In this specimen the nucleus was of a lovely bright carmine color. This form, which is probably peculiar to deep water, may take the varietal name of carminura. It has seven whorls beside the nucleus, of a lemonade color, with nine ribs on the penultimate whorl, rather straighter than in C. thea and less swollen on the periphery. Lon. 11.5, lat. 4.0 mm. The Barbados specimens appear to be of the same sort, but are dead and faded.
