Shell nearly cylindrical, very obtuse, dark horn-color, 
glossy, transparent: spires six, rounded and well defined 
by the separating line, finely striate or wrinkled longitudi¬ 
nally : aperture somewhat orbicular, a little produced at 
the base, with abroad flat glossy-white margin, and a tooth 
close to the front of the mouth and placed near the outer- 
lip, appearing as if it were a curved continuation of the outer 
rim ; pillar-lip with a large and deep perforation behind it:

Shell cylindrical, very obtuse, nearly opake, yellowish 
white or pale horn-color: spires seven, rounded, wrinkled 
and shaped like the last: aperture orbicular, inclining to a 
crescent-shape, and not produced at the base; the outer 
edge very thin, and not in the least margined, on the back 
of which is a strong raised rounded rib extending from the 
outer angle to the perforation behind the pillar; the tooth 
is either very obscure or very minute, placed far within the 
mouth, exactly in the centre between the two lips, and not 
near one side as in the last: length two-tenths of an inch ; 
breadth not a third of its length.

it may be known at a single glance, by its larger size, more 
cylindrical form, and yellowish-white or cream-colored hue.
