i io Salmonida? 



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. 



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
