Lac de Marbre Trout ; Marston Trout 



to take the fly readily, and must be classed among the most 

 beautiful and active of American game-fishes. 



It is regarded by Professor Garman as allied to the Oquassa 

 trout, from which it differs in the longer maxillary, stronger den- 

 tition, deeply notched caudal fin, larger size and different colouration. 

 It seems even more closely related to specimens which have been 

 identified by Dr. Bean with Salvelinus rossi of Richardson, which 

 may be identical with the Greenland charr. 



Little or nothing has been recorded regarding its game qualities, 

 but its trim appearance and rich colouration, together with the cold 

 water in which it lives, would indicate a fish well worthy the 

 attention of anglers.
