which are covered with small grayish points; but the most re- 
markable variety is that which we give, pl. XIII, fig. 44, upon 
which is beautifully delineated a foliaceous band which covers 
the whirls and the body of the shell.

Pl. XVI, fig. 56; et pl. XIV, fig. 47, young. 
B. testa parvula, oblongo-conica, angusta, levi, nitidd, cornea, maculis 
fulvis aut rubris ornat4é; anfractibus connatis; labro intis dentato. 
Shell small, pretty thick, oblong, cylindrical, subturreted, 
smooth, white or of a variegated color, marked with brown or 
bright fawn colored spots or waved and zigzag longitudinal 
lines ; spire very pointed, composed of six or seven scarcely 
convex whirls ; sutures indistinct. Aperture narrow, elongat- 
ed, of an orange color; right lip pretty thin, denticulated 
within. Columella generally smooth, without guttules, at its 
base. 
Length 6 to 7 lines. Width 22 lines. 
_ Inhabits the Mediterranean, the coasts of Provence, Corsica 
and Sicily. 
This shell has altogether the aspect of the Buccinum Gervillii ; 
and it is only after an attentive examination, that we finally dis- 
cover the characters which serve to distinguish it from that. In 
the B. corniculatum, the denticulations of the right lip are less 
numerous, and the aperture is of an orange color, whilst, on the 
contrary, it is of a violaceous white in the B. Gervillit. Blain- 
ville had also placed this shell among the CoLumBetia, which 
it somewhat resembles in the aperture, which is narrow in both 
species, and in the right lip, being very gently swollen towards 
its middle. 
We shall give, at the end of this monograph, the situation 
which should be assigned to the shells which we shall have
