Color - In life the post-ocular stripe is yellow, not blue as had been suggested by B&R. The species also has a yellow medial bar on the snout starting at about the point of the least interorbital distance and running to nearly the upper jaw. This bar is often lost in preservation, but is visible in the material from Aves Island. The snout marking may or may not be visible in preserved specimens. (Colin 73)
