86 Annals of the Carnegie Museum. 



Head depressed, without ridges; snout broadly rounded, margined 

 with short, thick bristles; interopercle with about eight spines, the 

 longest in the smaller specimen, a female from Santander, being 

 about one-third as long as the head. The longer ones are lost from 

 the larger males; last dorsal ray joined at the base only to the scute 

 following it; caudal slightly, but very obliquely, emarginate; pec- 

 toral spine in the male reaching beyond middle of ventrals, shorter in 

 the female. Scutes spinulose, not carinate; lower surfaces of head 

 and body naked. Adult nearly uniformly dark brown, all the fins 

 with obscure spots on the rays; caudal in the young with two or more 

 cross-bars. 



Named in honor of Mr. Andrew Carnegie, the founder of the 

 Carnegie Museum.
