THE FISHES OF THE SWEDISH SOUTH POLAR EXPEDITION. 
37 
The specimens of this interesting “pickerel-shaped” fish measured about 45 cm. 
without caudal. The colour was brown above, somewhat lighter below, with nurpe- 
rous roundish blackish dots on the back and the sides. 
10. Champsocephalus gunnari 1 n. sp. 
7 specimens from stat. 22, Cumberland Bay, South Georgia, depth 75 m., clay 
and algae, temperature at the bottom + i, 5 ° C. 14th of May 1902. 
2 specimens from stat. 32, South Fjord, Cumberland Bay, South Georgia, depth 
195 m., clay mixed with stones, temperature at the bottom + i, 45 ° C. 29th of 
May 1902. 
Similar to Ch. esox (GÜNTHER) in its general shape, but differing from the same 
in many points, with regard to number of fin-rays, relative dimensions etc., and as 
these differences are constant it appears to be the most correct proceeding to establish 
a new species for the Champsocephalus from South Georgia. The relative dimen- 
sions of the same and the discrepancies from Ch. esox shown by them become quite 
conspicuous from the table of measurements appended. For the identification of the 
fish from South Georgia even without the aid of careful measurements the following 
diagnose may be sufficient. 
D. 9 (10 2 ) I (37 2 ) 38—40; A. 36—38. 
Snout and upper jaw shorter than in Ch. esox so that the posterior end of the 
maxillary hardly reaches the vertical through the anterior margin of the pupil and 
never beyond the same (in Ch. esox to the middle of the pupil). Eye larger than 
in Ch. esox, only about 5 (or 5 1 /*) times in length of head, measured without the 
opercular flap beyond the spine (in Ch. esox 6 2 / 3 — 772). Interorbital width without 
supraorbital skin greater about y/ 2 — 3 2 / 3 times in length of head (in Ch. esox 
4V2 — 5 times). The profile contour continues to rise considerably behind the eye, 
so that the height just in front of first dorsal equals the length of the snout and 
half the diameter of the eye, while the height at the same place in Ch. esox is a 
.good deal shorter than the snout alone. Greatest thickness of head in the preoper- 
cular or opercular region decidedly greater than length of snout (in Ch. esox much 
shorter than snout). The opercle has at its posterior border two spines, the upper 
one of which is always divided at least in two but sometimes in three points. Pec- 
toral very long, normally reaching to fifth or sixth anal ray and even in females 
with the belly distended by ripe ovaries reaching the second or third anal ray (in 
Ch. esox never reaching anal). Height of first dorsal variable, but its longest rays 
1 I take the liberty of naming this fish after Dr. J. Gunnar Andersson who was the chief of the 
expedition during its cruise to South Georgia.
