Depth of body 3 to 4 in the length, length of head 3^ to 3! . Snout (except in young) 

 longer than eye, diameter of which is 3 (young) to 6 in length of head ; interorbital 

 width z\ to 3^. Jaws equal anteriorly; maxillary extending to below anterior \ or 

 anterior \ of eye ; teeth in one or two series anteriorly in both jaws, always uniserial 

 laterally ; no distinct canines ; a few imbricated scales behind the eye and on the upper 

 part of the operculum; upper surface of head naked, papillose; 10 to 13 gill-rakers on 

 lower part of anterior arch. Scales on body generally smooth; 50 to 60 in a lateral 

 longitudinal series; 36 to 46 tubular scales in upper lateral line, which ends below 

 posterior rays of dorsal, 6 to 14 in lower lateral line. Dorsal III— VI 1 29-31 ; longest 

 spine \ to f length of head. Anal 22-25 > length of base z\ to 2§ in that of fish (without 

 caudal). Pectoral f to f length of head, much longer than pelvics, which extend f to § 

 of the distance from their base to the vent. Caudal emarginate in young, becoming 

 truncate or even slightly rounded in adults ; caudal peduncle usually somewhat longer 

 than deep. Greyish olive above, becoming yellowish below; more or less distinct 

 longitudinal stripes or series of spots on the sides ; traces of oblique stripes below the 

 eye ; spinous dorsal dark ; soft dorsal dusky, sometimes reticulated, and with a narrow 

 pale margin; caudal, pectoral and pelvics usually more or less dusky. The young are 

 more silvery, especially on the lower parts of the head and body, and the fins are 

 much paler. 



Hab. Patagonia ; Falkland Islands ; Straits of Magellan ; coast of Chile, northwards 

 to Talcahuano; Kerguelen; New Zealand; Auckland Island; Campbell Island; 

 Macquarie Island. 



In addition to the above, Mr Bennett has sent 8 specimens (55-220 mm.) from 

 Stanley, Falkland Islands, taken in shallow water with hook or seine net. There are 

 also 15 specimens (40-350 mm.) in the British Museum collection from the Falklands, 

 Straits of Magellan, Kerguelen, New Zealand and Campbell Island, including the type 

 of the species and the types of N. argnta and N. angustata. 



Schneider's Gadus magellanicus was based upon the MS. and drawing of Forster 

 (MS. IV, 46). The latter is a rough sketch but seems to represent an undoubted 

 Notothenia. Since the number of anal rays is given by Schneider as 25, it seems probable 

 that Forster's fish belonged either to this species or to the next, as all other species of 

 Notothenia from the Magellan region have 27 to 35 anal rays. Thompson has expressed 



1 Of 25 specimens from the Patagonian-Falklands region, 1 has 3 spines, 16 have 4, 7 have 5 and 1 has 6.
