Eye 3J-4 in the snout, 8| in the head, 3 in the inter- 

 orbital; eye more superior than lateral. 



Maxillary barbels extending to posterior 4th of humeral 

 process; post-mentals to opposite the insertion of the inner 

 pectoral ray; mentals about f as long as the post-mentals. 



Snout pointed, its width at the rictus 2| in the head. 

 Upper jaw projecting; teeth villiform, the intermaxillary 

 band about six times as wide as deep. 



Gill opening extending to a point midway between upper 

 angle of preopercle and the eye. 



Lateral scutes high, the third hook-bearing one the high- 

 est, 1| in the length of the head, the sciites decreasing in 

 height to the last, the median hooks increasing in size 

 to the caudal peduncle, the exposed surface of those in 

 front of the peduncle thickly set with small spines. 

 Accessory rays of the caudal fin ossified, the anterior one 

 forming a small plate. Exposed part of the skin verrucose. 



Humeral process narrow, tapering backward, reaching a 

 little beyond the middle of the pectoral spine. 



Distance of the dorsal fin from the snout about 2| in the 

 length. Dorsal and pectoral spines with the sides deeply 

 furrowed, both margins serrate; the serration of the poste- 

 rior margin of the dorsal spine reduced to a few spines. 

 Adipose fin low, merging into the profile of the back ante- 

 riorly. 



Caudal emarginate, 5 in the length. 



Anal high, rounded, first ray highest, 2 in the head. 



Ventral as high as the anal fin. 



Pectoral spine not quite reaching the ventral fins. Pec- 

 toral pore minute. 



Fins spotted with brown. 



Head 4; depth 5; Lat. 1. 18; D. I, 6; A. (injured?) 6: 

 V. 6; P. I, 9.
