 of the scales, as before stated, being the basis of 

 the Doctor's conclusions. Certainly it is less 

 slender than the cut-throat, and the snout is more

 jaw, and no teeth at the base of the tongue ; 

 again, it seldom grows larger than a pound in

 fish " apparently merges into the ordinary rainbow 

 southward, if indeed the two forms are dis- 

 tinguishable. We know of no diagnostic char- 

 acter, but further comparison is needed." 



This fish is the one sought after by the 

 enthusiastic anglers of Seattle and Tacoma, and

The " McCloud River rainbow trout " {Salmo 

 irideus sJiasfa, the subspecific from Mt. Shasta, 

 California) is of peculiar interest, as it was with
