This paper contains a most interesting theory in explanation of the 
fact that the squirrel, beaver, bear, lynx, and several other strictly Euro- 
pean animals, are entirely absent from the Crimean forests, although 
present in those of Southern Russia, which are separated from the 
Crimea by a considerable space of steppe-land ; while the roebuck and 
red deer are found there as well as in the Caucasus. The author’s general 
conclusions are (1) that the South Russian steppes have never been covered 
with forests ; (2) that the Mammals of Ihe Crimea have entered it, over 
the frozen Kertch Straits, from the Caucasus range, and not from the 
Russian mainland ; (3) that the Caucasus has received its Mammals, not 
from European Russia, but from Siberia or Persia, by way of Asia 
Minor ; and (4) that the two streams of animal life from the north and 
south, on the isthmus between the Black and Caspian Seas, have never 
met, the South Russian steppes having proved an absolute barrier to all 
forest forms.
