in central Montana, is varied in its physical features, its western portion 

 including several outlying spurs of the Rockj Mountains, with also two 

 rather isolated groups of mountains, the Judith and Moccasins, in its 

 central portion, while the eastern half is plains and ' bad lands.' The 

 elevation varies from three thousand to eight thousand feet. The bird 

 fauna is correspondingly varied, consisting of the usual species of the 

 northern plains region, with a mixture of alpine forms that extend east- 

 ward from the Rocky Mountains. 



The present list numbers 179 species, divided into: "Residents, 30 

 species ; summer residents, loi species; migrants, 31 species; winter 

 residents or visitors, 13 species ; otlier visitors, 4 species." 



The list is based partly on the author's observations made during several 

 years' residence in the county, and partly on the published records of 

 other observers. 'A Partial Bibliography of Montana Birds' occupies 

 three pages preceding the list, ' and there are two pages descriptive of 

 the topography and boundaries of the county. In addition to the usual 

 annotations, a short description (usually of two to four lines) is given of 

 each species, for the convenience of "teachers and others interested in 

 nature study." In many instances, in the case of the lesser known west- 

 ern species, much original biographical matter is included. The large 

 number of half-tones are from photographs of living birds, by Mr. E. R. 

 Warren of Colorado Springs, and of nests and eggs, by Prof. M. J. Elrod 

 of the University of Montana. An interesting feature of the work is its 

 publication as a special 'Bulletin' by the Board of Trustees of the Fergus 

 County Free High School, of which Mr. Silloway is the Principal, appar- 

 ently for free distribution to those interested, and as a part of the educa- 

 tive mission of the school. The list, while not presumed to be complete, 

 is believed to be as nearly so as present information will permit, and will 

 serve as an excellent basis for further investigation. — J. A. A. 



Oberholser's ' Review of the W^rens of the Genus Troglodytes.' ^ — The 

 strictly American genus Troglodytes^., as here defined, includes not only 

 the species usually heretofore referred to it, but also many West Indian 

 forms which have been commonly referred to TJn-yophilus. The one 

 exception of exclusion is the Troglodytes bro-wni Bangs, from the 

 mountains of Chiriqui, Panama, which is made the type of a new 

 genus Thryorchilus. Thirty-seven forms are recognized, of which 18 

 are given the "-ank of species, and 19 that of subspecies, three of the 

 latter being described as new. The status and nomenclature of the North 



'By a curious typographical error Coues is uniformly entered as "Coues, 

 Elliott B.," though the name is elsewhere correctly given. Also, on p. 36, 

 Melanerpes '■'■ erythrophthalmns'''' is evidently a lapsus for erythrocephalus.
