On the Birds of Aden and the Neiyhbourhood. 11 



Another season^s work on the part of Mr. Wayne will 

 doubtless throw more light on all these points. Meanwhile, 

 ornithologists may well rest satisfied Avith the knowledge thus 

 far obtained. — The Auk, vol. ii. pp. 346-8. 



[Specimens of Swainson's Warbler are very rare in Eu- 

 ropean collections. In the British Museum the only example 

 until lately has been a single female^ obtained by Mr. Edward 

 Newton in Jamaica (see A. Newton, P. Z. S. 1879, p. 552, 

 and Sharpe, Cat. Birds, x. p. 233) . To this has been lately 

 added one of the fine adult males procured by Mr. Wayne, 

 as above recorded, which was kindly sent to Sclater by 

 Dr. Coues, and transferred by him to the British Museum 

 in the name of the latter gentleman. — Edd.] 



IV. — On the Birds of Aden and the Neighbourhood. By Major

(Plate II.) 



The peninsula of Aden (Plate II.) is situated in lat. 12° 47' N. 

 and long. 44° 59' E., and is, roughly speaking, five miles in 

 its greatest length and three miles in breadth. The centre 

 of the peninsula is formed by the Shum-shum range of 

 mountains, the highest peak of which rises to 1760 feet. 

 From this range spurs run down to the sea, with deep ravines 

 between them, ending at the sea in sandy beaches. On the 

 north side an elevated plateau lies between the cantonment 

 of Aden and the foot of the range, this plateau being deeply 

 cut by watercourses. The peninsula is joined to the main- 

 land by a low, sandy, and barren isthmus, about two miles 

 long by three quarters of a mile broad. The general cha- 

 racter of the country inland is a sandy plain, with salsola 

 (near the sea), babool, and caper bushes, a little cultivation 

 being found in the neighbourhood of Shaikh Othman and 

 Huswah, This plain, with some small rolling sandhills, 

 stretches almost as far as Al Hautah (Lahej), about four miles
