San Diego. The type, U.S.N.M. no. 493294, has 3.5 whorls remaining 

 and measures: Length, 25.6 mm; greater diameter, 17.4 mm; lesser 

 diameter, 13.7 mm.

The typical subspecies ranges from San Diego de los Banos west 

 through the mogotes leading to the Sierra la Guira, this sierra, and 

 the Abra de Caiguanabo. It is a large shell, of stumpy appearance, 

 with inflated swollen whorls having the axial riblets reduced on the 

 last whorl; the shell is thereby given a somewhat smooth appearance. 

 The shell is almost always decollated, leaving about 3.5 whorls re- 

 maining. It is very variable in coloration, presenting all the varia- 

 tions mentioned under the species. 



The specimen figured, U.S.N.M. no. 492867, was collected by John 

 B. Henderson at the mogote next to the Sierra la Guira. It is a 

 perfect specimen, having 7.0 whorls and measuring: Length, 26.1 

 mm; greater diameter, 15.9 mm; lesser diameter, 12.6 mm. 



CHONDROTHYRETES SHUTTLEWORTHI PORTICA, new subspecies 



Plate 19, Figure 7 



This subspecies ranges from the mogotes Abra de Caiguanabo to 

 Los Portales. 



This race is smaller than the typical one. It is more strongly 

 sculptured and less inflated, and the decollated shell usually has 

 4.5 whorls. It always averages darker in coloration and is usually 

 more heavily banded. 



The type, U.S.N.M. no. 468881, is a complete specimen and is 

 rather large for the subspecies. We have selected it on account of its 

 completeness. It comes from Los Portales. It has 7.2 whorls re- 

 maining and measures : Length, 28.8 mm ; greater diameter, 16.8 mm ; 

 lesser diameter, 12.2 mm. 



CHONDROTHYRETES SHUTTLEWORTHI ATRIOLA, new subspecies 



Plate 19, Figure 8 



This is a small race that comes from Los Portales, about Espejo 

 Cueva Oscura, and the Mogote Galalon. It frequently is bright red 

 in color, and the back of the expanded peristome is conspicuously 

 broadly rayed.
