88 GENUS BUCCINUM. 
90. BUCCINUM MARGINULATUM, Lam. The Margined 
Buccinum. 
(Collect. Mass. Lam.) Guautrert, pl. 44, fig. n. 
Pl. XXIX, fig. 117. 
B. testa ovato-acutd, plicis tenuibus longitudinalibus confertis striisque 
transversis decussata, subgranulosd, colore yarid; anfractuum margine 
superiore crassiusculo, crenulato ; spird exsertiuscula ; labro intuts striato. 
Shell ovate, slightly ventricose ; spire pointed, formed of 
six or seven whirls, rounded upon their upper part, separated 
by a pretty deep and slightly canaliculated suture. The whole 
surface is. very regularly chequered by approximate, longitu- 
dinal striz, and by other transverse striz, not less regular than 
the first. Aperture white, callous, sub-rounded. Right lip 
thick, striated internally ; columella covered by a wide, rather 
thick callosity, ornamented lengthwise with small, irregular 
wrinkles. The coloring of this shell is grayish, or of a pale, 
uniform fawn-color, presenting upon the whirls one or several 
transverse brown or whitish bands. 
Length 8 lines. Width 5 lines. 
Inhabits the Mediterranean, the coasts of Naples, of Bar- 
bary, and the Seas of Sunda. 
Young specimens of this shell were brought from the last 
locality by Bellanger, who has given a figure of it, in his 
account of his voyage to the East Indies, pl. 3, fig. 6 et 7. 
Deshayes has given it the name of Buccinum conoidale. See 
also our pl. 27, fig. 109. This shell differs from the adult only 
in the right lip which is thinner, and in the callosity, which is 
less prominent.
