MOLLUSCA 385 
Two species collected by Mr Perkins still await identification; they are not 
improbably new, but so many of the described species are unknown to me that I 
consider it safer to leave them for the present. One is from Honolulu and Waianae 
Mts. in Oahu, with a dwarf variety from the mountains of Molokai at 4000 feet ; the 
other from Kau, Hawaii: both belong to the group of S. caze/la Gould.
