Shell small, ovate, white, with flattened whorls, a subscalar spire, 

 a very blunt apex, a pear-shaped smallish mouth, and a very slight 

 tooth on the pillar. Sculpture: Longitudinals there are very 

 faint hair-like lines of growth. Spirals there are on the last whorl 

 about 20, on the penultimate whorl about 8 rather strong and equal 

 furrows stippled with roundish oval pits; they become more crowded 

 and weaker toward the middle of the base ; just below the suture the 

 first furrow is minutely and slightly beaded, and it with the next 

 one or two is strong and these are crowded ; the flat surface which 

 parts them is somewhat broader than the furrows. Color translu- 

 cent and subglossy white. Spire conical, high, scarcely scalar. 

 Apex blunt and truncated ; the extreme tip is a very little inverted. 

 Whorls 5, very slightly shouldered just below the suture; round 

 the top there is a very feeble constriction ; below this the whorl i& 

 conical, and in profile flat on the sides ; the last whorl is a very little 

 tumid with a produced base. Suture very little oblique, strong >h 

 and well marked, but not channelled. Mouth pear-shaped, pointed 

 above, a little oblique in direction, patulous or very slightly guttered 

 in front of the pillar point. Outer lip straight and parallel to the 

 . and a little contracted above, arched and patulous in front. 

 Inner lip slightly convex on the body, on which there is a thin but 

 distinct L_ r la/e with a defined edge; there is a slight angulation at the 

 junction of the body and the pillar, near the top of which is a vcrv 

 faint t-M.tli Amounting to no more than a Blight swelling ; the pillar 

 toelf U very slightly oblique, and is straight, narrow with a sharp 

 edge behind which is a very slight and shallow furrow. Alt. 0'16 

 in.; diain. <H. Penultimate whorl height 0'04. Mouth height 

 0-08, breadth 0'05. ( Wat*.).
