become naturalized and abundant throughout the settled parts of 

 Vaucouver Island. 



87. Dendragapus obscurus fuliginosus. Sooty Grouse. 



Abundant everywhere and at all elevations west of the Cascades. 

 This form reappears on the higher areas of increased rainfall 

 between the Rocky Mountains and Cascades in British Columbia. 



88. Dendragapus obscurus richardsonii. Richardson's Grouse. 



Everywhere throughout the interior of British Columbia. A 

 complete series of this race from all parts of British Columbia com- 

 pared with a like series of fuliginosus will be likely to present cer- 

 tain facts of distribution and differentiation quite at variance with 

 our present view of the subject. 



89. Dendragapus franklinii. Franklin's Grouse. 



Numerous on the slopes and summits of the higher mountains of 

 the mainland to and including the Cascades and Rockies. On the 

 Cascades as far south as Nachess Pass, Washington. 



90. Bonasa umbellus togata. Canadian Ruffed Grouse. 



91. Bonasa umbellus sabini. Oregon Ruffed Grouse. 



Specimens from districts between Cascade and Rocky Mountains 

 in British Columbia are pretty uniformly colored, one male alone 

 showing red phase of sabini. Intermediates nearly connect the grayest 

 coast specimens of sabini with darkest examples of togata from the 

 interior. A male sabini from Lulu Island has a nearly typical 

 togata tail. I find no eastern specimens in the Academy's collection 

 comparable in grayuess with any from British Columbia or Wash- 

 ington. 

 *92. Bonasa umbellus umbelloides. Gray Ruffed Grouse. 



Of the Ruffed Grouse found in the Rockv Mountains at Field I 

 failed to secure specimens. Mr. Fannin classes them as umbelloides. 



93. Lagopus rupestris. Rock Ptarmigan. 



Summits of Cascades, Clinton, Lac La Hache; also on summits 

 of Rocky Mountains, Field, Hector, Ottertail. Abundant, descend- 

 ing to 4,000 feet in winter. 



*94. Lagopus leucurus. White-tailed Ptarmigan. 



Residents inform me this species is also found sparingly in winter 

 in Kicking Horse Pass, British Columbia. One obtained at Hector 

 examined. Reported from Soues Mountain, Clinton, by Mr. Jos. 

 Smith, also from Mount Tacoma, AVashington ; Edwards Bros.
