Types: Academy of Natural Sciences, Philadelphia, No. 85455. 
Tyre Locarity: 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. 
Barsapoes: Barbadoes (L. B. Brown ; Walker). . 
Di Ck0rs: St, Croix: (I. I, Brown): 
GEOLOGICAL RANGE: Unknown. 
Ecotocy: 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 and 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.
