 number. The lower transverse band is elevated into a distinct keel around the 

 base.

This is a rare species, at least in my cabinet. The volutions are covered with 

 prominent transverse or spiral ridges, between which there are finer strias. A pro- 

 minent obtuse keel runs round the base of the volution, and the peristome is re- 

 flected all round the aperture, particularly at the base of the columella. This shell 

 is probably only a variety of Turbo lamellosus, Broc. (p. 379, t. 7, f. 2), although it 

 does not appear to be so much fringed as the Italian fossil. I would nevertheless 

 have given it Brocchi's name, but that it has been used by- Lamarck for another 

 species.

Shell tapering and turriculate, with an imperforate base ; volutions rounded, 

 covered with numerous large, smooth, close-set lamelliform, and acutely-pointed or 

 hooked-shaped costas, with an occasionally thickened subvariformed rib ; striated 

 or ridged spirally, with an obsolete keel upon the base.

I have but one specimen of this shell, which, however, appears to differ so 

 materially from any species I am acquainted with, that I feel disposed to consider 

 it as distinct, and have given it a name for the present until the possession of a 

 few more individuals will either confirm its correctness or remove it to one of its 

 congeners. The same might almost be said of one or two others of this genus,
