56 Mr. James Cosmo Melvill on 



years lying unnamed in my collection, and there are others, 

 likewise unnamed, in the British Museum. 



It is a conical, sharp-pointed little shell, acutely broad 

 in the middle, giving a quadrate appearance to its contour, 

 becoming rapidly attenuate at both ends. Round the 

 centre of the last whorl runs a conspicuous white median 

 band, formed of white transverse nodules, the rest of the 

 surface of the shell being nodulous, and variegated brown 

 and white. 



The mouth is triangular-ovate, outer Up exteriorly 

 variegated, inner with small white ridges, and on the colu- 

 mellar margin are several raised short white ridges. 



The similarity to grains of maize i^ia) suggested the 

 trivial name.

 the same locality. The shell is small, smooth, ornamented 

 with painting of narrow, usually continuous, but in some
