ART. 7 BIEDS FEOM YUNNAN AND SZECHWAN, CHINA — EILEY 37 



P. r. similis was formerly recorded as P. r. iakeri *^ from Yunnan, 

 following Rothschild's earlier papers, as no authentic specimens from 

 Burma were available for comparison. 



113. POMATORHINUS ERYTHROGENYS DEDEKENSI Oustalet 



Pomatorhinus macciellandi var. dcdekcnsi Oustalet, Ann. Sci. Nat. Zool., 

 ser. 7, vol. 12, pp. 276, 304, 1892 (Tsonghai, Tibet and Tatsienlu, 

 Szechwan ) . 



Thirteen adults, both sexes, northwest Yunnan (Likiang Moun- 

 tains, January-February and October; Yulo, 7,000 feet, August; 

 Ndamucho, 14,000 feet, October) ; two males and six females, south- 

 west Szechwan (Muli Valley, 10,000 feet, June; Muli Mountains, 

 10,000 feet, June; Mount Mitzuga, 12,500 feet-13,000 feet, Muli, 

 June; Dzampe 14,000 feet, Muli, July; Djago, 11,200-12,000 feet, 

 April; Tatsienlu, 9,500-10,000 feet. May); one female, without 

 locality. 



The variations in a large series of this race are considerable. The 

 specimens taken in the winter are light brownish olive above; by 

 summer they become hair brown by fading. The male has a longer 

 bill than the female. Three adults from Tatsienlu taken in the 

 breeding season do not differ appreciably from three adults taken 

 at the same season in Muli. 



In reporting on Doctor Rock's former collection from Yunnan *^ 

 four specimens from the Mekong Valley were listed without specific 

 comment. These four specimens have the black streaks on the chest 

 very pronounced, especially in a male, U. S. N. M. No. 296712, which 

 has even the breast spotted quite heavily with black spots, but as 

 some of the specimens from farther north approach the lightest 

 marked Mekong Valley specimen very closely, these heavily streaked 

 birds had better be regarded as individual variations for the present. 



Two females from Mount Mitzuga are evidently birds of the year 

 in nearly adult plumage; their bills are remarkably short, 23 and 24 

 mm. against an adult measurement of 32-35.

Trochalopteron elliotu Verreaux, Nouv. Arch. Mus. Paris, vol. 6, Bull., p. 36, 

 1870 (mountains of Chinese Tibet). 



Twelve males, eight females, and one immature not sexed, north- 

 west Yunnan (Likiang Mountains, January-February, and Septem- 

 ber; Mountains of Yungning, 12,000-13,000 feet, November-Decem- 

 ber; Ndamucho, 14,000 feet, October; Luddii Mountains, 12,000- 

 13,000 feet, August) ; 11 males and 6 females, southwest Szechwan
