ARKIV FÖR ZOOLOGI. BAND 5. N:o 9. Notes 011 Bircls collected by Mr. Otto Bamberg in Southern Transbaicalia and Northern Mongolia. By EINAR LÖNNBERG. With 9 Figures in the text. Read january 13th 1909. Last year Mr. Otto Bamberg of Weimar made a col-lecting expedition chiefly to Northern Mongolia and the ad-joining parts of TransbaicaHa. During this expedition, I regret to say, Mr. Bamberg was badly hurt.by falHng from his horse. This accident unfortunately prevented him from making the collection as great as it otherwise undoubtedly would ha ve been. The birds which have been entrusted to the present author för examination and determination are, however, of great interest as they have been collected during the breeding season in that little kno^vn, and partly from an ornithological point of view unknown country. In fact, Mr. Bamberg maintains that .practically every species represented in the collection* really breeds in the neigh-bourhood where it has been collected. This adds, of course, a great deal to the scientific value of the collection which thus gives an idea of the ornis of Northern Mongolia and it proves also that this country is inhabited by some indige-nous subspecies as well. ^ The greater part of the same now belongs to the Xatural History Museum of Stockhohn.
