Shell oblong elliptical, nearly cylindrical, blueish white, very 

 obscurely banded, ornaroeated with fulvous lines, forming a beau- 

 tiful kind of net-work, leaving angular meshes; the dorsal line is 

 simple, straight, nearly central ; the edge is slightly thickened, 

 rounded, yellowish, with small blackish spots, slightly produced 

 at the extremities ; the base is flat with a small depression shelving 

 towards the aperture, on the middle of the inner lip; the aperture is 

 linear, rather broader at the front extremity ; the teeth are small, 

 rather close, pale brown ; columella plaited deep, front concave, 

 spire conical, covered with the margin, inside purplish; axis lj, 

 diameter f of an inch. 



Is remarkably like C. arabica in marking, but may be always 

 distinguished from it by its rounded sides, subcylindrical form, 

 and small teeth.
