mines being allowed to find its way to tlie lake. That its introduction to 

 the Tarra has not been an unmixed blessing is clear from the following 

 remarks of Prof. McCoy: — " The Cod is now established in the Tarra, but

 several of the native fishes of that river, particularly the Blackfish ( Gadopsis 

 marmoratus) and the Tarra Herring or Australian Grayling {Prototroctes 

 marcena), which have now disappeared from the lower parts of the Tarra 

 altogether." 



This magnificent species attains to a length of nearly five feet, and a 

 weight of upwards of one hundred pounds.
