Mr. W. R. Ogilvie Grant on Birds 
I am inclined to believe that the Tonracos seen in the Dabous 
valley belong to a different species, the white and red 
marking on the head appearing slightly different. Owing to 
the want of cartridges, I had no opportunity of verifying 
this ; but I mention the fact for the benefit of future 
travellers.—L.]

Iris red ; bill and legs black-brown. 
The immature male (specimen a) is referred to this species 
with some doubt; the bill is slightly smaller than that of 
the female, and though the upper tail-coverts are barred 
with buff, the wings and the rest of the plumage show no 
trace of immaturity; the top of the head and back of the 
neck are, moreover, dark green, with a slight purplish-blue 
tinge on some of the feathers. This difference in colour 
may, however, be due to w r ear.
