Description
Size: 10-18.5 cm.

Color: In preserved specimens reddish brown on head and back, silvery below. Fins light yellowish. Membrane of pectorals bluish grey with white spots.

Height 3.5-4.4, 4.3-5.4 in length with caudal. Head 2.7-3, 3.3-3.6 in length with caudal. Eye 3.3-3.9, 1.5-1.9 in snout. Interorbital space concave, 1.2-1.6 in eye. Mouth almost horizontal. Maxillary reaching to below front border of eye in large specimens, not so far in young ones. Villiform teeth in rather narrow bands in the jaws and in a narrow band on vomer. No palatine teeth. Preorbitals produced beyond upper jaw, in young ones with a large horizontal spine at their end, following by about 12 spines gradually decreasing in length to the median line and with a great number of minute spines along their lower border. In old specimens the large spines get blunter and the upper profile of the preorbital process is therefore less pointed. Nostrils at some distance from each other, the posterior one with a short tube. Supraorbital ridge with two blunt spines anteriorly and another one at the end, followed by a transverse groove which is indistinct in vey large specimens. Superior postorbital ridge with a number of minute spines and a larger blunt spine at the end, inferior postorbital ridge with a number of minute spines, better developed in old than in young specimens, interrupted in the middle and with a large blunt spine at the posterior end of both part of both parts. Suborbital ridge poorly developed, serrated or granulated, ending in a short spine at preopercular edge, this spine indistinct in large specimens. A well developed flat opercular spine, and a long and pointed humeral spine. Origin of first dorsal slightly behind gill opening. Front border of first spine and upper part of front border of second spine serrated. Second spine longest, about equal to half length of head. Last dorsal spine minute. Anterior rays of second dorsal as long as fifth dorsal spine, the following rays slightly decreasing in length to the last. Anal somewhat lower than second dorsal, the anterior rays as long as sixth dorsal spine. Median pectoral rays branched, the other simple. Pectorals almost as long as head or shorter, well reaching on anal. The first of the three free rays longer than the second, the third shortest. Ventrals as long as snout and eye. Caudal truncate. Scales of back ctenoid, those of sides and belly cycloid. Throat and breast without scales. About 6 or 7 rows of scales before origin of dorsal.
