All the previously known localities for each species are 

 given, but the exact specimens procured by the German 

 South-polar Expedition do not appear to be specially 

 mentioned. 



The Sheathbill of Marion Island is separated as a new 

 species, under the name Chionis marionensis. Dr. Keichenow 

 has never seen it (!), but Dr. Sharpe has stated (Cat, B. xxiv. 

 p. 712) that it is smaller than the form of Kerguelen Island 

 and has a "conspicuously smaller bill." That is quite 

 enough, we suppose, in these days ! 



Four well-drawn plates illustrate scenes of polar bird- 

 life, and there are also many good figures introduced into 

 the letterpress. Dr. Reichcnow promises us an essay upon 

 the oceanic birds of the western hemisphere on another 

 occasion. 



71. Salvadori on a new Vulture. 



[T. Salvadori. Gyps erlanyeri, nov. sp. Bol. Mus. Univers. di Torino, 

 vol. xxiii. no. 576 (25. iii, 08).] 



Count Salvadori is of opinion that two species of Vultures 

 have been confounded under the name Gyps rueppelli — 

 (I) the true G. rueppelli, as figured by Cretzschmar in Riip- 

 pell's Atlas under the name Vulti/r kolbii ; and (2) the bird 

 described and figured by v. Erlanger in the J. f. O. 1904, 

 p. 144, t. 2, as Gyps fulvus rilppelli, which he now proposes 

 to name Gyps erlangeri. The former is generally black, with 

 the apical margins of the wing-feathers semilunar and 

 whitish ; the latter is more decidedly brown, with the wing- 

 margins larger and less neatly limited, and has the under 

 parts uniformly whitish. 



Count Salvadori endeavours to arrange the complicated 

 synonyms of these two nearly allied species under their 

 respective heads, but, as he rightly states, there is much 

 more to be done before this task can be satisfactorily accom- 

 plished. For the area of Gyps rueppelli he gives Western 

 Abyssinia, the Blue Nile, and Khartoum ; for that of 

 G. erlangeri, Erythrsea, Western Abyssinia, and Somaliland.
