(Plate LXXII.) 



The birds to which I invite attention were collected during excur- 

 sions to the island of Socotra and to Southern Arabia in April last. 

 In the former place Dr. Riebeck was accompanied by the celebrated 

 African traveller Dr. Schweinfurth. 



The Socotran collection contains 42 specimens, referable to 20 

 species : — 



Passeres 10 species. 



Picarise 1 



Herodio cs 1 



Anseres 1 



Columbse 3 



Limicolse 3 



Gavige , • I 



In it there are 7 species not obtained by Prof. Balfour, including 

 a fine novelty. These species are : — 



1. Bhyncliostruthus riebecM, n. sp. 



2. (Ena capensis. 



3. Ardea purpurea. 



4. Totanus glareola. 



5. Fuligula nyroca. 



G. Phalacrocorcix lucidus. 

 7 . Gallinula chloropus. 



Dr. Schweinfurth writes me the following notes on the Socotran 

 localities mentioned by Dr. Riebeck on his labels : — 



" In Socotra we were only on the north coast; and besides the 

 immediate environs of Golonsir and a short excursion made by 

 Dr. Riebeck to the west of Tamarida, we explored only the country 

 about this latter place and. the central granite mountains. 



" Our longest stay we made in a mountain-valley ' Wadi Dilal ' 

 (or Digal), and at a' place called ' Keregnigi,' which abounds with 

 boulders of grey granite and caverns. 



" Gebel Firi is the name of one of the numerous granitic peaks of 

 the Haygier. 



" The uppermost part of Wadi Dilal is named Rischen. The 

 country to the south of this place (above 900 metres) is situated on 

 the northern slope of the central granitic mountains to the S.E. of 

 Tamarida. 



" Dr. Riebeck collected many birds in the plains to the east and 

 S.E. of Tamarida, upon the rivulet conducting to the Belled el Schech, 

 and others on the rivulet whicli opens near Tamarida."
