“Tris hazel, or brown, sometimes red, bill black, slate or 
lead, base pinkish, feet yellowish brown or dirty wax yellow 
tinged with green. 
Comparison of series of these Golden-headed Babblers 
from different localities is rendered difficult by the fact 
that the skins fade with great rapidity, especially the 
clear yellow on the crown and on the undersurface. It 
is evident, however, that specimens from the Nepal and 
Sikkim Himalayas, Stachyris chrysaea chrysaea, Hodgs., are 
much clearer yellow above and below than any of the allied 
forms. Stachyris chrysaea asstmilis from Karen-nee, ranging 
down to Central Tenasserim, (Walden, in Blytl’s Birds, Burma, 
p. 116 (1875)), is a duller bird, especially above, with the 
streaks of the crown: less marked. From this form, 
Stachyris chrysops, Richmond (Proc. Biol. Soc. Washington 
XV, p. 157 (1902) ), described from Trang, in the north of 
the Malay Peninsula, is doubtfully distinct. It was sent by 
its describer to Dr. Sharpe, ‘‘ who considered it new and 
closely related to S. chrysaea.”’ 
No comparison seems to have been made with S. assimzlis, 
from which the actual specimen of S. chrysops, being a fresh 
skin, probably differed markedly in strength of tint. The 
F.M.-S. Museums possesses very large series of specimens 
from both north and south of the locality of the type specimen 
of S. chrysops, with which some have been compared and 
found to agree perfectly, and we fail to see in what particular 
they differ from S. assimilis; pending actual comparison of 
freshly collected material from Tenasserim, we have, however, 
left the Malayan Peninsula form under Richmond’s name, 
which, at the most, is only of subspecific value. 
The large series of the Sumatran form listed above, shows 
that it, too, is very slightly differentiated from the Malayan 
form, from which it can perhaps be separated by a slightly 
larger bill and generally darker and more intense colouration, 
the sides of the breast and flanks especially being strongly 
suffused with dusky olive.
