CUBAN SUBFAMILY CHONDROPOMINAE — TORRE AND BARTSCH 349 



are much more conic in outline, much less strongly crenulated at the 

 summit, and much darker, with the peristome yellow. The sculpture 

 is also liner than C. (0.) carenasense toroense and more regular. 



The type, U.S.N.M, no. 499613, is a complete specimen of 7.5 whorls 

 and measures: Length, 15.2 mm; greater diameter, 7.7 mm; lesser 

 diameter, 6.2 mm. 



CHONDROPOMA (CHONDROPOMA) CARENASENSE GUAURABOENSE, new subspecies 



Plate 32, Fiquke 5 



This is a small race of yellow or buff color, except the peristome, 

 which is white. The interrupted spiral bands are inconspicuous, 

 and the sculpture is much more closely spaced than in C. {C.) care- 

 nasense carendsense. 



The type, U.S.N.M. no. 104488, has almost 4 whorls remaining and 

 measures: Length, 9.3 mm; greater diameter, 5.6 mm; lesser diam- 

 eter, 4.5 mm. It comes from Boca de Guaurabo. 



CHONDROPOMA (CHONDROPOMA) CARENASENSE ROSARIENSE, new subspecies 



Plate 32, Figure 6 



This race comes from Kosario about 15 miles west of Cabeza del 

 Toro. It is exceedingly variable in size. Specimens even slenderer 

 than C. (C.) carenasense guaurahoense may be found, and from this 

 they increase in size to half that of C. (C.) carenasense carenasoise. 

 Like carenasense the sculpture is sharply cusped. 



The type. U.S.N.M. no. 493160, has 5 whorls remaining and meas- 

 ures: Length, 12.0 mm; greater diameter, 6.1 mm; lesser diameter, 

 5.5 mm. 



A complete specimen of 7.1 whorls, on the other hand, measures 

 only: Length, 11.5 mm; greater diameter, 5.3 mm; lesser diameter, 

 4.4 mm. 



CHONDROPOMA (CHONDROPOMA) CARENASENSE CANTILLENSE, new subspecies 



Plate 32, Figure 7 



This race was collected by Bartsch on Cayo Cantilles east of the 

 Isle of Pines. It equals in size the average of G . (C.) carenasense 

 Tosariense but is much more yellowish, with yellow peristome and 

 with much finer and more numerous axial and spiral sculptural 

 elements. 



The type, U.S.N.M. no. 499614, has a little more than 4 whorls 

 remaining and measures: Length, 11.5 mm; greater diameter, 5.9 

 mm: lesser diameter, 5.4 mm.
