Major Allan Brooks contributes a list of the Wading- 

 birds of southern British Columbia. He believes that no 

 group of birds has been so neglected by western ornitho- 

 logists, and that there is still much to be learned about 

 them. Mr. Grinnell, the Editor, argues that the life of the 

 sea-birds must be a comparatively safe one, as most of 

 the species only lay one or at the most two eggs, and seldom, 

 if ever, rear a second brood, and if the numbers remain 

 constant it shows that the struggle for existence cannot be 

 very severe. 



Mr. Grinnell also describes a new subspecies of Brewer's 

 Blackbird separating those from the Pacific slope from those 

 of eastern North America under the name Euphayas cijauo- 

 cephalus laiiiusculus. Mr. H. Oberholser has a new race of 

 Shore-Lark, Otocoris alpestris sierrce, breeding in the Sierra 

 Nevada of California, and Mr. W. P. Taylor a new race of 

 Ptarmigan, Lagopus leucurus runierensis, from Mt. Ranier, 

 in Washington State, where it lives at an elevation of from 

 6000 to 8000 feet.

This excellent magazine, edited by our foreign membez-. 

 Dr. Lonnbergj deals with zoology and botany in all its aspects, 

 as its title implies ; but there is a good proportion of articles 

 on bird-life, chiefly, of course, of local interest, such as rare 

 occurrences and lists of birds of special districts in Sweden. 

 There are also a good many articles of more general interest. 

 Such is the series by Mr. L. Cx. Andersson containing an 

 account of the travels of Carl Thunberg to South Africa 

 in 1770-1779, an article on bird-psychology by Mr. A. 

 Adlersparre, and several by Dr. Lonnberg himself. Two of 

 these deal with a large collection from Mongolia and north- 

 west China which have recently reached the Stockholm 

 Museum from Mr. P. J. G. Anderson, and another on
