OF THE KERGUELEN REGION OF THE GREAT SOUTHERN OCEAN.

indicate that many of the deep-sea species have a wide distribution. The probability 

 is that further trawlings and dredgings will yield a very large number of new species 

 and genera.

The preceding list of species from the deep-water area of the Kerguelen Region 

 (List I.) shows that in the region of the Southern Indian Ocean represented by the eight 

 Stations referred to, the Challenger procured in depths exceeding 1260 fathoms representa- 

 tives of 272 species and varieties of Metazoa, belonging to 186 genera. The large propor- 

 tion of genera relatively to the number of species is striking, being as 1 to 1*46. 



An examination of the list shows that 9 of the species have received no specific 

 names, owing to the specimens being in an unsatisfactory condition or to other causes, and 

 they cannot therefore be taken into account in any discussion of distribution. There are 

 besides 6 varieties enumerated, as well as the species to which they belong, but in what 

 follows the distribution of each species is considered as a whole, including varieties. Of 

 2 species (Stephanoscyphus simplex and Bairdia bosquetiana) we have no trustworthy 

 information as to distribution, so that we must deduct from the total number of species 



1 Wyville Thomson says this species was taken at, at least, six or seven Stations in the Atlantic and Southern Sea, 

 but it is recorded in the Challenger Report only from two of these Stations.
