There are three peculiarities of chai-acter in this species 

 which distuiguish it in an eminent degree from any other. 

 The first consists of a necklace-like row of small spinous 

 nodules just within the base of the spire ; the second 

 feature of interest is the dorsal bands of articulated semilu- 

 nar spots, which are presented in all stages of growth; and 

 the third is that of a row of spinous nodules upon the 

 ttattened surface of the outer lip. In foi-m the C. spinosa 

 has some general resemblance with the C.Jlamniea, but it 

 is a shell of much lighter growth and has no indication of 

 any tubercles.

M. Kiener has \ery tridy indicated these to be varieties 

 of the same species, the latter being of a very thick 

 swollen callous gTOwth, plicately tubereled round the 

 upper part, but agreeing in the minutest detail \\-ith tin- 

 former. Both are from the same locality.
