Results uf a Visit to South Guyana. 153 



on a granitic hill on the right hand of the stream, which 

 measures here 43^ m. in breadth, and is bordered by 

 elegant assahy-palms, tabocas (bamboo), and anhingas 

 {Montrichardia) , the favourite food of the Hoatzin. 



In this village we took up our headquarters for a fortnight. 

 Numerous trips were made on every side. We visited alike 

 the forests and " capoairas " (old plantations) behind the 

 village, the savannas beginning some miles distant on the 

 right and left hand of the stream, and the forests on the 

 river above and below. To ornithology principal attention 

 was paid by the zoologists of our small expedition. I think 

 that my readers will agree with me that a chronological order 

 will perhaps be the best way to give a summary idea of our 

 work and results in Counany. At the same time it may be 

 of advantage to compare the features of the ornis of South 

 Guyana with those of the ornis of Para and its neigh- 

 bourhood. 



On the 12th October (the day of our arrival), naturally 

 enough, scientific work could not begin at once. But we 

 obtained during an afternoon walk along the river-border 

 specimens of Tachycineta albiventris and of a Heron [Ardea 

 virescens), the former usually seen sitting on the posts and 

 trees in the water, the latter occupied in the mud between 

 the boats in the harbour. 



The next morning we visited the forest between the main 

 river and its tributary, the Igarape de HoUauda. I heard 

 and observed different Pipridae, called ''Araparu,'^ as in 

 Para, especially Chiromachceris gutturosa, several small 

 Thamnophiliy and a Thrush, to judge by its song, the same 

 species as in Pard,, the common "Caranu^^^ {Turdus albi- 

 ventris). Several small flights of blue Araras were pursued 

 without result; they always had the opportunity of dis- 

 covering us before we could see them on some of the highest 

 trees, where they were evidently occupied on the fruits. 

 From a companion I got a nice specimen of Harpagus biden- 

 tatus, three of Columba speciosa (" Trocal "), and two of the 

 splendid Galbula viridis, the first I had seen of this species. 

 From another of our company, who returned from a walk
