complete as possible^ and the result is a work wLieh can 

 be recommended to our readers as an admirable compendium 

 of our knowledge of a part of the country which includes 

 much of the Rocky Mountains. It will also be useful to 

 dwellers in America as a reliable manual of the Ornithology 

 of a State^ which has only been treated hitherto by W. W. 

 Cookcj from a somewhat different point of view. 



JNIr. Sclater is evidently anxious that his book should be 

 in the hands of all local naturalists, and he gives for tlieir 

 use Keys to the Orders^ Families^ Genera and Sj)ecies^ which 

 are arranged and named as in the A. O. U. Check-list. 

 Another feature consists in the paragraphs of references to 

 local works on the A\ifauna, while full descriptions of the 

 Birds and short but suthcient notes on their habits follow 

 in due course. 



The physical features of Colorado with its lofty mountains, 

 its canons, })rairies and great upland " parks,'^ are described 

 in an interesting Introduction, which jjrocecds to an analysis 

 of the Bird-fauna as compared with that of other regions. 

 392 species are recognised, divided into 225 regular breeders, 

 resident or otherwise, and 117 non-breeders. Full lists are 

 given under each category, and an attempt is made to 

 delineate their vertical distribution. 



Three species which breed regularly above the timber-line 

 are of especial interest : Leucosticte australis, Anthiisrvbes- 

 cens, and Ltujopus leucurits; while many of the photographs 

 help us to realize the details in the letterpress. The articles 

 dealing with the Ducks and Grouse may be mentioned in 

 particular, as also those on the Wild Turkey and on the 

 habits of the Least Bittern, The spread of the English 

 Sparrow and the curious distribution of the JMugpie should 

 also be noted.
