chink is 

 usually more conspicuous. It has heretofore been called cubensis, but 

 the characters outlined above seem sufficient to distinguish it as a race.
