(The species of this group are in general smaller, finer, hand- 
somer, and more wary than the Salmon, and they inhabit in general 
colder waters. Besides the native species, attempts have been 
made to introduce the following: Salvelinus alpinus L., the Euro- 
pean charr, Silbling, or Ombre Chevalier, a species very close to 
S. oquassa and S. malma (Walbaum), the “Dolly Varden Trout,” 
or “Bull Trout” of the Rocky Mountain slope; very close to 8.

usual teeth around edge of tongue); head of the vomer with a raised 
crest, which projects backward, free from and parallel with the shaft;
