Iris brown, legs dusky, soles and interstices between 

 the scales pale. The bill differs greatly in the two sexes. 

 In the male it is much larger and black, except one spot 

 below the nostril : in the female the upper mandible is 

 yellowish white towards the base, except around the 

 nostrils, where it is dusky; the lower mandible dusky 

 near the base, with one or two diagonal pale streaks ; 

 both mandibles reddish brown towards the tip. 



Not "very common about Komayli, at the foot of the 

 hills, in February; much more frequent in the Lebka 

 vaUey in July, and not rare in the Anseba. 



Like the others, this bird is often seen on the ground,^ 

 and is highly insectivorous ; coleoptera, ants, and seeds 

 being found in the stomach. Amongst the coleoptera in 

 one instance were several of a species of Molurus. At 

 another time I saw a bird of this species fly after and 

 capture a locust in the air. The Hombill was not very 

 skOful in hawking, and the locust eluded him at first, bu 

 was soon caught. 



It is not quite clear that this species is not distinguish- 



1 Brehm's observations on the Abyssinian Hornbills are opposed to miiie. 

 He says they rarely descend to the ground, that they feed on fruits, and that 

 the voice of difierent species is similar (" Reise nach Habesch," p. 357). I 

 examined the stomachs in numerous instances.
