42 GENUS BUCCINUM. 
Length 11 lines. Width 6 lines. 
Inhabits the Mediterranean, the coasts of Provence, Corsica, 
and the Isles of Hiéres. 
This is a Bucctnum, as has been fully settled by Payraudeau 
in his catalogue of the Annelides of Corsica; Blainville impro- 
perly placed it among the CanceLLari& ; the principal character 
of this genus does not exist in the shell which we are describ- 
ing; it is rare to perceive even a fold upon the columella of this 
last, except in very young specimens. Male specimens are al- 
ways much smaller, and never exceed 5 or 6 lines in length. 
The internal folds of the lip are also very strongly prominent. 
This shell so much resembles our variety A, of the Buccinum 
undosum, that it might almost be asserted to belong to that spe- 
cies, and be considered as merely alocal variety ; nevertheless, 
it is smaller than that shell, less turgid, with less prominent 
ridges, the longitudinal ribs more approximate. Its coloring is 
the same, only the white band of the lowest whirl is better 
formed and more distinct.

Shell ovate, inflated, solid, covered with a fawn colored or. 
reddish epidermis ; spire short, slightly obtuse, pointed at its 
summit. ‘The whirls are six or seven in number, and very 
approximate ; the four or five upper ones are conical, covered 
with sub-nodulous, longitudinal folds, which gradually become 
effaced, and disappear altogether upon the lower whirl. ‘This
