vent, 1.2 in head; pectoral moderately small, failing to reach tip of 

 ventral, the rays all simple, the fourth and fifth (from above) longest, 

 about as long as head, 3.6 in length. 



Color pale, with brown markings of various sizes and shapes on 

 back and sides; a rather definite pale streak on side in the usual 

 position of the lateral line when present; a less distinct pale streak 

 lower down on side; an irregular brown bar on and under anterior 

 spines of dorsal; another broader one on middle of spinous part of 

 dorsal; a third one on last dorsal spine; and a fourth one on soft 

 dorsal; caudal brownish distally; anal and pectoral largely brownish; 

 ventral with an indefinite dark bar on distal half. 



This species is not represented in the Peruvian collections in the 

 U. S. National Museum. In fact, it does not seem to have been 

 taken on the coast of Peru by recent collectors. The description is 

 based on a specimen with a slightly deformed caudal fin, about 

 185 mm. (165 mm. to base of caudal) long, taken off Montevideo, 

 Uruguay (at lat. 36° S., long. 54° W.) at a depth of about 28 fathoms. 

 Norman (1937, p. 127) reported specimens in the British Museum 

 from the "coast of Chile and Peru," which he considered identical 

 with others from both the west and east coasts of Patagonia. 



Range. — "Both coasts of southern South America, from Uruguay 

 to Peru" (Norman, 1937, p. 127). 



Family COTTIDAE: Sculpins 



Body elongate, round or compressed; head usually broad and 

 depressed, though occasionally somewhat compressed (as in the form 

 herein described), often armed with spines, though occasionally 

 entirely unarmed; eyes placed high; teeth small, pointed, in bands 

 on the jaws, and often on vomer and palatines; premaxillaries pro- 

 tractile; maxillary without a supplemental bone; gills three and a 

 half or four; gill membranes connected, often joined to isthmus; 

 lateral fine present, simple or chainhke; scales present or absent, 

 often replaced by prickles or bony plates; dorsal fins separate, the 

 first consisting entirely of spines; anal fin similar to second dorsal, 

 composed entirely of soft rays; ventral fins thoracic, rarely wanting, 

 usually with one spine and three to five soft rays; pectorals large, 

 the rays mostly simple. 



This family is represented by a single genus and species in the 

 collections studied; both new to the known fauna of Peru.
