This is rather an unsatisfactory species, though certainly not re- 

 ferable to any hitherto described.

 low water) ; Cuming. 



However closely this shell may approximate to the Mitra ejraspe- 

 rata, it is uniformly white, and always exhibits a stroug peculiarity 

 in the band which appears in the interstices and not upon the summit 

 of the ribs.

This beautiful species, which I have the pleasure of dedicating to 

 a most zealous labourer in the field of conchological research, may 

 be recognised by its graceful form and by the keel-like elevation of 

 the ribs.
