U.S.N.M. no. 313591 contains nine specimens from Calawagan, 

 northeastern Mindoro, which in part agree with the present race and 

 in part tend toward the dark-colored Cochlostyla (Calocochlea) subatra. 

 I am placing them provisionally here. They yield the following meas- 

 urements: 



This race differs from C. (C.) roissyana bartschi in being uniformly 

 lighter colored.
