This was formerly esteemed by us as a form of C. marqnesa, Gaslcoin, of 

 the variety b. figured in Reeve, Conch. Icon., f. 217, and so 

 catalogued both in the Bombay list'^', and the enumeration of the 

 Mollusca of the Persian Gulf and Ara])ian Sea.'" 



Last year it was examined by Mr. Stephen Pace, who considers it quite 

 distinct, and worthy of a specific name. We have only seen two or three 

 examples, which, however, show no tendency to variation, and are identical 

 both in form, marking, nnd colour.
