 of the shell that the distinctness of this species mnst be

 perhaps flatness, of that portion of the final whorl which 

 flanks the aperture on the left. 



Montagu described his animal as having a suborbicular 

 depressed body, convex above, of a yellowish colour, 

 speckled with bright brimstone, and marked with round 

 particles, interspersed with a few black spots ; the front of

 covering lamina; the sustentaculum oval. He mentions a 

 variety destitute of black spots, and having the yellow 

 markings most conspicuous. He lays much stress on the
