 3 to 3^ in the length of head, interorbital width 8 to 9. Maxillary extending to below 

 anterior j or 5 of eye ; upper surface of head naked ; cheeks and opercles scaly ; 

 11 or 12 gill-rakers on lower part of anterior arch. Dorsal IV, 37. Anal 32-33. 

 Pectoral f to f length of head, somewhat longer than pelvics, which reach vent or origin 

 of anal. Caudal rounded. Caudal peduncle nearly as long as deep. 58 to 62 scales 

 in a longitudinal series from above base of pectoral fin to caudal, 39 to 43 in upper

 Victoria Land. 



Here described from the types, three specimens 150 to 250 mm. in total length, 

 from Cape Adare, 5 to 8 fathoms, and Duke of York Island, near Cape Adare, 4 fathoms. 



The pectoral arch of this species is exactly similar to that of the closely related 

 T. newnesii, as figured on p. 331. 



(3) Trematomus borchgrevinkii. 



Bouleug., "Southern Cross" Pisces, p. 179, pi. xii. (1902); Pappeiiheim, Deutsche Sildpolar-

Depth of body 4 to 5 in the length, length of head 3 J to 4J. Diameter of eye 4 to 5 in 

 length of head, interorbital width 3 to 4. Maxillary extending to below anterior ^ of 

 eye; upper surface of head naked ; upper parts of cheeks and opercles scaly ; 16 to 19 

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

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

 Caudal rounded or subtruucate. 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 Cross), and examples from the Discovert/ 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.
