larger, extending on the three outer pairs to both webs ; the abdomen is 
uniformly red or washed with pale white, not with aureous ; the wing-spot 
is conspicuous, not being hidden by the wing-coverts j each feather of the 
tertiaries has a long narrow red spot at its extremity ; and the rump is 
obsoletely barred with black ; it is also smaller than C. macrorhynchm . 
The Allied Broadbill is restricted to Arrakan and the south-western 
portion of Pegu. Mr. Blyth received specimens from the island of Ramree, 
and I procured this bird on the Arrakan hills near Nyoungyo. It pro- 
bably extends down to Cape Negrais. It appears to be common in some 
portions of the Irrawaddy Delta, for Capt. Raikes observed it round about 
Yandoon, and I have myself examined a specimen said to have been killed 
near Rangoon. 
I have had no opportunity of observing its habits.
