i. 56. 
Suen. of medium size, elongated ovate, somewhat angular in its 
contour, solid and coarse in structure, with coarse, irregular lines of 
growth, of a dingy white colour, and destitute of epidermis. Spire 
composed of five convex whorls, separated by a deep irregular suture. 
Aperture rather more than half the length of the shell, somewhat 
ovate-ear-shaped, the peristome very broadly revolute, white, some- 
what angular posteriorly, and a little narrower at the base of the colu- 
mella; the columellar fold largely developed. Umbilicus small. 
Length of axis one and three-fourths inches; breadth one inch. 
Inhabits the Feejee Islands. 
Ii is of the same type as B. malleatus and elobatus, but is smaller, 
more solid, and less elegant than its associates. Its destitution of 
colours and epidermis, and its very broad lip, with its angular out- 
lines, characterize it.
