52 THE WILSON BULLETIN— March, 1920 



accompanied by seven half-tone reproductions of phott>graphs illus- 

 trative of typical landscape features. The text contains 27 half- 

 tone reproductions of eggs and birds from photographs made in 

 the field. There are ten pages of bibliography, and a full index 

 of the species which are treated. The text is concerned with the 

 occurrence, migration and nesting of the species. The only sug- 

 gestion which the reviewer would offer is that clarity would have 

 been enhanced if mention were made of the distributional area in 

 which each species occurs in addition to giving the political di- 

 vision. In a state of the size and diversified topography of Montana 

 it is not easy for the person who is unacquainted with its counties 

 and cities to trace out the places- in which the species under 

 discussion occurs when only political divisions are mentioned. We 

 have seen no distributional list which is superior to this one, and 

 few its equal.
