KEY TO THE SUBSPECIES OF PARACHONDRIA (PARACHONDROPS) ERECTA 



Spiral sculpture on last whorl strong. 

 Interrupted color bands strong. 



Axial riblets closely spaced mayensis 



Axial riblets distantly spaced ramonensis 



Interrupted color bands feeble erecta 



Spiral sculpture on last whorl feeble turquinensis 



PARACHONDRIA (PARACHONDROPS) ERECTA MAYENSIS, new subspecies 



Plate 20, Figure 1 



This race, which was collected by Dr. Ramsden at Isabelita planta- 

 tion, La Maya, Oriente, has the axial riblets almost as closely approxi- 

 mated as those in typical P. (P.) erecta erecta, but they are a little less 

 elevated. It agrees with P. (P.) erecta ramonensis in having the strong 

 interrupted spiral bands of brown. The peristome is separated from 

 the preceding turn at the parietal wall. 



The type, U.vS.N.M. No. 367778, has 4.2 whorls remaining, and 

 measures: Length, 14.0 mm.; greater diameter, 7.2 mm.; lesser 

 diameter, 6.1 mm. 



PARACHONDRIA (PARACHONDROPS) ERECTA RAMONENSIS. new subspecies 



Plate 20, Figure 4 



This subspecies was collected by Gundlach at El Ramon, east of 

 Santiago. It differs from the typical race in being smaller, in having 

 the whorls a little more rounded, and in having the axial ribs more 

 distantly spaced and m.ore irregular in development; that is, heavy and 

 fine riblets are present. The tufts at the summit are also heavier and 

 are less inclined to consist of fused riblets. The interrupted spiral 

 bands of brown are quite strong, and the peristome at the parietal 

 wall touches the preceding turn. 



The type, U.S.N.M. No. 367780, has 4.2 whorls remaining and 

 measures: Length, 13.7 nun.; greater diameter, 7.0 mm.; lesser 

 diameter, 6.3 mm.

 larger than the others and it has the spiral sculpture on the last whorl
