308 GEOLOGICAL SURVEY OF CANADA. 



Saw two near Elko, B.C., May 14th, 1904, and two young half- 

 grown May 2otli. Also observed this species at Midway, Meyer 

 creek, Sidley and Skagit river, B.C. (Spreadborough.) Mr. Ander- 

 son collected an adult male on Sheep creek and another at Caribou 

 camp, Kenai peninsula, Alaska, which are referred here by Mr. 

 Chapman. 



Breeding Notes. — A fane skin of the dark-coloured race of the 

 genus Bubo with the two eggs was collected for me by Mr. Dicks at 

 Sandwich bay, Labrador. The eggs were taken May ist, 1896, and 

 the nest was built in the top of a spruce, a large structure of sticks, 

 weeds and rubbish. (W. Raine.) April loth, 1903, at Penticton, 

 B.C., I found a nest in a cluster of branches growing from the trunk 

 of a large cotton- wood tree. It was made of a large bundle of sticks 

 and contained two nearly fresh eggs. I am not sure of this bird. 

 It is rather dark for the western and not dark enough for the dusky.

Note. 



Mr. H. C. Oberholser in Proc. U. S. Nat. Mus. xxvii, 1904, p. 177- 

 192, has pubhshed a revision of the American great horned owls 

 which were it followed here would make necessary many changes 

 in the names of the varieties known to occur in Canada and a re- 

 arrangement of the geographical limits given them in the first 

 edition of this catalogue. As most of the published citations refer 

 to specimens which we have not seen, the old arrangement has been 

 retained but the names and distribution of the several forms as 

 given by Mr. Oberholser are printed below. So many observers 

 record two or more intermediate forms from the same locality that 

 it is almost certain that yet further changes will have to be made 

 in the geographical distribution given by Mr. Oberholser. 



Great Horned Owl. 



Asio magellanicus mrginianus (Gmelin.) 

 Southern Canada and eastern United States, west to Ontario. 

 Mr. Oberholser cites no specimens from Ontario or the Eastern 

 States, and does not mention Quebec, Nova Scotia or New Bruns- 

 wick. We know that the species breeds in those three provinces 

 and we infer that either an undescribed form or the Labrador form 

 is the resident breeding variety.
