166 On a new Perdlcine bird from Tibet [No. % 



the spur on the legs. But it is probably absent or but slightly 

 developed. 



The other members have been sufficiently described in the generic 

 character. 



The colours are as follows : 



Bill and legs, horn green. Orbital skin, reddish. Above trans- 

 versely marked with black, rufous and chesnut, in frequent bars, the 

 black being more developed on the wings, and the chesnut on the 

 flanks, where indeed the black nearly disappears, while on the belly, 

 it is so much developed as to constitute the main and almost only 

 colour. Neck, above and laterally, and all the lateral tail feathers, 

 full unmarked chesnut : cheeks, throat and breast, luteous or albes- 

 cent buff. A black zone round the throat from the cap, and a black 

 patch below the eye. 

 The size is as follows : 



Tip of bill to tip of tail, 1.1.0 



Expanse of wings, 1.6.0 



A closed wing, 0.6.i 



Bill to gape, 0.0.| 



Bill to brow, . ...... O.O.f 



Tail, 0A0 



Tarse, 0.1.* 



Central toe and nail, 0.1. \ 



Weight 1 ft. 

 In conclusion I may remark that the bird has much of the cha- 

 racter of Caccabis, whilst in colours it resembles greatly the grey 

 partridge of India, without however, losing certain Caccabine traits 

 which the expert will at once detect on turning to the accompanying 

 beautiful drawing, the work of my native artist.*
