Family TETRAONID A. 
The Grouse (the trivial name for the members of this family) are 
among the most important of edible birds. They exist in very cir- 
cumscribed limits, namely the northern portions of the Old and New 
Worlds. Those which frequent Britain are the magnificent Ca- 
pereailzie, the Blackcock, the Red Grouse, and the Ptarmigan. 
Neither the Capercailzie nor the Blackcock is found in America ; 
but that country is inhabited by species equally fine which are not 
found elsewhere.
