well developed, knob-like, and almost as prominent as in Quiscalus.

ORNITHOLOGY. — The migration of North American birds. IX. 

 Crows. Harry C. Oberholser. Bird Lore 21: 100-102. 1919. 

 The weU-known Corvus brachyrhynchos, as represented by five sub- 

 species, including Corvus brachyrhynchos caurinus, occupies the greater 

 part of the United States and Canada. It is resident except in the 

 northern part of its range, for which region the dates of its spring and 

 autumn migration are here given. The distribution of Corvus ossi- 

 fragus, the European Corvus frugilegiis, and the European Corvus cor- 

 nix, are also added as of interest in this connection.
