168 The Wilson Bulletin — No. 61. 



The Birds of the Chicago Area ' strilves us as something new in 

 faunal literature in that political boundaries are wholly ignored by 

 the author. This is as it should be. Political boundaries mean noth- 

 ing unless they chance to coincide with faunal boundaries. The area 

 here treated comprises "all of Cook and DuPage Counties, the nine 

 north townships of Will County and the northern portion of Lake 

 County, Indiana." An interesting feature of the introductory part 

 of this book is a special treatment of "Localities of Interest," with 

 their birds. The body of the book, comprising 170 pages, treats the 

 species systematically, the present accepted name being followed by 

 a list of synonyms, these by the occurrence of the species in the area 

 in question, then often interesting remarks concerning the species, 

 closing with the general range in North America. It is a valuable 

 addition to faunal literature. l. j.
