of new and rare Volutoe, S3 



rest of the shell, — the uppermost of these bands wreaths the coro- 

 net of tubercles ; spire moderate, the apex sub-papillary and 

 somewhat granulated; pillar 4-plaited. Length 2 inches 4 

 tenths. 



This elegant shell, one of the gems of the Tankerville collec- 

 tion, in the catalogue of which it is first named and described by 

 Mr. G. B* Sowerby, is the most slender which I have yet seen 

 with the granulated apex. The tuberculated whorls gradually 

 lose themselves in granulations, and these last terminate in the 

 subgranulations of the apex, which, though still papillary, is much 

 more acuminated than in any other species composing the group. 



Its colouring, particularly in its snow-spots, reminds us of V. 

 nivosa; while its form, as Mr. Sowerby observes, approaches that 

 of some of the elongated varieties of V. vespertilio. It appears 

 to me with its sub-granulated apex, tuberculated whorls, sub- 

 fusiform shape, and somewhat produced spire, to lead us towards 

 those fusiform Volutes which have the spire very much produced, 

 such, for instance, as V. Paci/ica (Chemn.), and V. gracilis (Swain- 

 son), while the granulations are strongly marked on their attenu- 

 ated spire, even up to the papilla or apex, which, however, is 

 quite smooth. 



If my recollection is right I have seen a second specimen of 

 this shell in the collection of Mr. Spurrett. I never saw or heard 

 of any others. Of its locality I am ignorant : my strong suspi- 

 cions point to the South Seas.
