Diagnosis

Reference	Diagnosis
J. B. Knight 1931	Of moderate size; slender, high-spired and with anterior portion of the body whorl rather slender and drawn out; sides of spire straight or very gently convex; whorl profile very gently arched; sutures very slightly impressed; inductura thin; siphonal fold low, rounded, inconspicuous, making a very low angle with the columella, bordered anteriorly by narrow and deep siphonal channel and posteriorly by a groove of similar dimensions lying between the siphonal fold and the posterior fold, posterior fold high, thin, conspicuous, ending gradually just within the aperture and scarcely visible unless some of the outer lip is broken away; surface smooth, almost polished; growth lines indistinct; color in life a uniform dark gray, almost black.
R. L. Batten 1995	Slender, fusiform shells with moderately rapid axial translation rate so that sutures form acute angle to axis. Whorl profile convex to slightly inflated. Sutures shallow but sharply defined. Base is rounded. Anomphalus. Aperture of adult is subovate. Siphonal fold very weak, low on columella, not developed on outer columellar lip. No siphonal notch on aperture.
