I have not been able^ for want of specimens, to work np this difficult 
group of birds, and I therefore deem it better to follow the late Marquis 
of Tweeddale, who has written a most exhaustive monograph of the genus 
Batrachostomus, 
According to Lord Tweeddale, the names B. affinis and B. hodgsoni refer 
to the same species, and he also adds as a synonym B. castaneus, Hume. 
The accuracy of this latter identification, however, is, I think, open to 
doubt, and I do not adopt it. 
Only three specimens of Batrachostomus have been procured in British 
Burmah and Karennee by reliable collectors. The first was shot by the 
late Colonel Tickell near Tonghoo and is figured and described by him in 
his Illustrations of Indian Ornithology,^ vol. vii. ; the second was pro- 
cured by Capt. Wardlaw Ramsay in Karennee at an elevation of 6000 feet, 
and the third was obtained by Capt. Bingham in the Thoungyeen valley in 
Tenasserim. 
Colonel Tickell thus describes his bird : — " Iris sepia ; bill fleshy horn; 
legs horn. Head, upper back and scapulars bt. umbre, shaded ferruginous 
on back and mingled with greyish on scaps. : the whole vermiculated 
crossways, black. Outer webs of two or three largest scapulars white 
bordered with black. Tertials clouded brown, ferruginous and grey, with 
black vermiculations. Wing- coverts rusty vinous, broadly vermiculated 
black. Secondaries and primaries, outer webs chestnut rusty with broken 
narrow bars of black. Inner webs sepia. Tips of primaries pale and 
mottled. Tail cinnamon-brown, shaded gray marginally and vermiculated 
black, and crossed with five paler bars (not joining the shafts) , subterminal
