When this paper was begun, in 1881, the first of these states formed 
the eastern boundary of our Asian Empire. The author wished, there- 
fore, to compare its avifauna with that of the extreme western point — 
Sindh — which he had already worked out. The species found in Manipur 
only are distinguished by different type, but reference is also made to 
those occurring in British Burma, as well as in the other provinces men- 
tioned in the title. Notes are added by J. R. Crtpps, who was employed 
as a collector in the district.

This useful work contains a concise description of each species which 
may fairly be considered British, though several American land-birds 
are omitted. The nomenclature and arrangement of the B. O. U. List 
has been followed in the main, while the status of each Bird is indicated 
by letters in brackets.
