54 GENUS BUCCINUM. 
54, BUCCINUM SUTURALE, Lam. The Sutured Buccinum. 
(Collect. Mass. Lam.) Cuemn. pl. 125, fig. 1199-1200. 
Pl. XXIV, fig. 96. 
B. testa ovato-conica, levi, nitida, alba, luteo-nebulosA ; anfractibus con- 
vexiusculis, prope suturas noduliferis, supremis longitudinaliter plicatis ; 
apertura levi; labro postice denticulato. 
Shell ovate, conical, smooth, shining, whitish, sometimes of 
a flesh color, marked with spots, and oftentimes with reddish 
lines or flammules ; spire composed of seven slightly convex 
whirls, with noduliferous tubercles near the sutures ; the first 
four or five are marked with small longitudinal folds; the 
others have pretty fine, distant, transverse brown lines, as 
many as eight or nine upon the lowest whirl : upon the base 
of this are observed delicate furrows. Aperture ovate, round- 
ed, white, smooth, terminated above by a small, dilated canal, 
which is formed by a re-entermg angle from the right lip, and 
a transverse tooth from the left lip. 'The,right lip is effuse, 
arcuated, thin, armed at the base with five or six small den- 
ticulations. The left lip consists of a plate which laps over a 
little upon the body of the shell, and forms a small keel. 
Columella smooth. 
Length 13 lines. Width 6 lines. 
Inhabits the coasts of the Isle of France. 
This shell so strongly resembles the B. glans, that it ought, 
unquestionably, to be united to that species. It has all its 
characteristics, and the only differences which can be perceived, 
are doubtless attributable to age or locality. The shell we have 
just described is much smaller, the color less deep, the transverse 
lines less marked ; the tubercles near the sutures are also very 
prominent upon the last whirls, whilst they are but indistinctly 
seen, or disappear altogether in the Buccinum glans.
