196 Mr. O. Salvin on Birds 



Camacusa. — A hamlet on the south hank of the Mazaruni 

 River, in lat. 6^^ N., long. 60° W. 



Kukenam. — One of the mountains of the Roraima series, 

 of similar shape and elevation. 



Merum^ Mountains. — A group of mountains of about 

 2000 feet elevation, lying to the N.E. of Roraima, in a bend 

 of the Mazaruni River, which rises on their southern slope. 



Roraima. — A singular mountain, which reaches an eleva- 

 tion of upwards of 8000 feet, the upper 1500 feet or so 

 consisting of perpendicular cliff rising out of a forest-clad 

 talus of a similar height. The country surrounding this 

 mountain consists of undulating savanas with patches of 

 forest. Until quite recently the summit of Roraima was 

 supposed to be inaccessible, but in the early part of February 

 last Mr. Everard F. im Thurm reached the top ; the full 

 details of his journey have not yet reached this country. 



Yw'uani River. — Rises in Kukenam and flows south-west- 

 wards, joining the Caroni and ultimately the Orinoco. 



At the conclusion of this list of Birds I propose to give a 

 summary of its contents, and some remarks on the general 

 relationship of the avifauna of the district to that of the 

 surrounding regions. 



The only authority on the birds of British Guiana is 

 Richard Schomburgk, who explored the country in 1840-44, 

 and an accouut of whose collections were published in his 

 ' Reisen in Britisch-Guiana ' in 1848. The birds, which were 

 determined by Prof. Cabanis, numbered 418 species, many of 

 which were then described for the first time. I have, in the 

 following catalogue of Mr. Whitely's birds, in all cases 

 referred to this work ; and in order to render this list of 

 British Guianan birds more complete, I have added the 

 names of the species mentioned by Schomburgk, but not 

 contained in Mr. Whitely^s series. These are distinguished 

 by an asterisk prefixed to them.
