Syrrhapfes tibetanus^ Gould, P. Z. S. 1850, p. 92 ; Hume and 

 Marshall, Game Birds of India, i. p. 43, pi. (1879); 

 Ogilvie-Grant, Cat. Birds Brit. Mus. xxii. p. 5 (1893). 



Adult Male — Differs from S. pa7'adoxHS in having the abdo- 

 men white, with no black patch; the black vermiculations, or nar- 

 row wavy markings, on the back of the neck and interscapular 

 region, are very fine, and gradually become obsolete on the 

 wing-coverts and scapulars. Total length, 16 inches; wing, 

 9'8 ; tail, 7*9 ; tarsus, i. 



Adult Female. — Similar to the male, but having the vermicu-

 tarsus, I. 



Nestling. — Closely resembles that oi S, paradoxus.
