Sylviparus modestus simlaensis, subsp. nov. 
Much brighter and paler than S. m. modestus Burton, and 
a fortiori than S. m. saturatior Rippon. 
Type. B.M. No. 86.11.1.473. A. L. Davidson, Simla. 
220x808 | 
This newly described subspecies appears to be found from 
Simla extending N.W. into Kashmir; S. m. modestus is 
found from Garhwal to Sikkim, whilst the Burmese and 
Chinese forms are all Rippon’s S. m. saturatior. 
Parus dichrous wellsi, subsp. nov. 
This form differs from P. d. dichrous and P. d. dichroides 
in being much darker above and paler, more buff than 
rufous below. ; 
Type. No. 1906-12.17.397. 
Hab. W. Yunnan, Yangtse big bend. 
I have named this bird after Mr. Thomas Wells in 
recognition of the great help he has rendered me in working 
out these birds. 
Garrulax moniliger leucotis, subsp. nov. 
This form has long been distinguished by many naturalists 
from the Northern and Indian form, but appears never to 
have been given a name. It differs at a glance from the 
Indian form in having the whole or practically the whole 
of the ear-coverts white, whereas the Indian birds have 
them black with merely a small white centre. The tips to 
the tail-feathers are broadly rufous-buff in the Siam bird 
and pure white in the Indian.

Eupetes macrocercus griseiventris, subsp. nov.
