Description of very numerous specimens (250) from Sandy Point, 

 Port Churruca, Gregory Bay, and Laredo Bay in the Straits of 

 Magellan; Otter Bay in Smyth Channel; Port Grappler; and Mayne 

 Harbor, Patagonia. Specimens of this species were taken from the 

 stomach of a "hake" in Borja Bay in the Straits of Magellan. A 

 mature specimen 240 mm. in total length is used as the type of the 

 description, with the range of 20 specimens given m parentheses. 



Head, 3f in body length to base of caudal (0.30 to 0.33) ; depth, 5 

 (0.18 to 0.20); eye, 4f in head (0.055 to 0.07); snout, 3^ (0.07 to 0.09); 

 maxillary, 2* (0.095 to 0.13); mandible, 2^^ (0.115 to 0.145); width 

 of interorbital space, 6 (0.04 to 0.055); length of pectoral, 1| (0.22 to 

 0.24); of ventral, 1§ (0.17 to 0.20); depth of caudal peduncle, 3| (0.07 

 to 0.08); length of combined dorsal bases, 1| in body; of anal base, 2; 

 D. (VI or) VII, 33 (32 to 34); A. (32 or) 33; pectoral rays, 24; scales 

 with pores in upper lateral line 48, in lower 11 (41 to 49 + 6 to 13); 

 scales in longitudinal series, 77 (69 to 80) ; in a transverse series from 

 origin of anal obliquely forward and upward 7 + 22; between insertion 

 of dorsal and line of occiput, 17 (15 to 19) ; giU rakers, 8+14 (21 to 24). 



Head slightly depressed, with wide mouth, shghtly cottoid in 

 shape, its width a trifle greater than its depth; hps thick; interor- 

 bital space narrow, flat, or slightly concave; lower jaw longest, pro- 

 jecting in front of upper; velar fold measured from tip of lower jaw 

 two-thirds of, or ec{ual to, eye diameter; teeth in a loose double row, 

 in front enlarged somewhat, behind small; upper surface of eyeball 

 exposed and pigmented; upper limb of preopercle inchned back- 

 ward toward angle; gill rakers short. 



First dorsal inserted above pectoral base, comiected shghtly at 

 base by membrane with first ray of second, from which its last spine 

 is as far distant as the space between two spines; second dorsal ter- 

 minates above third from last anal ray; depth of caudal peduncle 

 greater than distance from last anal ray to last of muscular part of 

 caudal peduncle; longest dorsal spine 3 m head; rays subequal, 3| in 

 head; anal similar, rays 4 in head, the posterior rays somewhat 

 longer; ventrals extendmg nearly to anus; pectorals rounded; caudal 

 margin convex. 



Upper lateral line ending five scales before end of muscular part of 

 tail; lower line usually short and but slightly overlapped by the upper. 



Scales on dorsal surface of head and occiput in adults frequently 



appearing nonimbricated, those on cheeks concealed; scales not 



always rough to the touch except on belly and lower side of flanks, 



and never roughly ctenoid as in Notothenia longipes; scales present
