diagnosa |
Head and body generally dark brownish when fresh. Two indistinct oblique dark bands on body, the first descending from the nape to behind the pectoral fin; the second from base of anterior 2nd or 3rd dorsal fin spines and soft dorsal fin base, curving backward thru the lateral line to soft anal fin and caudal peduncle. Maxillary scales absent. Eye diameter greater than one quarter of the head length. Ten pores on and behind the chin; often with slitlike pores posteriorly. Fleshy lower lip with a cluster of very short dense papillae. At the origin of the dorsal fin is a procumbent spinelike process (exposed tip of first pterygiophore) (Ref. 36944). |
