 a good fighter. It is of a v,ery savage nature, and its jaws 

 are well-armed with sharp teeth.

 New Zealand. Though they are small, some of them being 

 even tiny, many of them are very prettily-marked and 

 spotted, and this, coupled with their activity in the water

and their habit of swimming and leaping at the surface, has 

 given rise to the name of Mountain Trout, which is so often

 offshoot of the Salmon-family, in the process of adaptation,
