' Tlio study of tliL- Antarctic surface tish-fauna, and its comparison with that oi llio Arctic I'c^yions, is one of the 

 most instructive portions of zoogcof^raphy. Tlie al)undance of fish-life appears to decrease in tlie 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 the Notothcnur, Chtcnichthiis, &c., of the south, the Salmonoids by the Ha]ilochitouida! ; yet 

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

 rather an external one, indicated by the general form of the body, structure and dcvclopmeut of the tins, presence of 

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

 north, but nearly or entirely disappearing between the tropics, reappeai', as Stbantex, Aijomi-i, SpiiKix, Mii.dm; differing 

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



- 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 trawliiigs taken at Keiguelen by the Challenger in the month of January 1874, extracted 

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