Shell straight, elongate-conic, bluish-white when the animal has been 
removed. When the animal has been allowed to dry in the shell, it appears 
through the substance of the shell and gives it a mottled brownish aspect. 
The brownish coloration when present usually extends over the upper half 
of the specimen. Whorls flattened, decidedly appressed at the summit. 
Sutures appearing as a very fine impressed line. Base moderately long, 
well-rounded. Aperture oval; posterior angle very acute; outer lip thin at 
the edge, bent back immediately below the summit, then forward to form 
a claw-shaped element, the center of which coincides with the periphery; 
there is another backward deflection of the outer lip at its junction with 
the inner lip, which is moderately strong, curved and twisted and partly 
reflected over and adnate to the base; parietal wall covered with a mod¬ 
erately thick -callus. (Bartsch.)
