FISHES—REGAN. 37 
A number of South Temperate types extend into this zone, Galaxiidae are 
characteristic, the Nototheniiformes are represented chiefly by Notothenia, and there are 
several peculiar Zoarcidae. 
MaGeELLAN Disrricr. 
This includes Tierra del Fuego, the coasts of Patagonia northward to Chiloe on 
the west and Cape Blanco on the east, and the Falkland Islands. 
BovicHTHYIDAE are represented by the genus Coftoperca (3 spp.), which is 
confined to this district. 
NoroTHENIDAE: Zrematomus, Pleuragramma and the Harpagiferinae except 
Harpayifer bispiis are absent.  Eleginops mactovinus ranges northward to Valparaiso 
and Buenos Aires, and Dissostichus eleginoides southwards to Graham Land.  Peeuliar 
to this area is a natural group of eight species of Notothenia (tessellata group) 
comprising all the species with the upper surface and sides of the head, except the 
snout and praeorbital, scaly, and with the interorbital region rather broad. Two other 
species (LV. cornucola and N. macrocephala) of quite another type occur also in the 
Antipodes District, whilst a third (.V. e/egans), not found elsewhere, may be related 
to NV. cornucola. 
CHAENICHTHYIDAE are represented by a species of Champsocephalus, a genus that 
includes one other species from South Georgia. 
ZOARCIDAE: Llwocoetes (2 spp-)s Phucocoetes (1 sp.), Crossostomus (2 spp.); and 
Platea (1 sp.) are peeuliar ; Ophthalmolycus and Maynea each has a species here and 
another in the Antarctic, whilst Austrolycus comprises two species from this district 
and one from Buenos Aires. 
MuRAENOLEPIDAE. Muraenolepis orangiensis is confined to this district, and 
represents therein the two Antarctic species of the genus. 
GALAxuDAE. Of six species of Galavias in this district three are known to be 
marine; G. maculatus and G. gracillimus have been found in the sea off the Falklands, 
and the former at Puerto Montt also. The range of the species in the sea is not well 
ascertained ; in fresh water they extend at least to Arauco and to the lakes at the head 
of the Rio Negro. 
The majority of the fishes mentioned above are not known to range outside the 
district as delimited ; the remainder of the fishes that oceur within its boundaries are 
Chilean or Argentine forms. 
AntipoprEs Disrricr.* 
This comprises the southern extremity of New Zealand and the islands southward 
to Campbell Island ; whether Macquarie Island should be cluded is unknown. Most 
of the few fishes known are New Zealand species ; Zoarcidae are absent, and the only
