Shell very small, subdiscoidal, umbilicated, closely and sharply 

 ribbed, cinereous with light brown, not shining. Sculpture : Proto- 

 conch with fine and close radial striae, the succeeding whorls with 

 rather close fine elevated and sharp riblets, 8 to 10 per millimetre ; 

 they are protractive at the suture, arcuate on reaching the periphery, 

 thence straight, lightly flexuous ; in some places the riblets are in- 

 equidistant ; interstices with fine growth-lines and obsolete micro- 

 scopic spiral lines. Colour cinereous, in some places rufous, with a 

 few pale-horny streaks. Spire flattish, very little raised. Protoconch 

 of 1 J convex turns. Whorls 4f , convex, regularly increasing, periphery 

 and base rounded. Suture impressed. Aperture slightly oblique, 

 rotuiidly lunate. Peristome thin, sharp, retracting towards the suture, 

 and forming a not very conspicuous sinus. Columclla very short, 

 arcuate. Inner lip not thickened and not reflexed ; parietal wall 

 with a broad shining glaze. Umbilicus broad, deep, showing all the 

 whorls, its diameter about one-third of the greatest diameter of the 

 shell. 



Diameter Maj.. 3 mm. ; min., 2-7 mm. : height, 1-5 mm. 



Animal unknown.

Hab. White Horse Hill, Hooker Valley, South Island ; among

Shell very small, subdiscoidal, umbilicated, not shining, thin and 

 fragile, radially finely costate, pale with fuscous streaks. Sculpture 

 consisting of close fine and sharp radial riblets, about 30 per milli- 

 metre, very little oblique on the protoconch, protractive on the follow- 

 ing whorls at the suture, then curving forward and becoming nearly 

 straight on the periphery and base ; interstices with fine growth-lines, 

 and excessively fine microscopic striae. Colour pale-horny with rather 

 distant fulvous streaks forming zigzag lines on the periphery and 

 base. Spire very little raised, flattish. Protoconch of If convex 

 whorls. Whorls 4|, slowly increasing, convex, periphery and base 

 rounded. Suture well impressed. Aperture slightly oblique, rotundly 

 lunate. Peristome acute, thin ; the outer lip distinctly advancing at 

 the periphery, retractive toward the suture, and forming a well-marked
