interior to any extent. He also published an account of 

 Ids travels, ' Reisen in Nubien, Kordofan und petraisclien 

 Arabien' (Frank£urt-a.-M. 1829), in addition to his well- 

 known zoological works. 



Turning now to Aden and its hinterland, we find that 

 Col. J. W. Yerbury, M.B.O.U., was the first to publish 

 an account of the birds of Aden. This appeared in ' The 

 Ibis' for 1886, and 76 species were mentioned, but only 

 a small proportion of these were authoritatively identified 

 by Dr. Bowdler Sharpe. Farther lists of Aden birds have 

 been made by Lieut. H. E. Barnes, INIr. R. Hawker, and 

 by Ool. Yerbury himself, all of which appeared in ' The 

 Ibis.' In 1900 Mr. Ogilvie-Grant published a paper on 

 the birds collected by Mr. A. Blayney Percival and Mr. W. 

 Dodson in the hinterland of Aden. The expedition was 

 proposed to the authorities of the Natural History Museuni 

 by General O'AIoore Creagh, V.C., the Governor of Aden 

 at that time, and the necessary funds were supplied partly 

 by the Royal Society and partly by the Hon. Walter (now 

 Lord) Rothschild. Considerable collections were made in 

 the Haushabi country north of Lahej, and in the Abian 

 country to the east of Aden. Mr, Ogilvie-Grant, by incor- 

 porating the results of Col. Yerbury's and Messrs. Barnes 

 and Hawker's previous Avork, was able to give a list of 193 

 birds, forty-scveu of which were previously not known from 

 Arabia. 



Mr. Percival was assisted by Mr. G. W. Bury, whom he 

 met at Aden at this time, and the latter subsequently sent 

 a valuable collection of birds, collected chiefly in the Amiri 

 district, to the Museum ; these unfortunately have never 

 been listed, but notice of several of the species in this col- 

 lection will be found in the present paper. 



Mr. Bury also made some further collections when attached 

 to an Austrian Expedition which visited southern Arabia for 

 archaeological investigations. An account of this collection 

 was published by Drs. von Lorenz and Hellmayr, who 

 found a number of new species among them. Since tliat 

 date but little work has been done in Arabian ornithology.
