DESCRIPTION. 
169 
Inhabits Tranquebar and Ceylon. 
It is without any hesitation that this species is 
transferred from Voluta to Murex. The outline of 
the aperture is so absolutely characteristic of the 
latter, that it neutralises the claim of the toothed 
columella, which is not confined to the former. 
The teeth are nearly horizontal, and not oblique, 
as is usual in Voluta. No species can better illus- 
trate the plaited section which has been proposed 
in the description of the genus Murex, than this, 
which possesses no property in common with its 
present congeners but its teeth. The specific name 
is changed from "Pyrum to dentatus, because there 
is already a Murex Pyrum.
