 length of head. Maxillary extending to below anterior J or ^ of eye ; upper and middle 

 opercular spines only free distally, appearing as a single bifid (sometimes trifid) spine.

Fig. 43. Champsocephalus gunnari. x J. 



Hah. South Georgia; Kerguelen. 



This species was originally described from 9 specimens, 322 to 436 mm. in total 

 length, all from Cumberland Bay, South Georgia, 75 to 195 metres. C. gunnari may 

 be readily distinguished from the Patagonian C. esox by the deeper body, rather shorter 

 head, larger eye, shorter maxillary, form of the opercular spines ; and higher number of 

 dorsal and anal rays, as well as by the difference in coloration. Recently, the B.A.N.Z. 

 Antarctic Research Expedition obtained 2 examples (235 and 300 mm.) of this species 

 from Kerguelen at a depth of 91 metres, as well as remains of other specimens from the 

 stomachs of fishes and penguins.

Body naked, moderately elongate; two lateral lines, without bony plates. An antrorse 

 curved rostral spine; eye behind middle of length of head. Teeth in jaws small, sharp,
