NO. 14 THE RACES OF PELLORNEUM RUFICEPS — ^DEIGNAN I7 



the sides of the neck broader and more conspicuous : the under parts 

 rather less extensively washed with buff. 



From P. r. shanense separable by having the brown of the upper 

 parts slightly more rufescent, less olivaceous; the dark centers to the 

 feathers of the uppermost back less strongly defined ; the light edgings 

 to the feathers of the sides of the neck narrower and less conspicuous ; 

 the under parts less extensively washed with buff — the throat and 

 center of the abdomen almost free of this color. 



Range. — Hilly regions of Yunnan, Haut-Laos, and Tongking, so 

 far as these lie between the Mekong River and the Black River-Red 

 River divide. 



Specimens examined. — Yunnan: Southwest: Szemao (imale); 

 Laos: Vientiane Province: Vientiane (i female), Tha Ngon (3 

 males, i female) ; Haut-Mekong Province: Ban Houeisai (i female, 



1 unsexed), Nam Khueng (3 males, i female), Lo-tiao (i male) ; 5® 

 Territoire Militaire: Bountai (2 males, 4 females), Phong Saly (i 

 male, i female); Tongking: Laichau Province: Muong Mo (i 

 male), Muong Moun (3 males), Paham (i male, i female), Laichau 

 (i male). 



Remarks. — Since four of the five birds from Vientiane Province 

 were shot in July and are so grayed from wear as to be subspecifically 

 unidentifiable, the extension of oreiim's range so far to the south is 

 based upon a single specimen and requires confirmation.

Pellorneum nipalense vividum La Touche, Bull. Brit. Orn. Club, vol. 42, Oct. 29,

Diagnosis. — Similar to P. r. oreum, but separable in series by 

 having the rufous of the forehead, crown, and nape darker (almost 

 chestnut) ; the brown of the remaining upper parts deeper in tone 

 (about like that of P. r. mandellii) ; the dark centers to the feathers of 

 the uppermost back still more conspicuous ; the under parts somewhat 

 more boldly streaked. 



Range. — The valley of the Red River from the Chinese frontier to 

 its mouths and thence southward along the coast of the Gulf of Tong- 

 king to central Annam, 



Specimens examined. — Tongking: Backan Province: Backan (i 

 male) ; Annam: Thanhhoa Province: Hoixuan (6 males, 2 females, 



2 unsexed) ; Vinh Province: Phuqui (i unsexed) ; Quangtri Prov-
