one of which is at each end of the dorsal line, and one on each 

 side, the front one heing on the right side, and the hinder on that 

 next the spire, or the left ; the longitudinal strias are narrow, 

 smooth, and very close together ; the dorsal line is deep and nar- 

 row ; the base is convex ; the mouth is linear, curved at both ends, 

 as long as the shell and the covered rather convex spire ; the 

 outer lip is thickened on the outside, and margined .; the teeth 

 are very small, and close together. 



Length ^, breadth ^-^ of an inch. 



This shell is very rarely destitute of the four small dorsal spots. 

 When young it is of a most beautiful purplish rose colour, quite 

 smooth, and polished, with a few very obscure concentric wrin- 

 kles. 



I have seen this shell called in some cabinets C, Pulex of 

 Solander's MSS. ; but the description given by Dillwyn of that 

 species does not agree with it in any respect : it answers very well 

 for the species found in the Mediterranean Sea. 



This shell may perhaps be C. pediculus ^. Born, Mus. Find.
