CUBAN SUBFAMILY CHONDROPOMINAE TORRE AND BARTSCH 211 



spiral bands of darker brown, which are intensified in definite axial 

 reo-ions to form almost a varicial element. There is also a darker 

 zone of brown a little behind the peristome, the latter being yellowish 



white. 



The type, U.S.N.M. no. 428789, is a perfect specimen having 6.2 

 •whorls and measnring : Length, 23.7 mm ; greater diameter, 23.6 mm ; 

 lesser diameter, 17.0 mm. 



CHONDROPOMETES (CHONDROPOMETES) VIGNALENSE POENITENTIS, new subspecies 



Platk 7, Figure 3 



This subspecies resembles C. {C.) vignalense, hrimeocincfum but is 

 considerably smaller and usually has a decidedly purplish tinge. It 

 appears to range from the mogotes Dos Hermanos to Cuajani to La 

 Penitencia. 



The type, U.S.N.M. no. 468701, was collected at the Cafetal de la 

 Penitencia. The type is a complete specimen, having 6.0 whorls 

 and measuring : Length, 20.0 mm ; greater diameter, 20.0 mm ; lesser 

 diameter, 15.9 mm. 



CHONDROPOMETES (CHONDROPOMETES) VIGNALENSE INFERNALE, new subspecies 



Plate 8, Figure 7 



This exceedingly delicate shell is semitranslucent, of pale brown 

 color, and marked by slender spiral bands, which are almost continu- 

 ous on the last whorl. The peristome is pale orange. 



The type. U.S.N.M. no. 367731, was collected by Father Koca at 

 Sitio dei Infierno, southwest of Vinales. It has a little more than 3 

 wliorls remaining and measures: Length, 21.0 mm; greater diameter, 

 21.9 mm ; lesser diameter, 15.3 mm. 



CHONDROPOMETES (CHONDROPOMETES) VIGNALENSE PALMARITENSE, new 



subspecies 



Plate 8, Figure 5 



Shell pale brown with a decidedly darker axial zone a little behind 

 the peristome, which is white. It is obscurely interruptedly spirally 

 banded. These marlvings, however, have to be looked for or they 

 will be overlooked on account of their faintness. 



This subspecies, wdiile resembling C. {€.) vignaleme hrimeocinc- 

 turn^ is readily distinguished from that by its decidedly smaller size 

 and fainter spiral markings. 



The type, XJ.S.N.M. no. 428791, w^as collected by Bartsch on Mogote 

 Palmarito. It has 3.5 whorls remaining and measures: Length, 

 16.8 mm; greater diameter, 19.2 mm; lesser diameter, 14.0 mm.
