304 THE BIRDS OF MONGOLIA ETC. 



Muni-ul, and Hara-narin-ul mountains. In its voice and flight it almost 

 exactly resembles the preceding species, although, upon a close examination 

 of the two sounds, one can find a slight diff^erence, which, however, it is 

 very difficult to describe. 



E. ohsoleta also keeps in small flocks on the stony parts of plains, 

 especially at the foot of some mountains w^hich abound with rocks and 

 slopes. Contrary to the last species, the present one often visits the deserted 

 Mongolian villages, and pecks about in the dirt. 



I cannot state with certainty whether E, olsoleta stays all the year 

 round in the localities where we found it, or whether it leaves for the 

 winter ; but it appears to me that the former is the most likely, although 

 we did not meet with a single bird during November 1871 from Ala-shan 

 to Kalgan, where we observed them in summer. 



The Hoang-ho or, rather, the Muni-ul mountain- chain forms the 

 northern boundary of the distribution of this species, which most likely does 

 not extend eastwards beyond Ordos, as it has not been seen in China 

 proper. 



161. Uragus sibiricus, Pall. 



Bonaparte^ Monographie des Loxiens^ pis. xxxiv. & xxxv. 



This species came under our observation only in the Guchin-gurb hills 

 north of Dolan-nor, late in March and early in April, in pairs and small 

 flocks, in the bushes overgrown with reeds and long grass. 



162. Pyrrhospiza longirostris, n. sp. (Plate LIV. vi.) 



P. punicem similis^ sed major et rostro longiore. Mas fusco-griseus ; fronte superciliis latissimis^ 

 genis colloque sanguineo-coccineis^ argenteo aspersis ; pectore et uropygio Isetissime roseis, 

 subcaudalibus roseo tinctis. 



Fern, subtus cum fronte sordide albida^ dense fusco striata ; uropygio flavescente.
