metre ; the interstices with fine growth-lines, which are reticulated 

 by fine microscopic spiral lines extending over all the whorls. Colour 

 horny, with radiate brown streaks, which usually form zigzag lines at 

 the periphery, flowing more or less together. The colour-markings 

 are very variable ; sometimes there are only a few broad brown streaks 

 on the upper side. Spire flat. Protoconch of 1| spirally striated 

 convex whorls. Whorls 4, the last two rapidly increasing, slightly 

 convex, the last not descending, periphery rounded ; base convex. 

 Suture not deep. Aperture slightly oblique, rotundly lunate. Pcri- 

 stome acute, straight, margins approximating. C 'olwnella short, arcuate, 

 not reflexed. Umbilicus conical, almost one-third of the greatest dia- 

 meter. 



Diameter Maj., 2-75 mm. ; niin., 2-6 mm. : height, 1 mm. 



Jaw membranous, arcuate, vertically plaited. 



Radula' having the formula 100x7 + 4+1 + 4+7. Central and 

 lateral teeth tricuspid ; marginals tridentate, the median tooth being 

 the largest.

Animal limaciform, minute, black all over, with subcentral visceral 

 hump, the greater part of the viscera protected by a shell, which in 

 turn is partly covered by the mantle. Most likely in the living animal 

 the mantle covers the whole of the shell. All the tentacles are re- 

 tracted in the spirit specimen at my disposal. Neck, sides, and tail 

 rugose, 3 longitudinal grooves on the neck : mantle smooth, minutely 

 punctured. Sole undivided, with slight transverse rugse, separated 

 from the foot by a double pedal line. Genital orifice behind the right 

 tentacles ; pulmonary orifice on the right anterior side of the mantle, 

 ending in a short distal slit ; anal orifice on the right side, just 

 below the middle of the visceral lump. Tail rounded, with a mucous 

 poro.
