CHONDROPOMETES (CHONDROPOMETES) VIGNALENSE CLAPPI, new subspecies 



Plate 7, Figure 11 



This delicate, thin-shelled, translucent, ground-glass white race 

 comes from the north end of the Sierra de la Chorrera. We gathered 

 more than 100 specimens about the cave from which a small stream 

 issues. 



The type, U.S.N.M. no. 428786, is a complete specimen having 6 

 whorls and measuring: Length, 22.4 mm; greater diameter, 22.0 mm; 

 lesser diameter, 16.0 mm. It is named for Dr. George Clapp, who was 

 a member of the Tomas Barrera Expedition when we obtained most of 

 our specimens.

Wright, in his travels through western Cuba, was the first to make 

 known this species, and he distributed his material under the general 

 label "Vinales." We know from various other species collected by 

 Wright that he gathered material about the southeast end of the Sierra 

 de la Chorrera, and recent collecting here has produced material that 

 is in every way comparable with the specimens in our collection re- 

 ceived from Wright. It seems proper, therefore, that the race occu-
