60 GENUS BUCCINUM. 
60. BUCCINUM CANALICULATUM, Lam. The Channeled 
Buccinum, 
(Collect. Mass. Lam.) Marr., Cuemn., pl. 125, 
fic. 1194-1195. | 
Pl. X X11, fig. 89. 
B. testA ovato-conicd, superne longitudinaliter plicata, basi striata, pal- 
lidé fulva, interdim castaneo-bizonata ; anfractibus superné canaliculatis, 
duobus infimis dorso levibus; apertura ovata, alba, fundo fused; labro 
dextro crasso, intus striato. 
Shell ovate, conical, somewhat ventricose, of a pale fawn 
color, spire composed of eight whirls; upper ones longitudi- 
nally folded, and slightly striated transversely ; the two lower 
ones smooth, convex and strongly canaliculated ; the lowest 
furrowed at the base, and frequently ornamented about the 
middle with two bands of a chestnut-color. Aperture ovate, 
white, cavity brown; right lip thick, denticulated upon the 
edge of the lower part, striated within ; left lip gives rise to a 
thin and elevated callosity upon the edge of the columella, 
and towards the top a very prominent transverse fold, forming | 
the commencement of a canal. 
Length 17 lines. Width 8 lines. 
Inhabits the Indian Ocean. 
This shell, which has been established as a species by La- 
marck, should, I think, be again united to the B. olivaceum, and 
should be regarded as a constant variety, either of sex or locality. 
In some specimens the whirls of the spire are less canaliculated, 
and the longitudinal folds slightly appear, as in the species to 
which I presume they belong.
