COLUMBELLA. 



seen this, and therefore we mention it in our Latin generic 

 character, as a character not given on our own personal 

 responsibility, though we are disposed to believe it to be 

 the case, and that this genus is therefore related toRicinula. 

 Bruguiere has placed some of the species among the Mitrae, 

 in plates 374 and 375 of the Encycl. Methodique, and 

 under the article Buccinum in the text, he describes several 

 others. 



The following are the specific characters of such spe- 

 cies of this Genus represented in our plate, as we do not 

 find hitherto named : we have figured the extremes to which 

 it seems to go in respect of its most important characters ; 

 those to which we do not add a Latin phrase are named in 

 former works. A singular variety of C. mercatoria, is 

 added to our plate, fig. 9. The Columbellae are marine ; 

 no fossil species are known.

A pretty little shell, confounded by Adausnnj and, we believe, by 

 all former writers with Buccinum oitiduluui, of which they have 

 regarded it as a variety. The one we have represented under the 

 name of Columbella nitidula^ is the more like of the two to A dan- 

 son's Bigni^ and which differs from this in having the aperture 

 proportionably longer and the internal tumour of tlie outer Uj* 

 more distinct.
