Conus. The dentition of the following eleven species has been 
described and figured by Troschel : — C. marmoreus, nicobaricus, 
muSy pulicariuSj hebroius, mediterraneus , planorbis, lignarius, geo- 
graphus, canonicus, texiilis. The genera proposed by H. & A. 
Adams do not prove to be natural according to these investiga- 
tions ; especially the distinction of the species with coronated 
whorls from those with smooth ones docs not coincide with their 
dentition. The distinction of those Avith inflated ventricose whorls 
from those of perfectly conical shape proves to be of higher syste- 
matic value. [It is Avell knoAvn that some coronated species are dis- 
tinguishable by this character only from smooth ones, so that it 
seems scarcely to bo of specific value in all cases. The Recorder 
is inclined to consider the lineaments of colours to be more reli- 
able for systematic distinction.]
