and finest, yet it has rarely been transplanted to waters 

 other than those to which it is native. 



The true cut-throat is found in the coastwise streams 

 from Kadiak to Eel River, and its greatest abundance is in 

 the Columbia. It is also unchanged in the upper waters 

 of the Missouri, for there is a clean runway from the Snake 

 River in Idaho, through Pacific Creek and Atlantic Creek 

 in Two Ocean Pass above Yellowstone River and the Upper 

 Missouri. It has one variant in the State of Washington, 

 the Waha Lake trout, SaJnio boiivieri. In this mountain 

 lake without outlet, Bender and Bouvier found this peculiar 

 form, with spots on its posterior parts only, and the head 

 shorter than in the true cut-throat. Near to the true cut- 

 throat is the trout of Utah Lake, and the Great Basin of 

 Utah, Salmo virginalis. This form is profusely speckled, 

 the spots small and mainly on the back, just as numerous 

 anteriorly as on the tail. The scales are rather larger than 

 in the true cut-throat. 



In the Platte and Arkansas Basins is the green-back trout, 

 Salmo stomias, a bright-colored form, with large black spots 

 mainly gathered on the tail, and with small scales. It is one 

 of the smaller kinds of trout, but abundant and game. 



In the Twin Lakes near Leadville, the large and handsome 

 yellowfin trout, Salmo macdonaldi, is found, in company 

 with the other. This species has small scales, small black 

 spots, mostly on the posterior region, and the sides and 

 lower fins are bright lemon-yellow. The only specimens of 

 this trout known were taken in the summer of 1888 by 

 George R. Fisher and Dr. Jordan. Mr. Fisher, one of the 

 most skilful of anglers, insisted on the existence of the 

 species and on the fact that he could catch it. He took the 

 present writer on a long row, before breakfast, in the very 

 early morning, and all the fish that were caught rose to 

 his fly from the deep water of the lower lake. The largest 

 of these weighed nine pounds and was perhaps the most 

 beautiful of all the trout. The species was described in
