216 GEOLOGICAL SURVEY OF CANADA. 
CXXVII. LOPHORTYX. Bonaparte. 1838. 
294. California Partridge. 
Lophortyx californicus (SHAW) Bonap. 1838. 
Vancouver island. Introduced from California. (Fannin.) They 
were quite numerous in the autumn of 1892, but the winter of 1892-93 
being very severe a great number died. They have increased 
rapidly since and in the autumn of 1906 were very abundant 
near Victoria, Vancouver island. (Spreadborough.) 
CXXVIII. DENDRAGAPUS. ELLior. 1864. 
297. Dusky Grouse. 
Dendragapus obscurus (SAY) ELLioT. 1864. 
We have no specimens of this grouse in our collections, nor are 
we sure that this form occurs in Canada. It is more than probable, 
however, that it is partly the blue grouse of southwestern British 
Columbia. In the United States it has been taken in Montana and 
Idaho and hence may cross the British Columbia boundary. 
297a. Sooty Grouse. 
Dendragapus obscurus fuliginosus RipGw. 1885. 
On my arrival on the coast of British Columbia, in the month of 
April, 1889, the calls of this species could be heard nearly through- 
out the day. (Streator.) West of the Coast range, in British 
Columbia, including all the larger islands, an abundant resident. 
(Fannin.) Abundant on the western slope of the Coast range, B.C. 
(Brooks.) Common in all parts of Vancouver island; begins to call 
about April 1st ; quite common at Hastings, B.C., in April, 1889, 
when it made the woods resound with its almost constant calls. 
Common along the international boundary from Whipsaw creek 
west to Chilliwack, B. C., in 1905 ; rare on the mountains along 
the Chilliwack river, B.C., in 1906. (Spreadborough.) Bischoff 
secured seven of these birds in the vicinity of Sitka, and 
Hartlaub records it from Portage bay. There is no doubt that this 
bird occurs considerably farther north than Sitka along the coast 
region. (Nelson.)
