1 The study of the Antarctic surface fish-fauna, and its comparison with that of the Arctic regions, is one of the 

 most instructive portions of zoogeography. The abundance of fish-life appears to decrease in the same proportion to- 

 wards both Poles. The forms peculiar to the Antarctic are analogous to those of the north ; thus the Cottoids of the 

 north are represented by tbe Notothenias, Chcenichthys, &c, of the south, the Salmonoids by the Haplochitonidas ; yet 

 there is no such relation between the representative forms as might be considered to be genetic. The resemblance is 

 rather an external one, indicated by the general form of the body, structure and development of the fins, presence of 

 an adipose fin, &c. Besides those fishes which are peculiar to the Antarctic some other forms well developed in the 

 north, but nearly or entirely disappearing between the tropics, reappear, as Sehastes, Agonus, Spinax, Myxine, differing 

 but little from their northern congeners. — (Gunther, Zool. Chall. Exp., part 6, p. 14.) 



2 It may be of interest to insert here some general remarks of Dr von Willemoes-Suhm on the results of the 

 shallow-water dredgings and trawlings taken at Kerguelen by the Challenger in the month of January 1874, extracted 

 irom the Challenger Report, Summary of Results, pp. 478-480, as he refers to a few animals not included in our
