CUBAN SUBFAMILY CHONDROPOMINAE TORRE AND BARTSCH 217 



men, having 5.2 whorls remaining, and measures: Length, 19.0 mm; 

 greater diameter, 16.9 mm; lesser diameter, 11.8 mm. 



The distribution of this race, so far as kno^Yn, ranges from Los 

 Portales into the Abra de Caiguanabo, where it meets C . {G .) cxqiiisl- 

 tum exqiusitum. 



CHONDROPOMETES (CHONDROTHYROMA) EXQUISITUM CEREUM, new subspecies 

 Plate 11, Figure 13 



Shell pale Avax yelloAv, darker on the early whorls, with a mod- 

 erately broad and not very dark axial band of brown immediately 

 behind the peristome, which is faintly yellowish. 



The type, a complete specimen, L^.S.N.M. no. 428801, comes from 

 the east end of the Sierra Guacamayas. It has 6.0 whorls and 

 measures: Length, 18.4 mm; greater diameter, 17.2 mm; lesser di- 

 ameter, 12.0 mm. 



CHONDROPOMETES (CHONDROTHYROMA) SAGEBIENI (Poey) 



This species embraces small shells of bright red or reddish color 

 with red operculum. It occupies the region between Mendoza or 

 Paso Real eastward through the Sierra Guane to mogote Punta 

 de la Sierra. It breaks up into five subspecies, which the following 

 key will help to differentiate. 



Distribution of the subspecies of G. {€.) sagehieni is shown in 

 figure 75,

 Isla de Cuba, vol. 2, p. 33. 



This is a little smaller than C. (C.) sagehieni mendozense and of 

 bright red color, with an even more flaming peristome. The color 

 extends a little beyond the peristome on the last whorl. No spiral 

 markings have been observed on any of the specimens.
