scales. Dorsal IV-VI, 36-40. Anal 34-36. Pectoral with 22 or 23 rays, f to | length of 

 head, generally rather shorter than pelvics, which reach vent or anal. Caudal rounded 

 or subtruncate ; caudal peduncle much deeper than long. Body with 2 or 3 series of 

 large, partly confluent, irregular blackish spots and blotches, sometimes forming more 

 or less definite oblique cross-bars ; cheek usually with two oblique dark stripes ; a round 

 black spot on spinous dorsal; soft dorsal, caudal and anal with or without series of

Hab. Graham Land and neighbouring islands; South Shetlands; South Orkneys; 

 South Sandwich Islands ; South Georgia. 



This species was originally described from 7 specimens from Cape Seymour and 

 south of Snow Hill, Graham Land, and from numerous specimens from South Georgia, 

 at depths ranging from 12 to 250 metres. It is very common at South Georgia, at all 

 depths from 10 to 250 metres. In life the fish appears to be reddish or reddish-brown 

 on the back and sides and silvery white below ; the spots are dark brown. 



In general appearance this species is very similar to A'^. mizops, from Kerguelen, but 

 may be readily distinguished by the naked occiput and interorbital region, the some- 

 what more numerous dorsal and anal rays, and the smaller scales. 



I have examined 3 specimens in the Paris Museum, 62 to 118 mm. in total length, 

 from the South Shetlands.
