This race was collected by Natenson on the mogote between the 

 southeast end of the Sierra Guacamayas and Mogote Largo, to the 

 soutli of this. 



The type, U.S.N.M. no. 468922, is an almost complete specimen, 

 having lost probably the first half turn. The 5.1 whorls remaining 

 measure : Length, 22.0 mm ; greater diameter, 20.2 mm ; lesser diam- 

 eter, 15.5 mm. 



CHONDROPOMETES (CHONDROPOMETES) TORREI PALLIDULUM, new subspecies 



Plate 9, Figuke 1 



Shell similar to C. {C.) torrei favidum but with less yellow in the 

 general coloration and with the peristome flesh-color. The dark 

 axial zone behind the peristome is poorly expressed. 



This race was collected by Natenson on Mogote Largo, which is 

 the second mogote southwest of Pico Chico in the Sierra Guaca- 

 mayas. 



The type, U.S.N.M. no. 468924, is a complete specimen, having 6.0 

 whorls and measuring: Length, 23.1 mm; greater diameter, 20.8 mm; 

 lesser diameter, 15.5 mm. 



CHONDROPOMETES (CHONDROPOMETES) TORREI ALVEARE, new subspecies 



Plate 10, Figure 2 



This subspecies closely resembles C. (C.) torrei luteildbre but is 

 paler than that race and has the spiral banding practically ahvays 

 confined to the peripheral region, where it usually constitutes an 

 inconspicuous interrupted spiral band. Occasionally there is a mere 

 indication of additional bands, but the shell never bears as many 

 bands as in C. {C.) torrei luteUabre. 



The type, U.S.N.M. no. 468756, comes from Mogote Colmena de 

 Piedra, which is the southwestern part of the Sierra Galalon. This 

 is a complete specimen having 6.0 whorls and measuring: Length, 

 23.2 mm ; greater diameter, 21.8 mm ; lesser diameter, 15.8 mm. 



CHONDROPOMETES (CHONDROPOMETES) TORREI LUTEILABRE, new subspecies 



Pl.\te 10, Figure 6 



Shell small, very pale yellow with a broad axial area of dark 

 iodine purple a little distance behind the peristome. The shell also 

 has pale bands of brown, which extend upon the peristome, which is 

 pale yellow. 



This subspecies comes from the Puerto del San Andres, that is, 

 the extreme eastern end of the Sierra.
