 This elegant shell bears some resemblance to the preceding, but 

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

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

 rather large for this genus.

This extremely rare shell, concerning which Mr. Dilhvyn remarks 

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

 cabiuet, and \vith the exception of a few young shells in the coUec- 

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

 elsewhere.

Allied to the lašt, 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 discemed by the carekss observer. 



Odostomia turrita. Od. testd turritd, nived, Itevi, nitidd; an-

The delineations of these lašt three species will appear in the 

 ' British Marine Conchology.' The shells are from the cabinet of 

 W. Metcalfe, Esq., and \vere procured by him on one of the islets 

 near the coast of Guernsev.
