This subspecies ranges from Habana to Lomas de Camoa, in 

 Habana Province. It is distinguished from the others in being larger, 

 with the ribs more closely spaced. 



The specimen figured, U.S.N.M. No. 57312, was received from 

 Arango. It has 52 axial ribs on the first of the remaining turns and 

 180 on the last; it has a little more than 4 whorls remaining and 

 measures: Length, 9.4 mm,; greater diameter, 4.8 mm.; lesser diam- 

 eter, 4.0 mm. 



Of the animal of this species Gundlach states: "Animal pale, the 

 sides with a violet sheen; antennae pale orange colored; eyes very 

 black."

This subspecies was described by Arango from Santo Cristo de la 

 Salud, Habana Province. We have also seen it from Managua and 

 Bejucal, Habana Province. It is smaller than the typical race, with 

 the axial ribs much more distantly spaced, but weakly developed as in 

 the typical form. 



The specimen figured, U.S.N.M. No. 355567, was received by Dr. 

 de la Torre from Arango. It has 60 axial ribs on the first of the re- 

 maining turns and 86 on the last; it has a little more than 3 whorls 

 remaining and measures: Length, 6.7 mm, ; greater diameter, 3.8 mm. ; 

 lesser diameter, 3.1 mm.
