 pletely scaled; 16 gill-rakers on lower part of anterior arch. Dorsal 36. Anal 31. 

 Caudal subtruncate. Pectoral truncated, as long as head without snout, reaching origin 

 of anal. About 140 scales in a lateral longitudinal series, about 60 in the lateral line, 

 which is complete. Brownish ; fins dusky.

 Bouleng., Nat. Aniardic Exped. Nat. Hist., ii., Fish., p. 4, pi. i. fig. 3 (1907). 



Depth of body 9 in the length, length of head 3. Snout If as long as diameter of 

 eye, which is 4^ in the length of head, interorbital width 14. Lower jaw projecting; 

 maxillary reaching vertical from anterior margin of eye ; cheeks naked below the sub- 

 orbitals ; 11 gill-rakers on lower part of anterior arch. Dorsal 34. Anal 29. Caudal 

 subtruncate. Pectoral as long as head behind middle of eye, reaching origin of anal. 

 About 90 scales in a lateral longitudinal series, about 55 in the lateral line, which is 

 complete. Brownish ; fins dusky. 



South-west of Balleny Islands, 252 fathoms. 



Here described from the type, 210 mm. in total length. In the original description 

 the number of gill-rakers was erroneously given as 6, and of dorsal rays as 39 ; the

Depth of body 9 to 10 in the length, length of head 3|^. Snout If as long as eye, 

 the diameter of which is 5 in the length of head, interorbital width 12 or 13. Lower 

 jaw projecting ; maxillary not reaching the vertical from anterior margin of eye ; cheek 

 naked below the suborbitals; 19 to 22 gill-rakers on lower part of anterior arch. 

 Dorsal 38. Anal 31. Caudal subtruncate. Pectoral as long as head without snout, 

 extending a little beyond origin of anal. About 100 scales in a lateral longitudinal 

 series, 36 to 40 in the lateral line, which ends at a distance from the caudal equal to 

 \ its own length. 



Two specimens, 133 and 145 mm. in total length, taken by the Scotia at Station 417,
