4. ETHIOPIAN GENERA OCCURRING IN CENTRAL INDIA. 
Thamnobia, Pyrrhulauda, Pterocles, Francolinus ;—4 genera. 
A consideration of the above lists shows us, that the Hindostan 
sub-region is by no means so poor in forms of bird-life as is 
generally supposed (and as I had myself anticipated, it would 
prove to be), possessing, as it does, 151 genera of land-birds, 
without counting the Accipitres. It must also set at rest the 
question of the zoological affinities of the district, since a pre- 
ponderance of 88 genera, against 4, cannot be held to be insuffi- 
cient, and cannot be materially altered by any corrections in 
details that may be proposed or substantiated. Even of these 
four, only the first two are exclusively Ethiopian, Pterocles and 
Francolinus both being Palearctic also. It is a question, indeed, 
whether anywhere in the world an outlying sub-region can 
be found, exhibiting less zoological affinity for the adjacent 
regions ; and we have here a striking illustration of the necessity 
of deciding all such cases, not by examples, which may be so 
chosen as to support any view, but by carefully weighing and 
contrasting the whole of the facts on which the solution of the
