Description
Size: 25.5 - 40 cm SL

Color: In alcohol specimens yellowish white to reddish brown, with three large ocelli, one below lateral line just at end of its curve, a second one more posteriorly between lateral line and anal and a third one above the second, between lateral line and second one. Each ocellus consists of two dark brown round blotches, each surrounded by chalk-white dots, the whole surrounded at some distance by a brown ring, which sometimes too is freckled with white. Indistinct brown rings scattered on body, dorsal, anal and caudal. Caudal and left pectoral variegated with dark brown.

Elongate, dorsal profile ascending in an arched line above eye. Height 2-2.3, 2.4-2.7 in length with caudal. Head 3.3-3.4, 4-4.1 in length with caudal. Eyes 3.9-5.7, nearly equal, above each other, separated by a very narrow elevated bony ridge, longer than snout, 2-2.5 in postorbital part of head. Eyelid with a tentacle in some specimens. Maxillary scaly on coloured side, reaching beyond middle of eye or not so far, 2.1-2.5 in head. Pointed, rather weak, distant canines in both jaws, the anterior ones of upper jaw somewhat larger. Origin of dorsal beginning on blind side, above or somewhat behind posterior nostril. A line connecting both reaches anterior half of maxillary. Dorsal and anal rays simple, scaly. The subposterior rays the longest. Origin of anal above or somewhat before vertical through hindborder of operculum. Praeanal spine generally inconspicuous, sometimes piercing the skin. Caudal bluntly pointed. Scales ctenoid on colored sides, in old specimens the scales have only a thickened rough patch at hindborder, cycloid on blind side, covering the head with exception of the snout. Top of curve of lateral line separated by about 17-18 scales from dorsal profile, its forward prolongation reaches dorsal profile at 7th dorsal ray. Left pectoral somewhat more or less than postorbital part of head, right one equal to or shorter than snout and eye. Ventrals equal to distance between anterior nostril and hindborder of eye. Gillrakers palmate, as long as broad, dentated round their free margin, 9-10 on lower branch of first arch. Teeth in both jaws small, without strong canines. Gill rakers palmate, as broad as long. Two to four large double ocelli on body. Dorsal spines (total): 0 - 0, Dorsal soft rays (total): 72 - 78, Anal spines: 0, Anal soft rays: 56 - 63, Vertebrae: 36.
