CUBAX SUBFAMILY CHONDROPOMINAE TOKRE AND BARTSCH 219 



The specimen figured, U.S.N.M. no. 355012, is one of a series from 

 Sierra de Guane. It has 3.5 whorls and measures : Length, 16.2 mm ; 

 greater diameter, 13.7 mm ; lesser diameter, 11.0 mm. 



CHONDROPOMETES (CHONDROTHYROMA) SAGEBIENI PORTALESENSE, new subspecies 



Plate 11, Figure 12 



Shell pale red, with the inner peristome and the region imme- 

 diately behind the peristome on the last whorl a fiery red. The 

 shell is strongly, almost continuously, spirally banded. These spiral 

 markings are accentuated at intervals and produce an axially as well 

 as a spirally banded effect. 



The type, U.S.N.M. no. 367737, was collected by Dr. de la Torre 

 at Los Portales. It has 3.5 whorls remaining and measures: 

 Length. 15.7 nun; greater diameter, 13.8 mm; lesser diameter, 9.7 mm. 



CHONDROPOMETES (CHONDROTHYROMA) SAGEBIENI MENDOZENSE, new subspecies 



Pl^TE 11, FiGUBE 3 



In this subspecies the shell is pale brown, the early whorls darker. 

 The inner half of the peristome is flame red, the outer paler. This 

 bright color also characterizes the rather broad axial band immedi- 

 ately behind the peristome. The whorls are marked by not strongly 

 pronounced interrujited spiral bands of brown. 



The type, U.S.N.M. no. 355015, and a series of this species we col- 

 lected on the Tomas Barrera Expedition in a limestone block immedi- 

 ately adjacent to tlie station at Mencloza or Paso Keal. This has 

 nothing to do with the Sierra de Paso Real but is several miles south- 

 west of this. The type has almost 4 whorls remaining and meas- 

 ures: Length, 18.3 mm; greater diameter, 15.9 mm; lesser diameter, 

 ll.S mm. 



CHONDROPOMETES (CHONDROTHYROMA) SAGEBIENI PARVUM, new subspecies 



Plate 11, Figure 5 



Shell very small, pale reddish with the early whorls rather darker 

 in color. Inner peristome pale red; spiral bands present, but very 

 inconspicuous. 



The type, U.S.N.M. no. 367747, was collected by Arango at Teneria 

 north of Portales. It has 4 whorls remaining and measures : Length, 

 13.0 mm ; greater diameter, 10.5 mm ; lesser diameter, 8.0 mm. 



A large series of specimens collected about La Murralia on both 

 sides of the road agree rather well with the specimens from Teneria.
