PYCNONOTIDÆ.

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.


Genus TRICHOLESTES Salvadori, 1874.

The genus Tricholestes is remarkable for the numerous long hairs which spring from the back; these hairs lie close to the feathers and are not distinctly visible until they are lifted up.

In Tricholestes the bill is very strong for the size of the bird. The culmen is straight for half its length and the tip of the upper mandible is strongly tipped and notched. The frontal and rictal bristles are long. The head is not crested. The wing is blunt, the tail slightly rounded and the feet are exceedingly small and weak.
