Anderson's figure of H. yunnanensis (Anat, & Zool. Hes. 

 Yunnan, 1878, p. 656, pi. 50), though otherwise fairly good, 

 does not indicate the quadrate black spot on the malar 

 region beneath the ear-coverts which is present, to a greater 

 or less extent, in all the above series.

Both this species and H. hildebrandi Hume (Stray Feath. ii. 

 1874, p. 508) are very rare in collections and seem also very 

 closely allied, the former differing from the present one only 

 in the tint of the head, which is described as deep blackish 

 brown, while in H. davisoni it is rich warm brown. We 

 have followed Oustalet in identifying the above series with 

 the last-named form. 



114. Hemixus tickelli griseiventer, subsp. nov. 



Differs from Hemixus tickelli peracensis Hart. & Butl. 

 (Nov. Zool. V. 1898, p. 506), from the mountains of the 

 Malay Peninsula, in having the head rather duller brown, 

 ear-coverts more greyish, and underparts greyer with prac- 

 tically no fulvous suffusion on the breast and sides of the 

 body. 



'' Iris crimson, bill blackish, feet brown.''
