(2) Corvus corax tibetanus.
THE TIBETAN RAVEN.
Meinertzhagen (Nov. Zool., vol. xxxiii, p. 98, 1826) unites under one name the Tibetan Raven with those from Greenland, Iceland and North-East Asia. I am not satisfied that they are identical, the deep green sheen of the Himalayan and Tibetan race alone sufficing to distinguish it from the more Northern birds.
