180 SOME CHINESE VERTEBRATES. 
It can be separated at once from O. subaffinis by the lemon-yellow underparts, 
under wing-coverts, and superciliaries; by its darker more olive-green back, 
and by the smaller amount of black on the lower mandible. It was probably 
a stray migrant. ' 
It does not seem possible that it can be O. bianchi Sharpe (originally described 
by Berezowski and Bianchi as O. davidi) which we consider, though without 
specimens, to be much nearer to, if not the same as, O. subaffinis. 
OREOPNEUSTE FUSCATUS (Blyth). 
Eight specimens, both sexes, Ichang, Hupeh, autumn — September 27 to 
November 28 — and one killed March 22. 
OREOPNEUSTE ARMANDI (Milne Edwards). 
Three adults, one male, two females, Tachienlu, western Szechwan, 9,000 
to 10,000 feet, July. 
REGULOIDES MACULIPENNIS DEBILIS, sub. sp. nov. 
Two adult females, western Szechwan; Kiating, November 26, and Luluping, 
November 8. 
Type:—No. 52502 M. C. Z. adult 9. Western Szechwan: Kiating, 
November 26, 1908. W. R. Zappey. 
Characters:— Similar to true R. maculipennis (Blyth) of the Himalayas, 
but head mouse-gray instead of brownish olive; back bright olive-green instead 
of yellowish or greenish olive; throat paler, grayish white instead of dull drab- 
gray; belly paler and purer yellow — pale sulphur-yellow, instead of dull oliva- 
ceous maize-yellow. 
Measurements:— Type, adult 9°, wing, 48; tail, 33; tarsus, 16; culmen, 7. 
Remarks: — This is another very distinct west China subspecies of a ~ 
Himalayan species. It probably breeds in the coniferous forest on Washan 
and perhaps in other parts of this elevated region, although it was not taken 
during the breeding season. 
REGULOIDES PULCHER (Blyth). 
Three specimens, two males and a female all adults, Washan, Yachiakun, 
and Tachiao, western Szechwan, 11,000 to 12,000 feet, June, and July.
