regions, both for their numbers and their value to the human 
race, are here few in number and unimportant, being limited 
to a few species of “otella, Physiculus, and Pseudophysis. 
The Opnipipm are far from numerous, but are sufficiently 
interesting. A species of Dinemolichthys comes from the 
extreme North. A Genypterus (two feet long) is found in 
Hobson’s Bay. Typhlonus and Aphyonus are genera found at 
ereat depths (“Challenger”) on the North- east Coast, and 
Fierasper and Congrogadus come from the coral reefs of the 
North. The Macruripv@ of Australia consists of one species 
of Macrurus and three of Coryphenoides, all from the South 
Coast, one at a depth of 2000 fathoms (“Challenger.’’) 
The PLevronncrrym of Australia number about 40 species. 
They are probably much more numerous, as the use of the 
trawl net, the only means of catching them, has never been 
introduced into the country. The well-known genera and 
species of this family in the European seas are represented i in 
Australia by different genera for the most part, but there is 
nothing conspicuously “distinctive. The Stnuripm are not 
numerous. Several genera are found in the fresh waters of 
the northern portion of Australia, and a fine species of Copido- 
glanis is abundant in most of the inland rivers. The genus 
© widoglunis is abundant on the Hast Coast. Species of Avius 
are found among the coral reets. 
The ScopELIDm are deep sea fishes, and probably widely 
distributed. The genera chiefly represented in Australia are 
Saurus and Saurida. The beautiful Aalopus (Sergeant 
Baker) is not uncommon. Scopelus and Alawpidosaurus are 
also found occasionally. Of the SromraTipm two species 
have been fourd at depths of over 2000 fathoms, one on the 
North-west, the others on the South Coast (“ Challenger.’ ’) 
The oveat family of SALMONID# is entirely unknown in 
Australia, with the exception of two very curious genera, each 
of one species, found in the rivers of the colder 1 regions of the 
south. These are the genera Prototoctres, a small fish found 
in the Vi tepoue and Tasmanian rivers, and Retropinna, also 
found in New Zealand rivers. The GAaLaxrpa constitute a 
family remarkable in many respects. They are found only in 
the rivers of the extreme south of South America, of the 
Falkland Islands, of the South of New Zealand, of Tasmania, 
of Victoria, and the rivers of New South Wales flowing from 
the great mountain range of the country. The peculiar distri- 
bution of these very peculiar fishes gives support to the belief 
held by many scientific men that a ereat Antarctic Continent 
at one time extended from America to Australia. About 20 
species of the one genus G'alaxias have been described trom 
Australia. 
All tne genera of the Scomprescopim are found in
