MlTRA, J. 



'] ml in 1 " oblong, with a l<'\v large plica- on tlic columella, the 

 ;he large j'ire usually pointed and 



elongated. St-vcia! species ;IP> hrilli;iiitly ^potted witli red on a 

 whin- ground*. The foot of the animal is small: th<> tcntacula arc 

 of a moderate length, with the eyes on the side, near their inferior 

 third ; tin* siphon also is of a moderate length, but it frequently pro- 

 trudes a proboscis longer than its shell. 



CANCELLARIA, Lam. 



Tln last whorl ventricose; aperture ample and round, the internal 

 margin forming a plate on the columella. The spire is salient and 

 1 <>ini. -d, and the surface of the shell marked with decussating sulcif- 

 The 



BUCCINUM, Lin. I 



Comprises all the shells furni^u <l with an emargination or a short 

 canal inflected to the left, and in which the columella is destitute of 



Brugiftfes Eta divided them into the four genera of Buccimim, 

 . < Wi\, and Tercbra, part of which have been again subdi- 

 '1 by Messrs de Lamarck and Montfort. The 



BUCCINUM, Brug. 



Includes the emarginated shells without any canal, whose general 

 form, as well as that of the aperture, is oval. The animals all such 

 as are known, are deprived of the veil on the head, but are furnished 

 with ;i proboscis, two separated tentacula, on the external side of 

 which are the eyes, and a horny operculum. Their siphon extends 

 out of the .shell. 



The name of Buccinum is especially applied by M. de Lamarck to 

 tin >e in which the columella is convex and naked, and the margin 

 without plicae or varix. Their foot is moderate, their proboscis long 

 and thick, and their penis, frequently, excessively large.. In the
