Shell of medium size, elongate-conic, slender, straight, surface pol¬ 
ished, glossy without perceptible sculpture, excepting irregularly dis¬ 
tributed varices. Whorls appressed at the summit to such an extent that 
the suture is scarcely perceptible; the basal portion of the preceding 
whorls shining through the substance of the succeeding turns as a false 
suture; the true suture appearing about one-third of the way between the 
summit and the false suture above the latter. Periphery of the last whorl 
rounded, base sloping in such a way as to lend the left outline a somewhat 
flattened appearance. Aperture large oval; posterior angle acute; outer 
lip decidedly protracted between the base and the posterior angle, forming 
a claw-like extension; inner lip short, moderately stout, somewhat curved, 
reflected over and appressed to the base; parietal wall covered with a 
moderately thick callus. (Bartsch.)
