'75; figs. 18-19.Description.-"The dimensions of the type specin~en are: height, 10mm.; lnaxin~um diameter, 15 mm. The shell has a lo\\. spire, with about,two full volntions shown in the internal cast, with the suture well definedand with a broad, open umbilical (cavity. The first volution increasesrather rapidly in size hut the enlargement of the outer voliit~io~~is very gradual, its outer portion appearing, from tht: east, to be frec:for a short distance. In the inner portion of the sl~ell the exposed surfaceof the volutions is rounded, but in the outer roli~t,ion, especi~~llytowards the aperture, a strong revolving angle is levelo oped a littleabove the mid-height of the volution."

At tlrcjunction of the two series of raised lines are small tubercles throughoutthe entire shell. Owing to the imperfect apertures of the five specimens,its generic position remains doubtful, but its distinct sculpture willdistinguish the species.
