80 GENUS BUCCINUM. 
Inhabits the Channel, on the coasts of France and England, 
the Atlantic, and the Mediterranean, where it is very common. 
This shell is so variable in its form, which is more or less 
elongated, and particularly in its coloring, that some authors 
have subdivided it into several species. These infinite divisions 
in science are a perfect chaos, engrossing all our time and 
memory in the study of endless nomenclatures. . It would be 
useful to compare together, as much as possible, species of the 
same latitudes; and if, in a series of specimens, we recog- , 
nised only differences of size and color, to establish them ac- 
cordingly, as local varieties; these differences usually depend- 
ing, in fact, upon mere modifications, occasioned by the different 
places which they inhabit. 
Montagu gives the shell we have described, Test. Brit., p. 247, 
t. A, fig. 4, under the name of Buccinum macula. Parrende a, 
in his Catalogue de la Corse, p. 157, pl. 7, fig. 23-24, names, 
likewise, Bucctnum macula a variety which is more elongated 
than that of Montagu. We have figured it, pl. 20, fig. 78. 
This author gives the name Buccinum Lacepedii, to a variety 
smaller, and of an uniform color, which we give, pl. 20, fig. 77. 
The Puianaxis affinis and rosacea of Risso, also, should be 
restored to this species.

more deeply colored band, at the base of the lowest whirl ;
