A second band from corner of mouth, touching lower border of eye, widened on operculum. Two similar bands below it, parallel with each other and with the upper one, running from chin, the first to base of pectorals, the lower one to above base of ventrals. Body with indications of darker lines along the longitudinal rows of scales. Dorsal and anal grayish, with a white edge and brownish oblique bars. Caudal brownish, with vertical bars, the distal part white in this way, that the outer rays are white for their distal half, the following rays gradually with less white, so that the inner most rays have only a white tip. Pectorals and ventrals hyaline. Males recognized by the grey-looking head when seen in natural light. Body with lined pattern until female stage. Males with orange spots along scale rows.

A posterior canine at corner of mouth. Head naked, exception above, where the scales begin above hinder part of eye. About 15 rows of scales before dorsal, the anterior ones much smaller than those of the body. Similar small scales on thorax, immediately behind isthmus. Dorsal spines feeble, but stiff and pungent. First spine equal to eye, last spine not quite twice eye. Soft dorsal higher than spinous part, longer ray equal to snout. Dorsal pointed behind. First anal spine very small, third longest, somewhat longer than eye. Anal spine stiff and pungent. soft anal similar to soft dorsal. Pectorals and ventrals, which have the first ray somewhat produced, sub equal, as long as head without snout. Caudal rounded. Least height of caudal peduncle equal to post orbital part of head.
