This is the largest of the East African Francolins, and was 
first met with in August 1889, in the bamboo-zone on the 
northern outskirts of Kikuyu, at an altitude of 8000 feet. It 
is very plentiful on the Aberdare Range, and is also found in 
the forests of the Sabugo o-lol-tian, Laikipia. On the western 
side of the Aberdare Range it is plentiful in the thick patches 
of nettles and scrub that mark the sites of old Masai manyattas, 
and extends as far north as Il-polossat lake. So far as is 
at present known it is not found on the west side of the Rift 
Valley. It is usually found in small coveys of from three to 
five individuals, of which, I believe, one only is a cock bird. 
As a runner it is equalled only by the ‘ Spur-fowl.’ When 
flushed it will often fly up into a tree or bamboo. 
Male. — Forehead and cheeks dull red; chin, throat and 
sides of the neck white, with narrow rufous shaft-streaks ; 
chest, breast flanks and upper back chestnut with white 
margins to the feathers ; abdomen dusky grey ; under
