This jS^ei'itii bears some resemblance to JX'. sfella, C\u, and 

 chameleon, Linn., but it differs from both in form, and may 

 ■be di&tingraslied by its broad somewhat flattened ridge.-', 

 mostly with narrow ridges intervening.

Of tins very remarkable species I liave only as yet seen 

 one specimen. It seems almost sufficient to say that it is 

 peculiarly flat, with a sharp, very prominent keel at the 

 periphery. A full description cannot yet be given, as the 

 operculum is unknown, and it may possibly rank as the type 

 of a new subgenus.
