THE BIRDS OF MONGOLIA ETC. 



204. Caccabis MAGNA, n. sp. 



C. cJiukar simillima^ sed major et supra pallidior ; loris nigris^ vitta superciliari nigra non interrupta ; 

 circulo gulari rufo, margine interno nigricante. 



The following are the more exact distinctions of the present species 

 from the closely allied C, chuhar : — Qa^ larger size ; (6) lores and superciliary 

 stripes under a white line are black, as in C. saooatilis ; (c) the collar of the 

 neck is double, on the inside it is blackish or black, on the outside reddish 

 brown and almost of the colour of the ear-coverts ; under the throat the 

 collar is indistinctly marked; (t?) the black stripes on the flanks are as 

 narrow as they are on C. saxatilis^ but the distance between them is as large 

 as it is in C. chuhar ; (e) the upper parts of the body are paler than they are 

 in Chinese specimens of C, chuhar ; (/) comparatively, the voice also seems 

 to be difi^erent.

We first obtained this bird in the most desolate parts of South 

 Koko-nor mountains ; and later on we met with it also in Northern Tibet 

 and the Tsaidam plains. In its habits it does not differ from C. chuhar^ and 

 keeps usually in small companies (probably families) on the rocky mountains 

 and in their neighbourhood. 



When taking to wing it utters a peculiar hollow note, something like 

 '' cuta-cuta^'' which we never noticed in C. chuhar i and the present species 

 seems to be more silent than the preceding one.
