now the lobo will accompany strings of mules as 
soon as it becomes dusky. They are seen bounding 
from bush to bush by the side of travellers, and 
keeping parallel with them as they proceed, waiting 
an opportunity to select a victim; and often suc- 
ceeding, unless the muleteers can reach some place 
of safety before dark, and have no dangerous passes 
to traverse. Black wolves occur again in the moun- 
tains of Friuli and about Cattaro. 
The Vekvoturian mountain-wolf of Russia is ano- 
ther race of the black species. From the females, 
crossed by domestic dogs, a hybrid progeny has 
been obtained at Moscow, which, according to Pal- 
las, resembled wolves, but carried the tail higher 
and had a hoarse barking. ‘“ They multiply,” says 
that celebrated naturalist, “‘ among themselves, and 
some of the whelps are greyish, rusty, and even 
white, like the wolves of the arctic circle. One of 
those I saw, in shape, tail, fur, and voice, was so 
hke a cur, that, was it not for his head and ears, his 
ill-natured look and fearfulness at the approach of 
man, I should have hardly believed that it was of 
the same breed.” * 
The Rossomak of the Lenas, in Siberia, is another 
canine of a shining black colour, probably of the 
same species as the former, but with a more valu- 
able fur. 
The Derboun of the mountains of Arabia and the 
south of Syria is the last black canine we can refer 
to the wolf. Little is known concerning this ani-
