body whorl of the shell. One pair of these teeth is placed in the 
throat, so near to the lahrum as readily to be seen by looking in 
at the aperture. These teeth are nearly equidistant from each 
other, and from the extremities of the lahrum. The other pair is 
placed so far within the shell as not to be seen at all from the 
aperture. 
I found several specimens in a humid situation at Harrigate. 
Bolimus mutilatus. — Shell turriculated, pale reddish brown ; 
whorls four, longitudinally striated with irregular elevated lines 
or wrinkles, which are a little more prominent near the sutures ; 
suture not deeply indented } apex widely truncated ; lahrum 
whitish, destitute of calcareous deposit ; body whorl more than 
double the width of the truncated apex; spire one and a half 
times longer than the aperture. Length less than one inch ; width 
less than half an inch ; length of the aperture two-fifths of an 
inch. 
Inhabits South Carolina, about Charleston. 
This curious shell is the first and only species of the genus 
Bulimus, native of the United States, that I have yet seen. I am 
indebted for it to the researches of Mr. Stephen Elliott, of 
Charleston, who informs me that it is there found in gardens. In 
the truncated form of the apex of the spire, this species resembles 
the decoUata, consolidata, truncata, and Pupa torticollis, &c., but 
it is suflttciently distinct from the former, to which it is more 
closely allied than to the others, by its less cylindrical and more 
conic form, being much more robust in its figure and less elongated ; 
the aperture is consequently wider, and forms a greater proportion 
of the total length. It does not change to an opake white after 
the death of the animal, as the decoUata generally does. 
Pupa contracta. — Shell dextral, short, subovate, white ; apex 
obtuse; whorls five; umbilicus distinct; aperture regularly 
orbicular, complete, the lamina of the labium being elevated 
above the surface of the preceding whorl, and joining the extremi- 
ties of the labia ; labium with a large, elongated, prominent tooth, 
which is concave on the side towards the lahrum ; lahrum 
bidentate, a large tooth or fold far within the throat, caused by 
the fold of the umbilicus ; throat much contracted by the large 
tooth of the lahrum into the form of a horse-shoe. 
Total length less than one-tenth of an inch. Inhabits Virginia.
