spicuous they are narrower than the spaces that separate them, in which 

 respect it differs from Chondropoma (Chondropomium) swiftii satu- 

 ratuni, in which the reverse holds true. It is also much larger than that 

 race. 



The type (U.S.N.M. No. 354956) has 4.3 whorls remaining and

This race occupies the lowlands bordering Lake Assuei, sometimes 

 called Lake Saumatre, extending east to Fond Parisien on the south 

 shore of Lake Saumatre, while on the north of the lakes it extends east- 

 ward to a little beyond Lake Enriquillo. 



The truncated shell is of ovate outline; the ground color flesh-colored 

 with just a mere touch of yellow. There are interrupted spiral bands 

 of brown, and on the early postnuclear whorls there is a zone of brown 

 immediately anterior to the suture. This is the largest subspecies. 



The specimen figured (U.S.N.M. No. 354950 was collected by Salle
