It is from the characters of the animal rather than those 

 of the shell that the distinctness of this species must be 

 deduced. For the shell only differs in the smallness of

 depression of its body, and the greater nari-owness, and 

 perhaps flatness, of that portion of the final whorl which 

 flanks the aperture on the left. 



Montaffu described his animal as haviny 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 

 the mantle with a sinus ; the tentacula two, long and fili- 

 form, with two black eyes placed at their external bases, 

 and conspicuously visible through the transparency of the 

 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 

 colour, and the long and slender tentacles. 



Except tliat the dark colour runs into cloud-like or 

 patchy markings, we do not see much distinction between
