ZOOLOGICAL GEOGRAPHY. 
[part III 
open to observation; and that these are often of wide-spread 
types, and some few almost exclusively African. The facts he 
adduced do not, however, seem to have satisfied the objectors ; 
and as the subject is an important one, I will here give lists 
of all the genera of Passeres, Picarise, Psittaci, Columbse, and 
Gallinse, which inhabit the sub-region, leaving out those which 
only just enter within its boundaries from adjacent sub-regions. 
These are arranged under four heads: — 1. Oriental genera; which 
are either wholly confined to, or strikingly prevalent in, the 
Oriental region beyond the limits of the Indian peninsula. 2. 
Genera of Wide Eange ; which are fully as much entitled to be 
considered Oriental or Palaearctic as Ethiopian, and cannot be 
held to prove any Ethiopian affinity. 3. Palsearctic genera ; 
which are altogether or almost absent from the Ethiopian region. 
4. Ethiopian genera ; which are confined to, or very prevalent 
in, the Ethiopian region, whence they extend into the Indian 
peninsula but not over the whole Oriental region. The last are 
the only ones which can be fairly balanced against those of the 
first list, in order to determine the character of the fauna.
