 Cab. Griiner. 



Shell ovate, dull pale blue, indistinctly banded by a darker colour ; 

 the face covered by a white callosity spreading over the columella, 

 ascending along the spire, and running into the labrum, which is 

 thus thickened even beyond what is usual ; the back shouldered and 

 slightly angular. 



It is to the liberality of M. Griiner that I am indebted for the op- 

 portunity of including this shell in these descriptions.

 Hab. Cape Blanco, west coast of Africa; in from twelve to fifteen 

 fathoms, among sand. 

 Cab. Belcher. 



With the general aspect and character of M. Cleryii, but somewhat 

 larger, more broadly shouldered, the longitudinal lines studded at 

 inters'als with dark spots, and which are somewhat regularly disposed 

 in the transverse direction ; and lastly, the spire is less elongated and 

 furnished with rather indistinct pliciform ribs.

 Hab. Cape Blanco, west coast of Africa; in thirty-five fathoms,

Readily distinguished from any species hitherto recorded by the 

 transverse, somewhat distant, and regularly disposed dark lines.
