Shell biconical, rather strong, white. Whorls 9, of which 4 form a yellowish-brown nucleus, 



with moderately convex whorls, of which about 2 upper ones smooth, 2 with curved, raised 



stri.u-, stronger just below the suture, crossed in their lower part by very fine, obliqui 



Subsequent whorls angular, the upper part slightly excavated, basal part marl)- straight in 



outline; this lower part lias rather inconspicuous axial ribs, nearl) disappearing in last whorl, 



I at the angle below the excavation ; otherwise the axial sculpture consists of rather 



stron ly rib-like, much curved, raised striao in the excavation and very fine growth-lines 5 



of spirals there are 4 '>n penultimate whorl. below and besides that accompanying the peri- 



pheral angle, and numerous spirals on last whorl. with eventually intermediate ones; tnoreover 



the shell is covered with excessivelj smal! granules, only visihle under a strong lens. Last whorl 



at first convex below angle, then moderately contracted. Aperture oblong, with a sharp angle 



ompressed, gutter-like canal below; peristome broken, sinus, judging after growth- 



but shallow, occupying the excavated space; columellar margin with a rather strong 



layer of enamel, strongest at the short canal. where it forms an oblong umbilical pit.

nical, thin, white. Whorls about 10, of which about 4 form a red-brown nucleus, 



with convex whorls, of which about i x / 9 upper ones smooth, the other ones with angular riblets, 



strongest near upper suture, crossed in their lower part by fine, oblique striae. Subsequent whorls 



with a broad, concave upper part and a much narrower lower part. The sculpture consists of 



mspicuous spirals. just below the suture, less distinctly dcveloped on last whorl. 5 much 



fainter ones in the excavation; this latter is bordered by a rather strong keel, which makes 



the whorls angular; moreover a second keel at some distance, with 2 faint intermediate ones 



on penultimate whorl: the part below the excavation on last whorl is Iirate over its whole surface. 



upper, excavated part of whorls is crossed by rather distant curved riblets. which, in crossing 



infrasutural lirae, produce small beads. At last the whole shell is covered with fine growth- 



stnae and excessively fine granules. Last whorl convex, strongly attenuated towards its base. 



Aperture obliquely oblong, sharply angular above, ending below in a short, compressed, gut- 



tome broken, probably with a wide, shallow sinus, columellar margin concave, 



with a thin layer of enamel.
