GUIDE TO THE 
as well as on the long one, along the passage through 
which we came and through which we will now 
return, we see the 
Game Birds 
displayed. The collection of Tetraonidae is probably 
the finest in the world, especially with regard to 
hybrids and varieties, which are very frequent in this 
group of birds, on account of their polygamous habits. 
The sportsman will be delighted to view this magni- 
ficent series, but by far the larger number is kept in 
skins in the rooms containing material for study. The 
rarest of the hybrids are supposed to be the hybrid 
between the Blackcock and Hazel-Grouse, and the 
hybrids of Pheasant and Capercaillie, Pheasant and

Most of the greatest rarities and finest specimens are 
from Eussia and Siberia, others from Scotland. The 
Eackelhahn,” or the male offspring of the pairing 
of Blackgame and Capercaillie, is the least rare of all 
these hybrids. The British representative of the 
Willow-Grouse {Lagopus albus) is the Red Grouse 
{Lagopus scoticus)^ the celebrated Scotch game bird
