slightly convex, with an indistinct minute furrew below

Observations. Of this little species I have received but 
a single individual. It is more elongate than that last 
described, and, though much like it, is specifically distinct. 
The three last described differ so much in general cha- 
racter from the type of the genus, that I have not without 
much hesitation placed them here. The genus Pyrula 
seems to have equal claims for them, and the example of 
Lamarck, followed by Sowerby, alone made me conclude 
todo so. The Fusus ficulneus of these authors is one of 
this group. Like it the minor has a fold on the columella, 
which has not deterred Lamarck from placing the ficulneus 
among the Fusi, although he says in his generic descrip- 
tion, “ columella levis.”

* It is with peculiar gratification I place the name of my friend Judge 
Tait, to whose kindness I am so greatly indebted, to this fine species.
