Description. — Male and female. The plumage is the same as in H. frontalis 
and the birds only differ in size : the white in some specimens is confined 
to the forehead only ; but this is not a sexual difference^ for in the allied 
H. frontalis a sexed female had the white extending to the crown. The 
narrowness of the white is probably due to youth. 
Length 11 inches, tail 6'7, wing 4-2^ tarsus 1-3, bill from gape I'l. 
The Larger Black-backed Forktail was met with by Mr. Davison in 
various places in Tenasserim from Kollidoo down to Meeta Myo. It 
seems to be confined to the rivulets of the denser evergreen forests below 
2500 feet elevation. 
It extends into the mountains of Southern China up to Hoangho and is 
a resident there. It has been observed also in the Lushai and Dafla hills 
and in Assam. 
Southwards it ranges down the Malay peninsula to Java. It probably 
occurs in Sumatra. 
Birds from China and J ava appear to me to be inseparable.
