brown ; spire rather acuminated, consisting of five somewhat 

 rounded volutions, longitudinally grooved on the upper part, 

 the last volution smooth beneath ; aperture nearly round, 

 peritreme obtuse, reflected, its upper edge produced, and the 

 side towards the umbilicus rather sinuous : umbilicus small. 



First brought by Mr. Smith from Lu9on. Mr. Cuming has 

 collected many varieties, generally under decayed leaves, 

 though sometimes on leaves of trees and bushes, on several 

 of the Philippine Islands.
