" Although specimens from northern Ontario and middle Quebec average slightly 

 darker and have a greater proportion of the tarsus unfeathered than typical 

 umbelloides from the east slopes of the Canadian Rockies, the difference seems to 

 be too slight to recognize as a distinct subspecies. These characters merely indicate 

 the trend toward intergradation between umbelloides and iogata. Therefore, 

 canescens Todd becomes a synonym of umbelloides. Ruffed grouse recorded farther 

 east in Quebec (Anticosti Island, Natashquan, and Wolf Bay) and in south- 

 eastern Labrador (Hamilton Inlet and Sandwich Bay) may belong to this race 

 also, but no specimens from these regions have been examined in the present study. 



Specimens from southern Manitoba (Shoal Lake and Carberry) are intermediate 

 between umbelloides, incana, and mediana, but on average characters, particularly 

 relatively short unfeathered tarsus, they seem a little closer to umbelloides.
