TJie Birds of El Paso (Jounty, Coloritdo. I and II. By Chailos K. H. 

 Aiken aud Edward E. Warren. Colorado College Publications, Gen- 

 eral Series Nos. 74, 75, 76. May, Jnne-Septeniber, 1914. 

 The life zones included in this county are Upper Sonoran, Transition, 

 Canadian, Hudsonian, and Ai'ctic-Alpine. Lists of the birds which are 

 peculiar to these several zones are given. A history of the work <lone in 

 the county is given, the climate is described, and the altitudes given. 

 The birds are divided according to occurrence as resident throughout the 

 year, 46 species; summer residents, 84 species; breeding birds which 

 occasionally winter, 7 species; non-breeding birds which winter, 28 

 species; non-breeding birds which pass through in migration, 52 species; 

 non-breeding birds of occasional occurrence, 51 species; exterminated 

 species, 3; introduced species, 4, making a grand total of 275 species. 

 There are many good halftone pictures from photograjihs, and in the 

 treatment of the species in the body of the paper the annotations are 

 interesting and valuable. This ]iaper is a distinct contri])ution to local 

 ornithology. L. .J. 



The Birds of Waukesha County, Wisconsin. By Alvin R. Cahn. Bul- 

 letin of the Wisconsin Natural History Society, Vol. XI ( Xew 

 Series), No. 4, December, 1913. Pages 113-149. 

 A good map of the county makes clear the great number of lakes 

 which it contains, and the large amount of swampy area. It would have 

 helped to have also indicated the tamarack areas. A description of the 

 topography of the county and an account of the work done upon which 

 the list is based, wnth acknowledgements, is followed by the annotated 

 list of 202 species, 8 of which are given as hypothetical. There are 15 

 Residents, 7 Winter residents, 69 Summer residents, 79 Migrants, 11 

 Migrant and summer residents, 7 Migrants and winter residents, aud 6 

 Eare visitants. These various groups are given in separate lists in a 

 recapitulation at the close of the paper. The author has evidently taken 

 pains to make certain of the identification of each species before giving 

 it place. In this he is to be commended. There are four good halftone 

 plates from photographs, each plate containing two pictures. Probably 

 the author is not responsible for the capitalization of the part of the 

 compound words which follows the hyjihen. This is consistently done 

 throughout the paper. We are glad to have this faunal local list.

 By Arthur A. Allen. From Abstracts of Proceedings, Linnaean 

 Society of New York. Nos. 24-25, 1911-13. Pages 41-128. 

 We have seen few jjapers which can compare with this one in thor- 

 oughness of the work done, interpretation of the facts gathered, arrange- 

 ment of the material, selection, and makeup. The numerous halftones 

 from photographs are not only unif(n-mly good, but tiiey tell something
