the fleshy portion of the tail and the base of each of 

 the fins more muscular : the males are the strongest in 

 the water, but the females are the most eager for bait, 

 and their teeth are rather smaller. The colours of the 

 males in the spawning season are the head olive brown, 

 the body reddish brown or orange brown, that of the females 

 a blackish grey ; the dorsal fin reddish brown, spotted with 

 darker brown ; the tail dark brown ; the other fins dusky 

 brown. The general colour at other times like that of the 

 Salmon-Trout. 



The Salmo hucho of English authors is probably the 

 same as the Bull-Trout .
