very thick. Another 1 have seen at Mrs. Mawe's, and one is in the 

 British Museum : but the finest specimen in colour and preser- 

 vation is in the possession of my friend W. J.Broederip, Esq., 

 of Lincoln's-Inn : from this it seems the spiral whorls are finely 

 and delicately marked by transverse elevated strise, while those 

 on the basal volution are striated transversely, though in a less 

 regular manner. 



Bruguiere mentions that this species is generally found in the 

 South American islands, Cayenne, and Guiana. 



Mr. Dillwyn has given the new nameof ««re« to this shell, in 

 addition to the five others under which different authors have 

 described it. Such changing of names and multiplication of syno- 

 nyms, without strong reasons, are very objectionable. I have 

 retained that of Bruguiere, as being the only author who has 

 placed it in its proper genus.
