Base of first dorsal 2.3 (2.0-2.5) in head; fin of 8 (8-9) spines; first 

 spine 1.5 (1.3-1.7) in fourth or fifth spine, which is longest, being 2.6 

 (2.3-3.0) in head. Base of second dorsal 1.1 (1.0-1.1) in head; fin 

 of 16 (16-17) rays; first ray 1.9 (1.5-2.3) in sixth ray, which is longest, 

 being 2.0 (1.9-2.1) in head. Anal origui under second or third 

 dorsal ra}'', its posterior end under fourth ray from end of second dor- 

 sal; base of fin 1.5 (1.4-1.6) in head; fin of 11 (10-12) rays; first 

 ray 1.8 (1.6-1.9) in sixth or seventh ray, which is longest, being 2.8 

 (2.6-2.9) in head. Pectoral base 3.1 (3.0-3.3) in head; fin of 17 

 (16-18) rays; longest ray 1.4 (1.4-1.5) in head. Pelvics extending 

 to or slightly beyond anus, their length 1.7 (1.7-1.9) in head. Caudal 

 with 8 (8-9) split rays; length of fin 1.4 (1.3-1.4) in head. 



A single series of 26 (23-28) large scales forming a band along 

 base of dorsal fins, having its origin under fifth or sixth dorsal spine 

 and extending on the dorsal surface of the caudal peduncle to or 

 almost to base of upper caudal rays. Each of these scales in the form 

 of a roughly oval, deeply embedded plate from which rises another 

 smaller strongly ctenoid plate inclined posteriorly. Lateral line 

 armed with 36 (34-37) deeply embedded scales in the form of short 

 tubes, their free posterior margins strongly ctenoid.
