CUBAX SUBFAMILY CHONDROPORtlNAE — TORRE AND BARTSCH 389 



The type, U.S.N.M. no. 499606, one of a large series from the same 

 place, is almost a complete specimen. It has 7 whorls remaining 

 and measures: Length, 19.5 mm; greater diameter, 12.0 mm; lesser 

 diameter, 6.8 mm. 



CHONDROPOMA (CHONDROPOMARTES) IRRADIANS PANENSE, new subspecies 



Plate 36, Figure 4 



This, the largest race collected by Presas, Gundlach, Wright, Torre, 

 Henderson, Bartsch, and others on the south exposure of Pan de 

 Mantanzas, is comparatively dull in color and less strongly sculp- 

 tured tlian the rest. 



The type, U.S.N.M. no. 493133, has 5 whorls remaining and 

 measures: Length, 18.9 mm; greater diameter, 13.8 mm; lesser di- 

 ameter, 8.1 mm. 



CHONDROPOMA (CHONDROPOMARTES) IRRADIANS PALENQUENSE, new subspecies 



Plate 36, Figure 5 



A large series of specimens from a number of stations on the north 

 face of El Palenque, while agreeing fairly well in size with C. {G .) 

 iiimdiam figuroense, are paler in coloration and a little more strongly 

 sculptured. 



The type, U.S.N.M. no. 367756, has 4 and the basal half of the 

 first of the remaining turns and measures: Length, 17.8 mm; greater 

 diameter. 12.2 mm ; lesser diameter, 7.2 mm. 



CHONDROPOMA (CHONDROPOMARTES) IRRADIANS CAMARONENSE, new subspecies 



Plate 36, Figure 2 



This race, which comes from the Sierra de Camarones, is as small 

 and as stout as C. {€.) irradians candicans but of buff instead of 

 white ground color. The outer peristome is unusually broadly ex- 

 panded. 



The type, U.S.N.M. no. 499607, comes from a cliff about 500 meters 

 west of Peiia del Leon. It has about 4.5 whorls remaining and 

 measures: Length, 15.4 mm; greater diameter, 11.8 mm; lesser di- 

 ameter, 6.5 mm. 



CHONDROPOMA (CHONDROPOMARTES) IRRADIANS CANDICANS, new subspecies 



Plate 36. Figure 1 



This, the palest of all the known races, has the ground color white, 

 which renders the interrupted spiral bands of brown c^uite contrasted. 

 The sculpture is also a little finer than in the other subspecies. In 

 size it agrees with C. (C.) iiradians camaronense.
