In Mr. Stutchbury's collection there is a curious diseased specimen of 

 this species: the shell is angulated in the middle, and the margin is 

 rounded and scarcely denticulated, except in the front, which exhibits 

 the short brown lines as in the type specimens ; but the peculiarity con- 

 sists in the dark spot, usually placed on the centre of each side, bemg 

 diffused over nearly the whole base, and especially over the lips of the 

 mouth, which are of a black purple colour and very obscurely toothed ; 

 the back nearly resembles the type.

Shell livid white, with very obscure indications of the opaque white 

 spots only to be seen in peculiar directions. I first mistook this variety 

 for a worn specimen of C. eburnea; but I have since seen other speci- 

 mens, especially in the rich cabinet of Mr. Broderip, which show its true 

 place to be with this species.
