REPORT ON THE GASTEROPODA. 231 



but sharper furrow which runs out into a little prickle on the outer lip ; the upper part of 

 the body-whorl is buried in enamel, banded with alternate white, brown, and pale, the 

 succession of which colours up the spire makes it possible to count the whorls. Colour 

 fawn, banded with white and brown. Spire high and small. Apex small, bluntly rounded, 

 and white ; it is free from enamel. Whorls 6 ; the last is elongated, and a very little 

 tumid. Suture buried. Mouth narrowly oval, pointed above, truncated, and emarginate 

 in front. Outer lip flatly curved, thin, with a projecting point on the edge in front. 

 Inner lip slightly convex on the body, concave below ; a thick labial pad loads the twisted 

 pillar, fills the mouth above, spreads out on the body, and covers the spire. Operculum, 

 triangularly lanceolate, sharp-pointed above, with a terminal nucleus lying toward the 

 outer edge, feebly lineated, thin, yellow, with a dull gloss ; it quite fills the mouth of the 

 shell. H. 0-37 in. B. 0'17. Mouth, height 0'22, breadth 0-07. 



This species is narrower than any of the small Ancillas, and has at the same time all the appear- 

 ance of being full grown.
