Elongate, slender, niucli compressed, deep in front of dorsal and anal; 

 greatest depth equal length of caudal, little less than one-third of the total 

 length. Length of head hardly one-fourth of the total. Snout blunt, slightly- 

 concave in upper outline as seen from the side, two and one-third times as 

 long as the eye. Eye large, three and one-half times in the head. Gill open- 

 ing as wide as the eye, oblique, below the orbit, above the base of the pectoral. 

 Lower edge of breast and belly tliin, blade-like, very convex. Squamation 

 villiform. Both dorsal spines above the orbit ; anterior strong, long, more 

 than twice the length of the eye, with four series of sharp hooks directed 

 toward the base, the anterior two of which are close together; second spine 

 very small, close to the first. Second dorsal and anal opposed, latter originat- 

 ing by several rays farther forward. Caudal pedicel slender ; fin long, pencil- 

 shaped, wide. Pelvic bone rather rigid; pelvic spine continuous with the 

 bone, immovable. Pectorals ^mall, broad, and short, as long as the eye, 

 longer in their upper halves. 



Light yellowish or olivaceous brown, darker on head and back; with trans- 

 verse blotches of brown on forehead, first spine, and back; with irregular 

 subvertical series of brown blotches on flanks and tail, arranged in pairs, the 

 first pair being below the space between first dorsal and second, the second 

 pair below the anterior twelve or fourteen rays of the soft dorsal, and the 

 third farther back toward the end of the fin, while the fourth is on the caudal 

 pedicel. The spots on the caudal are comparatively large ; the tip of the fin 

 is dark.
