caual. Outer Up contracted and very slightly curved above, very 

 patulous where the bend comes, and below this direct and 

 oblique ; it has about 10 small teeth witliin, of which the highest 

 is remote from the top, and is larger than the others ; just at this 

 point is a slight open false sinus. Inner lip : there is a thin 

 glaze on the body, the line across which is very straight, as is also 

 the line down the pillar where the glaze forms a projecting border 

 (without teeth), which runs out sharp and narrow to the very 

 point ; the point of the pillar is very obliquely cut off with a 

 twist ; the pillar itself is short, strong, and conical. H. 0"25. 

 B. 013. Penultimate whorl, height O'OS. Mouth, height O'll, 

 breadth 0-06.

SJiell. — Small, oval-oblong, glossy, white, with a short blunt 

 spire, a conical base, and a small oval mouth. Sculpture. Longi- 

 tudinals — lines of growth very faint. Spirals microscopic and 

 obsolete. Colour porcellaneous white, more or less transparent. 

 Spire short, convexly conical. Apej: bluntly rounded. Whorls 

 41, conical) barely convex, with a minute sharp scalar projection 

 below the suture. Suture minutely channellecl. Mouth oval, 

 pointed and channelled above, slightly narrowed below. Otcfer lip 

 sharp and thin, patulous ; below, it projects in a blunt point on 

 the right side, between which and the pillar is the broad, open, 

 shallow canal. Inner lip: there is a thick, narrow, irregular-edged 

 pad ; this in front coils round the pillar, which is bent, twisted, 

 short, truncated, and toothless. H. 015. B. Oil. Penultimate 

 whorl, height 0-06. Mouth, height 01, breadth 0-07. 



In general size and proportions this a good deal resembles O. 

 spreta, Gould ; but that is lower in the spire, the peripheral breadth 

 lies higher, the shell is more attenuated in front, the mouth is 

 longer, and the pillar is more defined by a pad crossed at the 

 point by two teeth.
