Depth of body 4 to 5^ in the length, length of head 3I- to 4^. Snout rather shorter 

 than eye, diameter of which is 3 to 4^ in length of head; interorbital width 2I to 5. 

 Jaws equal anteriorly or lower a little projecting ; maxillary extending to below anterior 

 part or middle of eye (young) or beyond (adult) ; upper surface of head naked, cheeks 

 and opercles scaly; 15 to 20 gill-rakers on lower part of anterior arch. Scales on body 

 rather feebly ctenoid ; 68 to 86 in a longitudinal series from above base of pectoral to 

 caudal; 40 to 52 in upper lateral line, which ends below posterior rays of dorsal; 3 to 

 19 in lower lateral line. Dorsal V-VIII, 32-38. Anal 32-36. Pectoral with 24 or 

 25 rays, | length of head or more, longer than pelvics, which reach the vent in young 

 but not in adult. Caudal truncate (adult) or a little emarginate (young) ; caudal peduncle 

 about as long as deep. Brownish, usually spotted or marbled, or with irregular cross-

The numerous types of this species, ranging in length from 90 to 190 mm., are 

 from Duke of York Island, near Cape Adare, 6 to 10 metres, and from Cape Adare, 

 8 to 16 metres ; those of A'^. hodgsoni, measuring up to 160 mm. in total length, are from 

 the 'Discovery' Winter Quarters, Ross Island. This species seems to occur mainly in 

 shallow water. 



I have examined 7 specimens in the Paris Museum (No. 06 — 119), 70 to 120 mm. 

 in total length, identified by Vaillant as Notothenia cyaneobrancha. Specimens identified 

 by the same author as A^. microlepidota cannot now be found. The British Graham 

 Land Expedition, 1934-7, obtained 4 specimens (60 to 92 mm.), from approximately 

 65° S, 65° W, at a depth of about 12 metres.
