Head nearly 3 in length, 3 1/3 in length with caudal, pointed, its rostro-dorsal profile strongly sloping, rectilinear or slightly convex, scaly, only snout and jaws naked, about 14 oblique series of scales on checks, opercle unarmed, its triangular flap produced, praeopercle superiorly with a pointed flat spine. Eye 4 in head, nearly half its diameter longer than interorbital space, longer than snout. Jaws equal, reaching, behind eye. Cleft of mouth rather wide, slightly oblique. Teeth in jaws pluriseriate, the anterior ones slightly longer, canines or caninoids are wanting, on vomer and palatines patches of small teeth. Scales ciliated, between upper corner of gillopening and caudal 48-50 transverse series of scales. Lateral line tubulate, beginning at that corner, its upper part runs parallel to the dorsal, separated from it by 4 scales and terminates below the middle of the soft-rayed dorsal, lower lateral line originating before the termination of the upper one, separated from it by six scales. Dorsal commencing above base of pectorals, with 7 pungent, distant, subequal spines, much lower than the rays, their membrane deeply incised, covered with scales, the soft-rayed portion, with 19-20 branched rays, rounded, not half as high as height of body, scaly at its base. Anal of similar form and structure, with three pungent spines of which the middle one is the longest and strongest. Caudal rounded, equals about the postocular part of the head and is slightly shorter than pectorals which are rounded and have the base densily scaled. Ventrals short, rounded, the third ray the longest.
