42 GENUS B/UCCI NUM. 



Length 11 lines. Width 6 lines. 



Inhabits the Mediterranean, the coasts of Provence, Corsica, 

 and the Isles of Hieres. 



This is a BUCCINUM, 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 a local 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 

 is partly smooth, pretty strongly furrowed at its base, larger
