broad, of a pale greyish purple or flesh-colour, with three 

 dark spots on the ridge of the back. It may be at once dis- 

 tinguished from C. sulcata, by its not having any dorsal 

 groove, or more than three dorsal spots, and these are some- 

 times wanting. Mr. Montagu in his Supplement has justly 

 remarked that C. bullata is this species in the adolescent 

 state, and Bulla diaphana the first and most imperfectly 

 formed shell.

Shell near an inch long, and rather more than two thirds as 

 broad ; white with a slight tinge of flesh-colour, much de- 

 pressed, and marked on the upper part with raised tubercles, 

 and obsolete irregular somewhat undulated ribs. The two 

 extremities appear rather truncated, and slightly indented by 

 the aperture ; the base is broad, convex, and transversely 

 ribbed through its whole breadth. All the specimens which 

 1 have seen have had two holes through them, and Lamarck 

 says they are strung together, and used as necklaces by the 

 natives of Otaheite. It is a much flatter and broader shell 

 than C. Nucleus.
