body. It is a “gregarious and deep-swimming fish, shy of 
taking the bait and feeding largely at night-time. It appears 
to require very pure and mostly deep water for its residence.” 
It is less tenacious of life than the trout. It reaches a weight of 
from one to five pounds, probably rarely exceeding the latter 
in size. The various charr described from Siberia are far too 
little known to be enumerated here. 
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. 
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 marstont of Garman.
