18 Lord Walden on the Sun-birds 



CicoNiA ALBA, Bechst. White Stork, Arab. " Najeb.'* 

 I did not see this bird myself; but Captain Palmer, U.E., saw 

 a large flight of birds, which I have no doubt were of this species, 

 in Wady Feiran, March 5th. Mr. E. H. Palmer also saw a 

 flight. " Najeh " means literally, " a white shecp.'^ 



*Egretta GARZETTA, Linn. Little Egret. 

 Shore of the Gulf of Akabah. 



Phalacrocorax. carbo (L.). Common Cormorant. 

 Very common in the bay near Tor, and along the coast of the 

 Red Sea. 



Larus gelastes, Licht. Slender-billed Gull. 

 This Gull is common in the bay at Tor. 



Chroicocephalus ridibundus (L.). Black-headed Gull. 



Chroicocephalus melanocephalus (Natterer). 

 I was able, through my glass, to distinguish both this and the 

 preceding species, which were both common in the bay at Tor. 



IL — On the Sun-birds of the Indian and Australian Regions'^. 

 By Arthur Viscount Walden, P.Z.S. &c. 



(Plate L) 



All those Sun-birds which are not found in the Ethiopian 

 region form the subject-matter of this paper. The geographical 

 range of the group extends, on the mainland of Asia, from the 

 mouth of the Indus, in the west, to the shores of the Chinese 

 Sea in the east. It includes, besides Ceylon, nearly all, if not all, 

 the islands of the Indo-Malayan and Austro- Malayan subregions. 

 Its most northern and north-western limit is reached in the 

 neighbourhood of Kotegurgh, on the Sutlej, and its most south- 



* The term "Indian Region" is here used in a purely geographical 

 sense. As a zoogeogTaphical expression, I find difficulty in recognizing its 

 value ; for the avifauna of continental Asia, south of the middle range 

 of the Himalaya and of its eastern extensions, may be roughly said to 

 consist of two distinct groups of birds — the one inhabitants of the 

 mountains and their slopes, the other inhabitants of the plains. The first, 

 in whatever part of India proper they occur, are allied to Indo-Malayan 

 forms ; the last are closely connected with African species or genera.
