Leptopoma pellucidum, Pieitfer. 
Hab. Philippine Islands; Cuming. 
The fulvous zones which encircle this species wili be 
found, on examining them with the lens, to consist of 
closely-packed waved lines.

lari, subampla, labro albido, late plano-eapanso. 
The FLEA-SPOTTED Lepropoma. Shell very narrowly 
umbilicated, globosely turbinated, thin, rather in-

broadly flatly expanded. 
Preirrer, MS. in Mus. Cuming. 
Hab. Island of Batchian, Eastern Archipelago; Wallace.
