80 GENUSBUCCINUM. 



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. Payraudeau, 

 in his Catalogue de la Corse, p. 157, pi. 7, fig. 23-24, names, 

 likewise, BUCCINUM macula a variety which is more elongated 

 than that of Montagu. We have figured it, pi. 20, fig. 78. 

 This author gives the name BUCCINUM Lacepedii, to a variety 

 smaller, and of an uniform color, which we give, pi. 20, fig. 77. 

 The PLANAXIS affinis and rosacea of Risso, also, should be 

 restored to this species.

Shell ovate, conical, of an ash-gray color ; ornamented with 

 a reddish zone at the suture, and another, much wider and 

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

 spire composed of seven rounded, swollen whirls, provided
