Ja.tr slender, slightly arcuated, with about 35 flat plaits, which 

 indent both margins. 



Radnla (Plate 1, fig. 11) having tin- formula 35+1 + 35. with 

 18 laterals in a large specimen. In smaller animals the number of 

 teeth is sometimes as few as 22, with 10 laterals. Central tooth 

 with the base narrower in front, longer than broad : refiexed 

 portion narrow, two-thirds the length of the base, with a minute 

 lateral cusp on each side, the mesocone moderate. Laterals with the 

 inner side of the reflexed portion sinuated, outer side with a short 

 broad emarginate process: the cutting-points longer than on the 

 central tooth. Marginals at first longer than broad, but near the 

 margin broader than long, the inner with a bidentate point : the 

 outer also with a bidentate point, and one or two smaller ones out- 

 side it.

Xli ell small, discoidal, perforated, radially ribbed, devoid of colour- 

 markings, not shining, semi transparent, thin and fragile. Sculpture : 

 Protoconch microscopically finely spirally lirate ; succeeding whorls 

 with strong, rather distant, almost straight radial riblets, about 9 per 

 millimetre, extending down to the perforation ; interstices with fine 

 growth-lines, reticulated by microscopic close spiral strise. Colour 

 light-horny, without any markings. Epidermis thin and membranous. 

 X / >i-re flat, very little raised. Protoconch of 1| lightly convex whorls. 

 Whorls 4| to 5, convex, regularly increasing, the last not descending, 

 and its periphery rounded ; base roundish. Suture impressed. Aper- 

 ture subvertical, lunar, considerably excavated by the penultimate- 

 whorl. Pcrislomc thin and sharp. The outer lip convex ; basal Up 

 straightened. Columclla very short and oblique. Inner Up slightly 

 callous, but little reflected above, broadly extended over the parietal 

 wall as a very thin white glaze. Umbilicus very narrow, about one- 

 tenth of the greatest diameter, quite open.
