THE SALMON FAMILY. 77 



(Salvelinus stagnalis). The exquisite little fish is 

 known in the United States only from the Rangeley 

 chain of lakes in western Maine. Quite lately 

 specimens of what appears to be the same species 

 have been taken in Arctic America, about Cum- 

 berland Gulf. Still later, Dr. T. H. Bean has shown 

 its identity with the Greenland charr. Whether 

 the species still inhabits any intervening waters is 

 unknown. The Rangeley trout is much slenderer 

 than the common brook-trout, with much smaller 

 head and smaller mouth. In life it is dark blue 

 above, and the deep red spots are confined to the 

 sides of the body. The species rarely exceeds the 

 length of a foot in the Rangeley Lakes, but in some 

 other waters it reaches a much larger size. So far 

 as is known it keeps itself in the depths of the lake 

 until its spawning season approaches, in October, 

 when it ascends the stream to spawn. 



Another beautiful little charr, allied to Salvelinus 

 stagnalis, is the Floeberg Charr (Salvelinus arcturus). 

 This species has been brought from Victoria Lake 

 and Floeberg Beach, in the extreme northern part 

 of Arctic America, the northernmost point whence 

 any salmonoid has been obtained. 



The American Charr, or, as it is usually called, 

 the Brook Trout (Salvelinus fontinalis), although 

 one of the most beautiful of fishes, is perhaps the 

 least graceful of all the genuine charrs. It is tech- 

 nically distinguished by the somewhat heavy head 

 and large mouth, the maxillary bone reaching more 

 or less beyond the eye. There are no teeth on the 

 hyoid bone, traces at least of such teeth being 

 found in nearly all other species. Its color is
