specimens for more than twenty years lying unnamed in my collection

_ 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 lip exteriorly variegated, inner 
with small white ridges, and on the columellar margin are several raised 
short white ridges. 
The similarity to grains of maize (Zi#) suggested the trivial name.

A very few specimens, and those mostly imperfect, have occurred of 
this little Mctrella. Its whorls, seven in number, and quite smooth, 
are ornamented with flame-like zigzag markings at the sutures, and 
extending over the whorls, also ornamented with opaque white marks 
and blotches. In the last whorl there is a pale median transverse line
