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 shouidered 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.
