OF WESTERN AFRICA. 
peckers known till now in Western Africa, belong to the smaller 
and more unobtrusive species of this form. The Cuckoos appear 
with thirteen species of the genera Indicator, Centropus, Zan- 
clostomus, Cuculus, Owylophus, and Chaleites. A species of this 
latter genus, Ch. smaragdineus, ranges with the most beautiful 
birds of Africa; at the same time, only very few of the West 
African Scansores occur in North-east, and still fewer in South 
Africa. The doye form is represented by fourteen species, the 
most numerous belonging to the genera Zreron, Turtur, and 
Peristera. Only five of these appear to be peculiar to Western 
Africa; among them, the Turtur simplea, discovered by Weiss, 
and the Peristera puella, Schleg., very striking from its dark 
blood-red colouring. In the order of Gallinaceous birds, the genus 
Numida appears in the foreground, with some very beautiful 
and marked species, NV. vulturina and cristata, A third species, 
N. rendallii, the most common in Senegambia, is distributed oyer 
the Cape de Verd Islands. West Africa is poor in the species 
of Francolinus and Pterocles. The dwarf form, Ortyzelos, is 
exclusively peeuliar to it. Coturniz histrionica, the species of 
Quail discovered by Weiss on the Island of St. Thomas, may ul- 
timately prove identical with the South African C. delegorguei. 
Bustards do not find their peculiar kind of country on the west 
coast of Africa; Otis denhamé only occurs far in the interior. No 
order, next to the Passeres, is so rich in species in Western Africa
