Silver Pheasant (6r. nycthemerus), in which the wliite greatly 

 preponderates over the black. The Kalij group inhabits 

 areas of dense forest, low elevation and heavy rainfall; the 

 grey birds higher but moderate elevations, mixed forest and 

 grass-lands ; the white birds the highest plateaus, chiefly 

 grass-covered, where the rainfall is light or scanty. 



It is the interaction of these factors — temperature, 

 humidity, elevation, and vegetable growth — that has brought 

 about the great differentiation of forms in the genus Genncens 

 which we find in Burma ; and. in this paper, which is 

 illustrated with two maps and three plates, the course of 

 evolution is clearly traced in the introductory portion, which 

 is followed by a thorough systematic revision. 



Taverner on the Canadian Cormorant and the Salmon. 



[Tlie Double-crested Cormorant {Phalacrocorax auritus) and its relation 

 to tlie Salmon Industries on the Gulf of St. La^Yrenc■e. By P. A. Tav- 

 erner. Canada Dept. Mines, Geol. Surv. Mus. Bull. no. 13, 19lo, 

 pp. 1-24.] 



Many complaints have recently reached the Geological 

 Survey of Canada, which also concerns itself with 

 questions and investigations of a biological nature, of the 

 depredations of the Cormorant {Phalacrocorax auritus) in 

 the salmon-rivers running into the St. Lawrence, along the 

 Gaspo Coast near its mouth. The Director of the Survey 

 accordingly deputed Mr. Taverner, accompanied by Messrs. 

 Young & Hennesey, to investigate this question. 



As a result of their enquiries and of the examination of 

 the stomachs of 3,2 Cormorants, they came to the conclusion 

 that there was little or no foundation for the complaints in 

 regard to the Salmon parr and smolts — the older Salmon 

 would certainly be immune from the attacks of the birds. 



The stomachs of the Cormorants examined contained 

 scul])in, herring, and other fish, but in no cases smolt or 

 2)arr, Avhich are both quick and agile fish and would be 

 unlikely to be caught by fishing bii'ds. 



Incidentally some account is given of the numbers and 

 life-history of the Cormorants.
