 other specialists. 



Swarth's list is a very acceptable piece of work and one of which he may 

 well feel proud, while students of the ornithology of the southwestern por- 

 tion of our country will find it a reliable guide to the ornis of one of the 

 most interesting states, zoologically speaking, of the entire Union. — W .S. 



Aiken and Warren on the Birds of El Paso County, Colorado. » — 



This is an admirably prepared annotated list of 276 species, with an 

 introductory discussion of topography, life zones, analysis of the bird fauna, 

 workers in the region and a bibliography. The forty-five half-tones are 

 from photographs from nature, all but two by Mr. Warren, and furnish 

 good illustrations of many birds as well as nests and eggs. 



We learn from the introduction that Dr. J. A. Allen was the first orni- 

 thologist to visit El Paso County, his report pubUshed in 1872 being the 

 first list of Colorado birds. Mr. Aiken the senior author of the Ust came 

 to Colorado Springs in 1871 and his collection begun soon after his arrival, 

 is now in Colorado College. Mr. Warren's residence dates from 1881.

Why a paper of this sort should be pubhshed in two parts both of which 

 were printed and distributed apparently at the sarne time, and why both 

 parts are numbered, " 13 " in one series and " 74 "and " 75-76 " in an- 

 other, are problems that only those in charge of the Colorado College 

 pubUcations can explain, while to others they will prove a source of 

 annoyance and comphcation. — W. S. 



Mathews' Birds of Australia.^ — With part 6 the third volume of this 

 great work is brought to a close completing the Herons and Bitterns. The 

 high standard of the previous volumes is fully maintained and so thor- 

 oughly has the author covered the subject of nomenclature that we find 

 but one new name dating from this part, i. e. Hemigarzetta (p. 448) a 

 new generic term for Herodias eulophotes Swinhoe. — W. S. 



Bannerman on the Ornithology of the Canary Islands.^— In this 

 admirable paper Mr. David A. Bannerman gives us a most interesting 

 account of his visit to this island group and a careful discussion of the birds
