(383) Criniger tephrogenys grandis.
THE YUNNAN WHITE-THROATED BULBUL.
Criniger pallida grandis Stuart Baker, Bull. B. 0. C, xxxvii, p. 15 (1917) (Yunnan).
Vernacular names. None recorded.
Description. Upper parts olive-brown, the head browner; lower parts pale olive-yellow, the flanks olive-green and the under tail-coverts buff; the yellow is deeper and more olive than in pallida. Nearest to the Hainan form, C t. pallida but much bigger, with a wing 114 to 119 mm. as against 100 to 115 in that bird, according to Oustalet, or 98 to 105, according to the British Museum series.
C. t. henrici is intermediate in size but yellower on the under parts.
Colours of soft parts. Iris red; bill bluish grey, darker on tip and culmen ; legs fleshy-grey.
Measurements. The largest of all the forms of White-throated Bulbuls, with a wing 114 to 119 mm.
Distribution. Yunnan and N.E. Shan States. Siam birds seem referable to C. t. henrici, a smaller form in the South from Annam, Cochin China etc. Oustalet's larger birds from Yunnan should probably all be grandis.
Nidification and Habits not recorded.
