506 Mr. O. Salvin o/i Birds 



The ornithology of Peru has been recently examined 

 with great care, and the results given in M. Taczanowski's 

 ' Ornithologie du Perou/ We thus find 307 of our Guiana 

 birds also meutioned as inhabitants of Peru_, and of these 44 

 are also found in North America. This leaves 263 of more or 

 less restricted range, or about 46i per cent, of the Guiana 

 total less the widely ranging species. and migrants. This 

 number is largely due to the fact that the Peruvian list 

 contains a great number of birds belonging strictly to the 

 Amazons valley. 



There seems to be no species peculiar to Peru and Guiana 

 to the exclusion of the Amazons valley or the Andes of 

 Ecuador or Colombia. But some of the endemic Guiana 

 species find their near relations in these Andean countries. 



Taking Colombia, Ecuador, and Peru together, with a view 

 to ascertaining what relation there exists between Guiana 

 and their more mountainous parts, we find that the following- 

 species are found in both countries, to the exclusion of the 

 lower parts of the Amazons valley: — Setophaga verticalis, 

 Calliste nigricincta, Pyranga ardens, Zunotrichia pileata, Och- 

 thoeca setopliagoides, Contopus ardesiacus, Colomba albilineata. 



And the following genera are represented in both districts 

 by allied species : — Tardus, Basileuterus , Diglossa, Chloro- 

 phonia, Buarremon, Catamenia, Piprites, Pipreola, Heliodoxa, 

 Petasophora, the species of neither country being found in 

 the intermediate lowlands.
