GENUS BUCCINUM. 35 
for numerous observations upon natural history, collected in a 
voyage to the Kast Indies. Deshayes, who had charge of the 
portion relating to the Mollusca, in the narrative of that voyage, 
has figured the shell which we have described, under-the name 
of politum, on account of its analogy with the fossil shell of the 
same name, found by Basterot in the environs of Piedmont. But 
as this same name, politum, had been already given by Lamarck 
to a shell of this genus, we have thought proper to substitute for 
it the name of him who first made known this new species.

Pl. X. fig. 35. 
B. testa ovato-elongata, fusiformi, oleagined; spiraé acuté; anfractibus 
convexiusculis, superne longitudinaliter plicatis, inferné transversim 
striatis, longitudinalibus maculis spadiceis et fusco-albidis; apertura ovata, 
elongata, intus cerulescente ; columella albida, tenui; labro dextro tenui, 
intus striato. 
Shell ovate, elongated, spindle-shaped, of an olive color ; 
spire pointed, formed of six or seven slightly convex whirls, 
the lowest larger than all the others together, slightly angular, 
and flattish above. The edge of the angle in young speci- 
mens, is more prominent, and bordered by a row of pretty 
apparent tubercles, which disappear with age. Sutures slightly 
perceptible. The first three upper whirls are covered with 
very approximate small longitudinal folds; the others are or- 
namented externally merely, with numerous, regular transverse 
strie, between which are distinguished other very delicate 
ones. ‘These striz are interrupted by elongated white or red- 
dish spots, often presenting grayish flammules upon the upper 
whirls. Aperture ovate, elongated, attenuated at its two ex- 
tremities. Interior bluish. Columella whitish, smooth, almost 
straight, and a little twisted at its base. Lip straight, thin, 
sharp, lightly striated at its inner edge with brown lines. 
Length 14 lines. Width 7 lines.
