slightly reflected ; pectinated by the strong carinas. Lahium, on a 

 plane with the labrum above, lower below ; joining the labrum with a 

 curve above ; much curved to the right, below well detached from the 

 penult whorl. TJmhilicuSy narrow and deep. Labral lamella, well 

 produced above and rather wide below. Operculum, moderately 

 concave in the middle, with a wide border on the labial side, which 

 is vertically grooved and again crossed by four or five raised horizontal 

 plaits : labral side with about eight short horizontal lamellae, about 

 four extending across the hollow, and a linguiform point at the lower 

 extremity of the labial side overlapping the labium. 



Height 0-072, greatest breadth 0*1, least breadth 0-074.

Form, depressed conic. Colour, pale horn or yellow. Sculpture, 

 1 7 strong spiral carinse with 1 fine intervening between each pair. On 

 the upper whorls 5 strong with 1 fine intervening. Spire, moderately 

 elevated, with straight outlines. Whorls, A\, moderately rounded, 

 with a light suture. Aperture, scarcely separated from the body- 

 whorl, more than a semicircle, large, rather expanded and depressed 

 below. Lahrum, very slightly produced above, strongly and promi- 

 nently pectinated by the strong carinse, imbricated in those round 

 the periphery, white and shining. Labium, slightly rounded into the 

 labrum above, and on the right below ; very slightly reflected ; on a 

 plane with the labrum above, lower below ; very slightly detached 

 from the body- whorl. Umbilicus, deep and narrow. Lahral lamella, 

 sharp and very slightly produced. Operculum, moderately concave, 

 with large coarse granulations on the upper part of the labial side, 

 slightly lamellated horizontally ; lower portion of labial side broad 

 and spreading over the labium, with a deep groove, and terminating 

 with a broad uplifted linguiform plait, which is distinct from the 

 spreading upper portion.

 with rather concave outlines. Apex, rather acute. Whorls, A\, mo- 

 derately rounded, with a slight suture. Aperture, slightly spreading 

 about the periphery to below ; subsemicircular. Labrum, very slightly 

 produced above, more so below ; broadly detached from the body- 

 whorl, strongly pectinated by the spiral carinse. Labium, well de-
