A NEW DRYONASTES FROM SZECHUAN, CHINA. V^^, 



BY J. H. RILEY. 1 



In a small collection of birds, mostly from Mount Omei, 

 central Szechuan, China, presented to the U. S. National 

 Museum recently by the Reverend David C. Graham, the 

 following very distinct species of Dryonastes was included. As 

 it apparently agrees with no published description, I take 

 great pleasure in naming it after the donor : 



Dryonastes grahami, sp. nov. 



Type, adult male, U. S. National Museum, No. 257,204, Shin Kai Si, 

 Mount Omei, Szechuan, China, July 6, 1921. Collected by David C. 

 Graham. 



General color above and below, deep neutral gray, mouse gray on the 

 throat and jugulum; forehead and a narrow line bordering the black mask, 

 light neutral gray; feathers covering the nostril, supra-loral streak running 

 back beyond the eye as a narrow line, lores, sub-orbital and malar regions to 

 posterior border of the eye, and chin, black, forming a mask; ear-coverts 

 and an irregular patch on sides of neck, overlapping slightly as a narrow 

 streak the posterior extension of the black subra-loral streak, white, the 

 ear-coverts tinged with grayish anteriorly; upper and under tail-coverts, 

 mouse gray; wing-coverts similar to the back; remiges, chaetura black, 

 edged on the outer web with deep mouse gray; tail, sooty black; narrow 

 border of feathers surrounding anus, white. Wing, 130.5; tail, 140; cul- 

 men, 25; tarsus, 46; middle-toe, 27 mm. 



Remarks. — In structure and size the present species agrees fairly well with 

 Dryonastes perspicillatus (Dryonastes as at present constituted is not a very 

 homogeneous genus), but not in color. The black mask of Dryonastes 

 grahami only differs in detail from that of Dryonastes perspicillatus, but the 

 white on the ear-coverts and sides of neck and gray plumage of the former 

 make it very distinct and quite unlike any described species known to the 

 author.
