 Hab. Zebu, Philippinarum. Mus. Metcalfe, Cuming. 

 This elegant shell bears some resemblance to the preceding, but 

 its shape alone would be sufficient to distinguish it. The colouring 

 matter seems to be deposited only on the lamellae. The lunule is 

 rather large for this genus.

This extremely rare shell, concerning which Mr. Dillwyn remarks 

 that no subsequent author has recognized it, still exists in Linnaeus' 

 cabinet, and with the exception of a few young shells in the collec- 

 tion at the Chinese Exhibition, I have never met with any specimens 

 elsewhere.

Allied to the last, but the mouth is far smaller in proportion to 

 the length of the spire. The plait lies so far back on the columella 

 as not to be discerned by the careless observer.
