The thin shell is ventricose, thin. The
spire is short. The
body whorl and the
aperture are very large. The
operculum is usually wanting, but, when present, at first with apical nucleus, afterwards becoming annular. (Described as
Pseudobuccinum) The thin shell is oval and ventricose. The spire is very short. The body whorls is large, not produced below. The aperture is large, terminating below in a rounded sinus. The outer lip is thin and simple. The inner lip is very thin, smooth, and closely and very broadly folded upon the imperforate umbilical region and body whorl above, so as to form, with a low revolving umbilical ridge, a kind of profoundly arcuate, strongly spiral, false columella. The surface shows more or less distinct revolving lines and furrows. This genus differs in its simple foot and in possessing eyes as well as in dentition. The form and porcellaneous texture of the shell are like
Bullia, and serve to separate it from
Buccinum. The animal is like
Buccinum, of a white color sparsely sprinkled with black on the head, foot and siphon; the tentacles are broad, close together at the base, and rather short, with the eyes on the outer side, near the middle; the siphon is thick and short, and the foot is fleshy and simple behind. ==Distribution==
