BIRDS OF BRITISH BURMAH. 
that B. rafflesi is inseparable from B. flaviventris. Prinia super ciliaris of 
Salvadori (Ucc. Borneo^ p. 249) is probably the same species, as the 
present bird varies much in coloration,, especially with regard to the eye- 
streak and the sides of the head. The superciliary streak is generally present 
in birds shot in the cold weather, but not always. It is probably due both 
to season and age combined, only the very old birds perhaps acquiring it. 
The Yellow-bellied Wren- Warbler is very abundant in the marshes near 
Rangoon. I have observed it to be very abundant in the plains lying 
between the Pegu and Sittang rivers, as far north at least as Paghein. 
Mr. Davison procured it only in the extreme south of Tenasserim ; but 
it will probably be found to occur throughout the whole Division in 
suitable localities. 
It is spread over Northern India, more or less along the base of the 
Himalayas, up to Scinde, and it is found in Bengal and the eastern hill- 
tracts of that province. It has occurred in Singapore and in Sumatra, 
and Dr. Tiraud gives it from Cochin China. 
This species wherever it occurs is very plentiful. Generally, when 
engaged in seeking food, it threads its way through bushes and grass, and 
is seldom seen ; but at frequent intervals it mounts to the top of a tall 
reed and utters a short merry song, and then suddenly plunges into cover 
again, with a peculiar loud-sounding snap of the bill. I have frequently 
found the nest from May to September. It is an oval cup-like structure 
made of vegetable down and the flowering ends of the finer grasses, held 
together by grass. It is generally placed near the ground, and attached 
to two or three stems of elephant-grass. The eggs are brick- red in colour 
and generally four in number.
