SALMONIDiE. 
“Body covered with scales, head naked ; harhels 
none. Margin of the upper jaw formed hy the 
intermaxillaries laterally. Belly rounded. A small 
adipose fin behind the dorsal. Pyloric appendages 
generally numerous, rarely absent. Air-bladder 
large, simple ; pseudohranchise present. The ova 
falls into the cavity of the abdomen before 
exclusion. 
“ Presh waters of the temperate and Arctic re- 
gions of the Northern Hemisphere ; many species 
periodically descending to the sea. One genus 
from New Zealand; two genera pelagic.” 
Only represented in the Australian seas hy a sort of Hetro- 
pinna, found in New Zealand, and, perhaps, a second in New 
South Wales (Krefft). This almost total absence of a family 
whose sorts abound in the fresh waters of South America, forms 
one of the most curious features of Australian ichthyology. 
GALAXIDiE. 
“Body naked; harhels none. Margin of the 
upper jaw chiefly formed hy the intermaxillaries, 
which are short and continued by a thick lip, behind 
which are the maxillaries. Belly rounded. Adipose 
fin none; dorsal opposite to anal. Pyloric appen- 
dages in small number. Air-bladder large, simple . 
pseudobranchiee none. The ova fall into the cavity 
of the abdomen before exclusion. 
“ Fresh waters of the temperate zone of the 
Southern Hemisphere.”
