GASTEROPODA. Q7 
Inhabits the Sandwich Islands, whence it was obtained and de- 
seribed by Dr. J. W. Mighels. It was also found by Mr. Couthouy 
on Mauna Kea, at an elevation of 7000 feet; and as no figure of it has 
ever been given, it was deemed: proper to introduce it here. 
The shell has also much the aspect of a Limnea, and would be 
with difficulty distinguished from S. avara. It is also allied to S. 
canella, but it is less broadly ovate, more slender, greener, and the 
columellar region is quite different.

SHELL small, short ovate, ventricose, composed of three whorls, of 
which the last is globular-ovate and moderately large, and the others 
form a well-developed spire, and are nearly disjoined from each other 
by a very profound suture. The surface is longitudinally marked with 
fine crowded lines, and has a dead, rusty-yellow colour, without lustre. 
The aperture is small, rounded-ovate, and somewhat contracted, the 
extremities of the lip having a tendency to become continuous; the 
columellar portion of the body of the shell is very small, and covered 
with callus, the outer lip returning downwards upon it; it is sharp, 
and without perceptible fold. Within, it is smooth and shining. 
Length of axis one-third of an inch; breadth two-ninths of an inch. 
Inhabits the island of Maui, Sandwich Islands. 
Much like S. avara, Say, and S. caduca, Mighels; it is, however,
