CATALOGUE OF CANADIAN BIRDS. 51 



Bonasa umbellus sabini. 



OREGON RUFFED GROUSE. 



This is the form of the " Birch Partridge " that is found on 

 the Pacific coast. It occurs in British Columbia, from the summit 

 of the Cascades to the sea-shore, and on the islands along the 

 coast. 



Lagopus lagopus. 



WILLOW PTARMIGAN. 



This species occurs from the Atlantic to Lake Winnipeg, and 

 north to the Arctics. It is very abundant at Point des Monts, 

 P. Q., and occurs at Sault St. Marie ; but the only specimens that 

 are known to have been taken south of the St. Lawrence are one 

 captured in the Magdalene Islands ( Cory}, and another in Lewis 

 County, N. Y. (Merriam}. In Dr. HALL'S list of Montreal birds 

 it is given as rare, but later observers have failed to procure any 

 evidence of its occurrence in that vicinity, though Mr. NIELSON 

 has found it near Quebec, and Dr. BRODIE reports it from thirty 

 miles north of Toronto. It is probably most abundant in Labra- 

 dor and in the Hudson's Bav district. 



ALLEN'S PTARMIGAN (Lagopus lagopus alleni) is a form of the 

 Willow Ptarmigan that occurs in Newfoundland only. 



Lagopus rupestris. 



ROCK PTARMIGAN. 



TURNER reports this as abundant on the treeless area of 

 Labrador, where it remains the entire year, and Dr. BELL found 

 it in vast numbers around Hudson's Strait. It has been taken 

 near Quebec {Couper} ; at Sault St. Marie {Mcllwraitli] ; and 

 on Anticosti {Brewsler).
