 both sexes, have a broad lateral band with reddish 

 blotches, the sea-run specimens being plain silvery. 

 If an angler chances to catch a rainbow in 

 Eastern waters, it will probably be where the 

 Eastern brook trout is also found, and the " red- 

 sides " can easily be distinguished from it by the 

 lateral band, more or less reddish, always on the 

 sides of both sexes, and by the presence of numer-

 somewhat smaller than the spots elsewhere. The 

 brook trout (fontinalis) has red spots; the rain- 

 bows do not have them. In this connection it 

 may also be well to state that if the Eastern an-

 trout, or a Lock Leven, both of which are intro-

 form by its almost square tail, looking as if it was 

 cut in a direct line by a sharp knife ; it may also 

 be recognized by its large scales visible clearly to 

 the eye, and by the big red spots, the largest of 

 which are just above the lateral line in an almost 

 straight row. The Lock Leven trout may be 

 known by its deep red flesh, and by the absence
