This species is remarkable for having a double lip, the inner or 
newer portion of which is not quite so much expanded as the outer. 
It may be regarded as the first link of affinity, connecting Cyclosto- 
ma with Pupina by the intervention of the next species, C. Pupini- 
forme.

This species, which is related to the last and to Cycl. tortuosum of 
Gray, approaches very nearly to the genus Pupina, appearing to 
differ only in having a dull unpolished external surface, while that 
of Pupina is extremely brilliant. It proves the genera Cyclostoma 
and Pupina to belong to the same family. 
The next communication is from Dr. L. Pfeiffer, and contains the 
following descriptions of shells belonging to the genera Helix and 
Bulimus, also collected by H. Cuming, Esq. in the Philippine Islands.
