LIPARIDAE 87 



This species, which was not previously represented in the British Museum col- 

 lection, was originally described from 2 specimens, 63 and 105 mm. in total length, 

 from South Fjord, Cumberland Bay, depth 

 195 metres. 



Liparis steineni, described by Fischer (1885, 

 Jahrb. Hamb. Wiss. Anst., 11, p. 63) may 

 belong to this genus. The types, 2 specimens ^'S- 57- Careproctus georgiams. xf. 



65 and 70 mm. in total length, were said to be from tide pools or shallow waters, 

 Royal Bay, South Georgia.

 Hab. South Atlantic, north of the Falkland Islands ; north-east of South Georgia ; 

 southern Indian Ocean, near Prince Edward's Island. 



The type of the species, 134 mm. in total length, was collected by the ' Challenger' 

 at Station 145, at a depth of 580 metres. The 'William Scoresby' obtained another 

 example, 238 mm. long, from 45° 45' 00" S, 59° 35' 00" W, at a depth of 311 to 247 

 metres. This represents another species found in both the Antarctic and Subantarctic 

 Zones. 



GENERAL PART 

 THE ANTARCTIC ZONE 



In his report on the fishes of the 'Terra Nova' Expedition, Regan (19146) has dis- 

 cussed in detail the distribution of Antarctic and Subantarctic fishes, and has defined 

 three zones of distribution south of the Tropical Zone, namely, the South Temperate 

 Zone, the Subantarctic Zone, and the Antarctic Zone. This last region was said to 

 include "the coasts of the Antarctic continent and the islands that lie to the south of 

 the isotherm of 6° C, with the possible exception of Macquarie Island". This zone 

 was further subdivided into two districts. Glacial and Kerguelen. The Glacial District 

 includes the coasts of the Antarctic continent and neighbouring islands, together with 

 South Georgia, the South Sandwich Islands, and Bouvet Island, all situated within the 

 extreme limit of the pack-ice. The Kerguelen District includes the island of Kerguelen 

 and also Heard Island, the Crozet Islands, and Marion and Prince Edward Islands : as 

 will be seen, there appears to be good reason for including Macquarie Island within 

 this district. 



The mean annual surface isotherms of 6° C. and 12° C. correspond on the whole 

 fairly closely to the Antarctic and Subtropical Convergences as delimited by Deacon^ 

 in his valuable paper on the hydrology of the Southern Ocean. The following classifi-
