Arranged by Pr. Pfeifi"er as a variety of IT. binlrialis, 



but subsequently separated by him from that species.

 The Prince Helix. Shell imperforated, oblong-tur-

 a slight hydrophanous cpidcnnis ; aperture lunar-

Bai. ? 



This shell, collected by Sir Edward Belcher in the voy- 

 age of the Samarang, is probably from one of the Philippmr 

 Islands. It is allied to //. eoccomelos, but of a more de- 

 cided oblong-turbinatcd form, with the columellar margin 

 more apprcssly callously drawn out.
