SALMONXM. 



"Body covered with scales, head naked ; barbels 

 none. Margin of the upper jaw formed by the 

 intermaxillaries laterally. Belly rounded. A small 

 adipose fin behind the dorsal. Pyloric appendages 

 generally numerous, rarely absent. Air-bladder 

 large, simple ; pseudobranchise present. The ova 

 falls into the cavity of the abdomen before 

 exclusion. 



" Eresh 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 by a sort of Retro- 

 pinna, found in New Zealand, and, perhaps, a second in New 

 South Wales (KreiFt). 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. 



GALAXID^E. 



" Body naked ; barbels none. Margin of the 

 upper jaw chiefly formed by 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. 



u Fresh waters of the temperate zone of the 

 Southern Hemisphere."
