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
