and fimbriated costae, which in the last volution are as many as 30 in number. The 

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

Shell thick, strong, tapering, and imperforate ; apex acute ; whorls round, con-

 lamellae, curved or fringed ; base carinate ; aperture circular ; peristome reflected.

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 striee. A pro- 

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

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

 only a variety of Turbo lameUosus, 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 hook-shaped 

 costae, 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, that must for the present 

 remain separated, as they cannot be connected by anything I possess. This shell 

 presents the same differences to S.fimbriata and S. fmbriosa that S. frondicula does to
