Pyrgocythara albovittata (C. B. Adams, 1845)

Pyrgocythara albovittata (C. B. Adams, 1845)
There is a group of variously-banded Pyrgocythara species in SE Florida and the Caribbean-West Indies which includes this morph. C. B. Adams named some of the group, and his Pleurotoma albovittata (1845) is a less wave-worn match for the specimen illustrated below.
