On the Birds of Aden and the Neighbourhood. 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 with 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.]

(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 Otliman and 
Huswah. This plain, with some small rolling sandhills, 
stretches almost as far as A1 Hautah (Lahej), about four miles
