larger volution, and often tinged with grfc'eri towards die 
outer-lip ; the first very large and cylindrical; the others 
small and hardly raised; the outer-lip thin/ with two or 
three tubercles near the margin ; pillar with from two to 
four tooth-like folds: length half an inch; breadth not a 
quarter. 
The tubercles on theouter4ip are seldom to be observed, 
and we rather suspect that the present and the next spe* 
cics have been generally combined together.

3. Voluta ringens. Double-toothed Volute. 
Shell oval, tapering to a rather obtuse point,- whitish 
horn-color, transparent: spires six or seven, founded and 
well defined, striate or wrinkled longitudinally, the first 
volution large and occupying more than half the shell: aper¬ 
ture narrow-oval, the outer-lip very thin, with four or five 
Slight white teeth, which are placed rather within the' 
mouth, and are visible through the shell on the back; pil¬ 
lar with four white teeth, the second from the base very 
large : length a quarter of an inch ; breadth more than a 
third of its length; 
Found with the last, from which it differs in size, color, 
transparency, rounded volutions, and the distinct teeth on 
the outer-lip which are uniform and constant, and never ap¬ 
pear like tubercles. And from the next, in wanting the sub- 
opake milk-white color, in the distinct volutions, and the 
teeth, v. v.
