soft rays: 23 - 27. Three prominent diagonal grooves running from below and behind mouth nearly to gill opening; light brownish gray with rows of dark brown spots on body; grooves on head dark brown; caudal fin pale with orange-red upper and lower borders and a large orange-red crescent posteriorly (Ref. 13442).
