of the Ge?ius Ancillaria. 281 



Shell, one inch and three-quarters long; oval, ventricose, and 

 somewhat fusiform, the spire being pointed, and nearly of the 

 same length with the aperture ; the base is also contracted. The 

 suture is marked by a slender, obtuse, carinated line: the body 

 whorl is flesh-coloured, and finely striated longitudinally ; having 

 on the upper part a slightly-thickened belt, margined below by an 

 impressed line ; the belt is continued on the spiral whorls, and is 

 marked by brown spots or blotches. At the base of the shell are 

 two thick belts, also brown ; above which are two parallel grooves, 

 forming two teeth at the base of the outer lip, and not one, as men- 

 tioned by Lamarck. The inside of the aperture is orange-brown : 

 the varix on the pillar slender, and deeply striated ; and the base 

 considerably emarginated.
