PROTECTION OF FAUNA IN U.S.S.R.—DEMENTIEV 493 
nature and with the fauna of the U.S.S.R. needs international co- 
operation ; for example, the protection of aquatic mammals and migra- 
tory birds. As far as we know, the birds using the great Caspian fly- 
way, protected in the U.S.S.R. by three special refuges—Astrakhan, 
Kyzyl-Agatch, and Hassan-kuli—should definitely be protected along 
the southern coastal areas of the Caspian Sea. The International 
Committee for the Protection of Birds gives a sound means for solv- 
ing this problem. The work of the International Committee for the 
Protection and Hunting of Whales, of which our country has been a 
member since 1946, represents an encouraging example. These are 
only a few examples.
