PHASIANELLAo Lamarck , Phasianus^ 
MontforL 
Gen. Char. An oblong subturreted pointed uni- 
valve ; aperture entire,, longer than wide ; left 
lip sharp ; right lip reflect d over the last 
whorl ; a longitudinal ridge upon the columella, 
A Genus instituted by Lamarck ; it is distinguished 
from his Lymuaea by the thick edge of the right lip not 
entering the mouth, but reposing upon the body of the 
shell. In general, also, the whorls are more equal than 
in that Genus, and the shell is thicker, opaque, and va- 
riegated. 
The recent species inhabit the shores of islands in the 
neighbourhood of New Holland. 
PHASIANELLA orbicularis. 
TAB. CLXXV. — Fig. 1. 
Spec. Char. Conical, acute, smooth ; whorls 
about six, ventricose ; aperture nearly round. 
This is nearly related to the Genus Vivipara, but the 
spire is too much elevated and too acute ; it is marked 
with lines of growth, and the smaller whorls have a few 
obscure transverse lines upon them. There is apparently 
an open umbilicus ; but if the shell were full grown or 
perfect, it would probably be covered, as it is, but narrow. 
I have referred to this species of Phasianella in the de- 
scription of Helix globosus, tab. 170, along with which
