New Birds from Tibet. — We are glad to find that some 

 additional knowledge of the Tibetan Avifauna is likely to be 

 one of the results of Sir Frank Younghusband's march 

 to Lhasa. Mr. Dresser has already described before the 

 Zoological Society three new and distinct species of Passerine 

 birds, of which specimens were obtained by Col. Waddell, 

 C.B., in the Tsang-po Valley, near the Chuksan Ferry, at 

 an elevation of about 12,100 feet above the sea-level. These 

 were named Babax waddelli, Garrulax tibetanus, and Lanius 

 lama. Besides these, we understand that a good collection 

 of birds was made by Captain Walton of the Indian Medical 

 Service, who accompanied the expedition as Naturalist. This 

 collection was left at Calcutta, but is to be sent home to 

 South Kensington for determination, while the question 

 of its ultimate disposition, we are informed, is not yet 

 settled. 



The Nehrkorn Collection of Birds' -Eggs. — As we learn 

 from the Report of the 54th Anniversary Meeting of the 

 "Deutsche Ornithologische Gesellschaf t " (J. f. O. 1905, 

 p. 255), Herr Nehrkorn has presented Ids famous Collection 

 of Birds'-Fggs to the Zoological Museum of Berlin. As is 

 well known to every ornithologist who has visited the city 

 of Brunswick, and to many others, Herr Nehrkorn was the 

 owner of one of the largest and best collections of birds'-eggs 

 in existence, and its acquisition has enormously increased 

 the extent of the series at Berlin. A catalogue of the 

 Nehrkorn Collection was published in 1899 (see ' Ibis/ 1899, 

 p. 462). It is now proposed to prepare a new edition of 

 this catalogue.
