Described from thi-ee specimens taken at Laredo Bay (with a 

 nmnber of very young specimens) and five from Sandy Point, in the 

 Straits of Magellan, the largest individual being 95 mm. in total 

 length. 



Head 3| in length to })ase of caudal (0.29 to 0.32 of body length), 

 depth 4f ; eye 4 in head (0.07 to 0.075); snout 3f ; length of maxil- 

 lary 21 (0.11 to 0.12); of mandible 2^ (0.12 to 0.14); width of inter- 

 orbital space 5| (0.045 to 0.055); length of pectoral IJ (0.19 to 0.23); 

 of ventral 1| (0.19 to 0.21); least depth of caudal peduncle 3 J (0.09 

 to 0.095); length of combined dorsal bases If in body (0.63 to 0.68); 

 of anal fin 2; D. V (or IV), 32 (or 33); A. 29 (or 2S); pectoral rays 

 20; scales with pores in upper lateral hue 40; in lower 6; in lateral 

 series 52 (49 to 54); in transverse series 5 + 15 (18 to 21); gill rakers 

 8+12. 



Head narrow above, strongly arched, its width less than its depth 

 at occiput; body compressed, its width one and one-third times in 

 depth at pectoral bases; maxillary ending under center of eye; dis- 

 tance from eye to nearest point on hne of occiput less than diameter 

 of eye (more in Notothenia sima) ; breadth of velar fold from tip of 

 lower jaw equal to two-thirds eye diameter; teeth above in two or 

 three rows anteriorly, three or four below; interopercle evenly 

 exposed throughout; jaws nearly equal; upper hmb of preopercle 

 inclined backward as it passes to angle; gill rakers short. 



Dorsal inserted slightly before base of pectoral; distance from last 

 ray to end of fleshy part of peduncle one-third least depth of latter; 

 last dorsal ray above third from last of anal; first dorsal not as high 

 as first rays of second dorsal, which are higher than last of same fin; 

 anal lower but similar to second dorsal; ventrals reaching anus; 

 caudal and pectorals rounded. 



Upper lateral line ending below last dorsal ray; lower commencing 

 immediately before its termination, very short. 



Scales absent on cheeks and opercles save narrow upper parts; 

 interorbital space completely naked, no buried scale between anterior 

 edges of eyes; those between occiput a,nd dorsal very small and 

 buried; scales apparently lacking in space between ventrals and 

 gill opening. 



Color dark; two clear streaks, separated by a narrow dark streak, 

 running obhquely back and downward from suborbital; a dark blotch 

 above these below posterior border of eye; ventrals dark, with faint
