In this race the shell is elongate-ovate. The aperture is rather 

 flaring and the periphery obtusely angulated. A light zone may or 

 may not be present at the periphery when the periostracum is re- 

 moved. The peristome is chocolate-brown. The shell differs from 

 Cochlostyla rufogaster monozona in being much larger and in having 

 the periphery angulated. It differs from Cochlostyla rufogaster an- 

 tipolana and Cochlostyla rufogaster montalbana in being less broadly 

 ovate. 



I believe that this race will be found in most collections labeled 

 Cochlostyla rufogaster. 



Specimens examined. — The type, U.S.N.M. No. 310305, figured, is 

 one of two collected by the Exploring Expedition at Manila. It has 

 6.3 whorls, and measures : Height, 69 mm ; greater diameter, 47.5 mm. 

 The other specimen, U.S.N.M. No. 7611, has 6.2 whorls, and measures : 

 Height: 70.5 mm; greater diameter, 50.7 mm. There are 12 addi- 

 tional specimens in the collection, which undoubtedly belong here, 

 received mostly from the old collectors and labeled Philippine 

 Islands or Luzon. I am not giving measurements of these because 

 specific locality data are missing.
