 Plate 39, FiGxmE 6 



This race comes from Vita Harbor. It is a pale race, in which 

 the ground color is flesh-color, which renders the interrupted spiral 

 markings all the more conspicuous. It is also larger than the other 

 two races. 



The type, U.S.N.M. no. 468968, comes from the west side of Vita 

 Harbor. It has 3.3 whorls remaining and measures: Length, 11.6 

 mm; greater diameter, 7.3 mm; lesser diameter, 6.8 mm.

 Blatter, vol. 7, p. 30. 



The typical race comes from Baracoa. We also have it from 

 Cayojuin west of Baracoa. 



This race closely resembles that of C. (C.) soUdulum tanamense^ 

 from which it is differentiated by its uniformly larger size. 



The type, U.S.N.M. no. 493116, has a little more than 4 whorls 

 remaining and measures: Length, 10.4 mm; greater diameter, 5.8 

 mm ; lesser diameter, 5.2 mm.

 and Bartsch, Proc. U. S. Nat. Mus., vol. 58, p. 62 (nomen nudum). 



This race comes from Sagua de Tanamo. It resembles the typical 

 race in every way except in being much smaller. 



The type, U.S.N.M. no. 493122, has 3.5 whorls remaining and meas- 

 ures: Length, 8.8 mm; greater diameter, 6.3 mm; lesser diameter
