ANTARCTIC ZONE 99 



Harpagiferidae. Artedidraco (5 species); Dolloidraco (i species); Histiodraco 

 (i species); Pogonophryne (2 species); Harpagifer (i species). 



With the sole exception of Harpagifer bispinis, which occurs also in the Kerguelen- 

 Macquarie District, as well as in the Patagonian Region of the Subantarctic Zone, all 

 the genera and species of this family are peculiar to the Glacial District. 



Bathydraconidae. Bathydraco (5 species); Gerlachea (i species); Racovitzia (2 

 species); Prionodraco (i species); Cygnodraco (i species); Parachaenkhthys (2 species); 

 Psilodraco (i species); Gymnodraco (i species). 



All the members of this family are confined to the Glacial District. According to 

 Regan {t.c, p. 33), Bathydraco must be regarded as oceanic, but, in spite of their being 

 taken mainly in deep water, it seems likely that the related genera Gerlachea, Racovitzia, 

 and perhaps Prionodraco, should be reckoned as coast fishes. None of the specimens of 

 Bathvdraco, however, has been captured far from the coast of the Antarctic Continent. 

 Cygnodraco, Parachaenichthys, Psilodraco and Gymnodraco are clearly to be looked upon 

 as coast fishes. 



Chaenichthyidae. Champsocephalus (i species); Pagetopsis (i species); Pseudo- 

 chaenichthys (i species); Dacodraco (i species); Chaenocephalus (i species); Cryodraco 

 (2 species); Chionodraco (2 species); Chaenodraco (i species). 



The members of this family are highly characteristic of the Glacial District, only 

 three species being found outside the area. Of these, the two species of Chaenichthys 

 are confined to Kerguelen, and the second species of Champsocephalus, C. esox, occurs 

 in the Patagonian Region of the Subantarctic Zone. 



Zoarcidae. Lycenchelys (i species); Lycodichthys (i species); Austrolycichthys 

 (3 species); Melanostigma (i species). 



The species of Maynea from South Georgia mentioned by Regan {t.c, p. 34) must 

 be removed from the list of Southern Zoarcidae (see footnote on p. 81). The species of 

 Melanostigma is found also in the Subantarctic Zone. The four species of Zoarcidae 

 from the Antarctic Continent belong to two peculiar genera, Lycodichthys and Austro- 

 lycichthys, related to the Patagonian genera Iluocoetes and Austrolycus respectively. 



Muraenolepidae. This family includes a single genus, of which four species have 

 now been described, one from the Patagonian Region, one from Kerguelen, and two 

 from the Glacial District. One of these last (M. microps) has also been recorded from 

 the neighbourhood of the Burdwood Bank, just north of the Antarctic Convergence, 

 and, thus, outside the Antarctic Zone. 



The additional collections obtained since the publication of Regan's report (1914^) 

 have increased the number of species known to have a circumpolar distribution, but 

 our knowledge of the range of many species in the Glacial District is still far too 

 incomplete to make possible any subdivision of this area. Of the 6 species of Notothenia 

 occurring on the coasts of Antarctica, only one (A^. coriiceps) has a circumpolar dis- 

 tribution, whereas, of the 12 species of Trematomus, 7 have been recorded from both 

 the Weddell and Victoria Quadrants. Pleuragramma antarcticum and Dissostichus 

 mawsoni are likewise known to be circumpolar. Of the Harpagiferidae, 3 out of
