Discussion

C. bahamensis is similar to C. mindanus, C. flavescens and C. puncticulatus . C. mindanus can be distinguished by its conical last whorl, the straight outline of the spire, deep concave sutural ramps and the lack of tubercles on the teleoconch whorls. C. flavescens has a narrower last whorl with almost straight outline; its spire has a straight outline and concave sutural ramps. C. puncticulatus is smaller with a bluish violet ground colour (white in the population known as C. columba) and often a brown pattern, it has an ovately shaped last whorl and a carinate shoulder, its anterior end is more distinctly twisted.
