River, but were certainly never there before. I think their 

 presence can be accounted for by the action of a squatter on the 

 Upper Minilya River, Mr. M. C. R. Buubury, who wrote a letter 

 to the ' Western Mail' of April 22nd, stating that in the winter of 

 1899 he brought a number of small fish from the Lyons River 

 (which runs into the Gascoyne), and turned them into the 

 Minilya, where they soon spread. The Lyndon River runs west 

 parallel to the Minilya about twenty miles more or less to the 

 north. Both rivers (when they do run) empty into the vast salt- 

 marshes near the coast, but, so far as is known, do not reach the 

 sea. The Cardabia Creek is a tributary of the Lyndon, and 

 during the floods the fish must have come down the Minilya from 

 Mr. Bunbury's house to the marsh, about ninety miles, then 

 swam up to the Lyndon, about thirty miles, and thence up it 

 and its branches. Unless they have the power of living under 

 the dry mud, like the fresh-water Turtles and Frogs, they must 

 all die when the pools dry up, as they are not permanent ; but 

 perhaps the spawn will serve to propagate the species.
