aperture narrow, much curved at the posterior third of its length, 
the other two-thirds nearly straight; teeth white, distinct, even, 
about twenty-seven on the outer side, extending but slightly over 
the lip; on the columellar side about twenty-four, broader at the 
anterior end, while along the continued edge of the aperture to its 
posterior extremity are mere indications of teeth; columellar sulcus 
deep and broad, not extending beyond the more prominent teeth ; 
base broad and flat, its entire circumference of an uniform dark, 
reddish-brown colour, or spots of a similar colour, the colour lessen- 
ing in intensity towards the middle portion of the base, which is 
white, as is also the interior of the shell ; margins project, especially 
that of the lip: extremities produced, the posterior forming sharp or 
thin edges, and extending much upwards ; that on the columellar side 
terminating at the apex of the spire; the anterior extremities also 
thin, and the channel upright. 
I have seen this shell only in the adult state. It has no general 
characteristic in common with any known species; the extremities 
however have much similitude to Cyprea Scottii; but it is a much 
shorter, more gibbous, heavier and thicker shell.

Shell ovate, anterior end rather pointed, the posterior and middle 
very gibbous ; of a cream-colour, a few fulvous spots are irregularly 
scattered over the entire back and sides of the shell, apparently the 
commencement of the deposition of colouring-matter ; base flat and 
very broad, on the outer edges are discrete fulvous brown spots, the 
rest of the base, the teeth, and the interior of the shell are of a clear 
cream-colour; aperture wide, spiral; columella gibbous posteriorly, 
a slight sulcus at the anterior end; teeth form, on the columellar 
side, a single angular serrated edge, about twenty in number, wide 
apart and not very prominent; on the other side they are more 
regular and even, extending, slightly prominent, half across the lip ; 
they are smaller and more perfect towards the anterior extremity, 
and about twenty-nine in number ; the extremities are produced, flat, 
form a broad channel, passing upwards at the posterior end of the 
shell, and terminate at the outer side of the apex of the spire; the 
anterior extremities are much less produced, and converge, forming a
