as a locality where it is abundant ;* and the European dealers are usually well supplied with 

 skins of the well-known " make" of that colony. Eichard Sehomburgk, as we have already 

 mentioned, met with it in the Eoraima mountains, in the interior of British Guiana at an 

 altitude of about 1000 feet, when engaged in his search for the ripe seeds of the Strychnine 

 (Strychnos toxifera.) Mr. Wallace encountered it on the opposite side of its range, on the Serra de 

 Cobati, near Guia on the Upper Rio Negro. 



The specimens of the Peruvian Cock-of-the-rock (JR. peruviana) that have come before us 

 have been mostly received in collections from Bogota. Whether these were collected in the 

 valley of the Magdelena, or on the opposite watershed, or both, we have no means of ascer- 

 taining. Goudot, whose nesting-experiences of this species in New Granada we have before 

 alluded to, unfortunately does not give the exact locality where he observed it. 



Tschudi speaks of having seen many hundred examples of B. peruana,} in Peru, but he 

 also neglects to mention the precise district in which they occurred. We cannot however be 

 wrong in supposing that it was in the eastern wood region of that country, as Markham mentions 

 having met with " Cocks-of-the-rock" in the provinces of Caravaya, on the upper affluents of 

 the Purus.J Moreover, D'Orbigny obtained examples of this bird in the adjoining wood-region 

 of Bolivia on the eastern slope of the Andes of Yungas and in the mountains east of 

 Cochabamba.§ 



As regards the present species, R. sanguinolenta, we have already stated that we believe it to 

 be strictly confined to the Transandean forests of Ecuador. Cabanis and Heine, who have 

 described what we consider to be the same species, under the name of R. saturata, say that 

 their specimens were stated to have been received from Bolivia. But knowing how little reliance 

 is to be placed on the localities given by dealers, we cannot help thinking there must have been 

 some error on this point. 



Full reference to the synonymy of the three species will be found in Mr. Sclater's Catalogue 

 of American Birds, p. 253. Our figure is taken from one of Fraser's specimens, from Nanegal, 

 now in Mr. Sclater's collection.
