Gill-opening continued forward to bejlow the upper angle 

 of the preopercle. Humeral process not reaching the tip 

 of the pectoral spine by about an orbital diameter, its sur- 

 face with short sharp spines, a series of which near the 

 lower margin, is enlarged. Lateral scutes very high, cov- 

 ering almost the entire sides, those above the first anal ray 

 highest, If in the head, those on the caudal peduncle meet- 

 ing the scutes of the other side above and below; each lat- 

 eral scute posterior to the dorsal plate has a median hook 

 and 5-14 smaller spines above and below it. 



Basal half of the caudal rays with about five series of 

 small spines. 



Distance of the dorsal fin from the snout 2:^ in the length; 

 dorsal spine If in the length of the head; its posterior 

 margin smooth, its sides and anterior margin with many 

 short spines, a smooth groove between the spines of the 

 sides and front margin. Distance between dorsal and adi- 

 pose fins 3^ in the length; adipose fin oval, as long as the 

 dorsal fin without the spine. 



Caudal rounded, two in the head. 



Anal rounded, the central rays the highest, as high as 

 the length of the caudal. 



Ventrals not reaching the anal, 2 in the head. 



Pectoral spine strong, not reaching the ventral fins; its 

 lower surface bluntly granular, its upper with short teeth 

 like those on the humeral process, both margins finely 

 serrate. 



Brown, marked with white; a white lateral band not as 

 wide as the eye; a median series of white spots on 

 the back; ventral surface and sides of the head irregularly 

 spotted with white; top of the head with a median, inter- 

 rupted light band; dorsal, pectoral and ventral fins spotted 

 and marbled with brown and white; posterior margin of 

 the adipose white; caudal and anal fins with undulating- 

 cross-bars of white and brown. Barbels annulated with 

 brown and white.
