XVIII. — A List of the Birds obtained by Mr. Henry Whitely 

 in British Guiana. By Osbert Salvin^ M.A.., F.R.S., 



&c. 



The following list of Birds is based on a series of collections 

 made by Mr. Henry Whitely in British Guiana during a 

 period of five years (1879-84). Mr. Whitely's travels ex- 

 tended over a considerable extent of country. In his last 

 expedition he penetrated into the mountainous region of 

 Boraima, and ascended to an elevation of upwards of 7000 feet 

 on the slopes of that mountain. 



The first portion of his stay Mr. Whitely passed at Bartica 

 Grove Mission, situated on the Essequibo River, but little 

 above the sea-level. He then made an expedition to the 

 Mazaruni River, passing some time at a place called 

 Camacusa, and visiting the Merume Mountains, which lie on 

 the south bank of that river. His next expeditions were into 

 the Roraima district, which he explored on two occasions. 

 During the last of these he ascended to the foot of the clifiB 

 which form so remarkable a feature of the mountain of 

 Roraima. This last expedition was fully described by Mr. 

 Whitely himself in a paper published in the ' Proceedings of 

 the Royal Geographical Society^ (vol. vi. p. 452) in August 

 last ; a map of the district accompanying this paper shows 

 Mr. Whitely^s route and the position of most of the localities 

 mentioned in the following list : — 



Atapurau River. — A stream rising in Mount Eleutewer, 

 and flowing into the Carimang River, an affluent of the 

 Mazaruni River. 



Bartica Grove. — A station on the Essequibo River, near its 

 mouth, and almost at the sea-level.
