 gill-rakers on lower part of anterior arch. Dorsal V-VI, 34-37. Anal 31-33. 

 Pectoral f to |- the length of head, longer than pelvics, which rarely reach the vent. 

 Caudal rounded or subtruncate. Caudal peduncle as long as deep, or deeper than long. 

 78 to 96 scales in a longitudinal series from above base of pectoral fin to caudal ; lateral 

 lines vestigial, without or with only a few tubules. Yellowish, with dark spots or 

 irregular cross-bars ; dorsal and caudal sometimes with series of spots. 



Graham Land and neighbouring islands ; Wilhelm Land ; Victoria Land. 



Here described from several specimens, 180 to 270 mm. in total length, including 

 the types of the species, from Cape Adare and Duke of York Island, near Cape Adare 

 (Southern Gross), and examples from the Discovery winter quarters, Ross Island. A 

 specimen of 80 mm. was obtained in March 1903 by the Scotia, at Station 325, in 

 Scotia Bay, South Orkneys; depth 10 to 15 fathoms.
