THE BIRDS OF MONGOLIA ETC. 169 



43. Calamodyta orientalis, Temm. & Schleg. CamishevJca vostochnaya. 



Calamodyta orient alis, Temm. & ScUeg. Faun. Jap. pi. xx. 



This eastern form of the European C. turdoides, Meyer, differing from 

 the latter only by its smaller size, has been obtained by us in the Hoang-ho 

 valley and the Southern Ala-shan, on a small marsh called Bajan-Bulik. At 

 this place a small spot covered with reeds was sufficient to give a 

 home to this little bird in the middle of a frightful desert. By its voice and 

 habits it does not differ at all from the European species. It is common in 

 Ussuri country, especially in the marshy plains east and south of Lake 

 Honka. In spring it arrives in these localities early in May ; and from that 

 time until the end of the summer its song can be heard daily. It breeds in 

 the reeds and thick bushes near the water. The young ones leave the nest 

 about the end of June. 



44. Arundinax aedon, Pall. CamishevJca solovey. 



Only once, in the middle of August 1873, did we come across a 

 specimen, which was lying dead in Gobi, where it evidently died from want 

 of food during migration, as, on opening the stomach, it proved to be quite 

 empty. In Ussuri country it is tolerably common, and inhabits the thick 

 bushes on the shores of rivers. 



45. DUMETICOLA AFFINIS, HodgS. 



Was procured by us in Kan-su only, where it principally breeds on 

 grassy plains of the alpine region. The voice is tolerably loud. A male 

 obtained by us ahve measures— length 5''-2, wing T 25, tail 2''-I, tarsus 0''-74, 

 culmen (black, with the base of the lower mandible yellow^; 0'' 38, 

 gape 0'''57.
