FISHES REGAN. 37 



A number of South Temperate types extend into this zone, Galaxiidae are 

 characteristic, the Nototheniiformes are represented elderly by Notothenia, and there are 

 several peeuliar Zoarcidae. 



Magellan District. 



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 Cottoperc.a {'■■> spp. ). which is 

 confined to this district. 



Nototheniidae : Trematomus, Pleuragramma and the Harpagiferinae except 

 Ilarpaqifer Inspirits are absent. Eleginops maclovinns ranges northward to Valparaiso 

 and Buenos Aires, and Dissostichus eleginoides southwards to Graham Land. Peculiar 

 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 (A. cornucola and N. macrocephala) of quite another type occur also in the 

 Antipodes District, whilst a third [N. elegans), not found elsewhere, may be related 

 to N. cornucola. 



CHAENICHTHYIDAE are represented by a species of Champsocephalus, a genus that 

 includes one other species from South Georgia. 



Zoarcidae : Tluocoetes (•! spp.), Phucocoetes (1 sp.), Crossostomus (2 spp.), and 

 Platea (l sp.) are peculiar; Ophthalmolycus and Maynea each has a species here and 

 another in the Antarctic, whilst Amtrolycns comprises two species from this district 

 and one from Buenos Aires. 



.Mckaenolepidae. Muraenolepis orangiensis is confined to this district, and 

 represents therein the two Antarctic species of the genus. 



Galaxiidae. Of six species of Galaxias in this district three are known to be 

 marine : G. macalatus 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 occur within its boundaries are 

 Chilean or Argentine forms. 



Antipodes District.* 



This comprises the southern extremity of New Zealand and the islands southward 

 to Campbell Island ; whether Macquarie Island should be included is unknown. Most 

 of the few fishes known are New Zealand species ; Zoarcidae are absent, and the only
