Of the American charr the one most resembling the European species is the Rangeley Lake trout (_Salvelinus oquassa_). The exquisite little fish is known in the United States only from the Rangeley chain of lakes in western Maine. This is very close to the Greenland charr, _Salvelinus stagnalis_, a beautiful species of the far north. 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.

H. ] Still other species of this type are the Sunapee trout, _Salvelinus aureolus_, a beautiful charr almost identical with the European species, found in numerous ponds and lakes of eastern New Hampshire and neighboring parts of Maine. Mr. Garman regards this trout as the offspring of an importation of the ombre chevalier and not as a native species, and in this view he may be correct. _Salvelinus alipes_ of the far north may be the same species. Another remarkable form is the Lac de Marbre trout of Canada, _Salvelinus marstoni_ of Garman. In Arctic regions another species, called _Salvelinus naresi_, is very close to _Salvelinus oquassa_ and may be the same. 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.
