Head and body depressed, greatest body depth near posterior margin of supraoccipital. Caudal peduncle deep, compressed posteriorly. Dorsal profile of head ascending in arc to just behind supraoccipital and then descending to dorsal fin. From the dorsal-fin origin descending straight or in slightly concave arc to caudal fin. Ventral profile flat to from tip of snout to pelvic-fin insertions, from there, in concave arc to base of caudal fin.
