Hak. Its area of distribution begins in the moun- 
tains of Irkutsck and Kiathtka in Siberia, thence it 
passes on to the territory situated to the north of lake 
Baikal in the neighbourhood of the Ussuri. It is 
found very frequently in all the Alpine regions which 
are watered by the Amour. It is probable that it 
descends to the Alps of N. China. On the American 
Continent it is found in Alaska and California.
