110 Salmonidz 
In Arctic regions another species, called Salvelinus narest, is 
very close to Salvelinus oquassa and may be the same. 
Another beautiful little charr, allied to Salvelinus stagnalts, 
is the Floeberg charr (Salvelinus arcturus). This species has 
been brought from Victoria Lake and Floeberg Beach, in the 
Fic. 74.—Speckled Trout (male), Salvelinus jontinalis (Mitchill). New York. 
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 technically 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 somewhat different from that of the others, the red spots 
being large and the black more or less mottled and barred with 
darker olive. The dorsal and caudal fins are likewise barred 
or mottled, while in the other species they are generally uniform 
in color. The brook-trout is found only in streams east of the 
Mississippi and Saskatchewan. It occurs in all suitable streams 
of the Alleghany region and the Great Lake system, from the 
Chattahoochee River in northern Georgia northward at least 
to Labrador and Hudson Bay, the northern limits of its range 
being as yet not well ascertained. It varies greatly in size, 
according to its surroundings, those found in lakes being 
larger than those resident in small brooks. Those found
