On leaving the body it sweeps at once backwards, leaving a very narrow shelf between the body whorl and the sinus. The sinus is rounded, rather shallow and open, but large, from the very considerable forward sweep of the pinion-like edge of the lip as it approaches the siphonal canal, from which it retreats toward the point of the shell. The inner lip is a thinly glazed, narrow, slightly depressed area. It is very slightly hollowed at the base of the longish finely conical columella. The point of the columella is cut off with a long-drawn obliquity, and has a fine, slightly twisted edge. This species occurs in the demersal zone of the Atlantic Ocean from Florida to Brazil at depths between 85 mm and 640 m.
