(886) Acanthopneuste trochiloides claudiae.
La Touche's Yunnan Willow-warbler.
Acanthopneuste trochiloides Claudia La Touche, Bull. B. O. C., xliii, p. 22 (1922) (Yunnan).
Vernacular names. None recorded.
Description. Similar to A. t. trochiloides, but practically white underneath, with just a tinge of oily-green; the under tail-coverts are yellow; the wing-bars well developed, and the coronal streak and supercilia conspicuous.
Colours of soft parts as in the other races.
Measurements. I make this out a much smaller bird than La Touche does. His series of specimens in the British Museum have wings ranging from 52 to 60 mm.
Distribution. Yunnan only so far as is known at present.
Nidification and Habits. Nothing recorded.
