308 GEOLOGICAL SURVEY OF CANADA. 
Saw two near Elko, B.C., May 14th, 1904, and two young half- 
grown May 20th. 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 fine 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 rst, 1896, and 
the nest was built in the top ofa spruce, a large structure of sticks, 
weeds and rubbish. (W. Razne.) April roth, 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. 
(Spreadborough.) 
NOTE. 
Mr. H. C. Oberholser in Proc. U.S. Nat. Mus. xxvu, 1904, p. 177- 
192, has published 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 virgimanus (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.
