considerable number of specimens of birds, wbich are now in the 

 British Museum and in the Derby Collection at Liverpool. Most of 

 the pecuhar Bohvian species, therefore (such as Buthraupis montana, 

 Compsocoma Jlavinucha, Diuca speculifera, Poospiza luteocephala, 

 &c.)j are still scarce in collections. Other birds, however, first 

 discovered by M. d'Orbigny in Bolivia, have since been found in great 

 abundance farther northwards, in Eastern Peru and New Grenada, 

 and in fact many of the South American species seem to have a very 

 extensive range from north to south in this direction. Such is the 

 case with the present Tanager, and, as I have already had occasion 

 to remark, vdth Calliste guttata, C. gyroloides, and C. boliviana. 



The Blue-necked Tanager was found by d'Orbigny in company 

 with Callistae yeni and schranki in the forests inhabited by the 

 Yuracares Indians, who call it " Pisuta." Like the two latter species, 

 he tells us it goes in small troops, constantly moving about among the 

 summits of the forest-trees and palms. Dr. Tschudi met with this 

 bird in the hot wood-region of Eastern Peru, and the specimens 

 upon which Swainson founded his name cceruleocephala were, I 

 beheve, obtained by one of Sir W. Hooker's Botanical Collectors in 

 the same country. Farther northwards we find it occurring on the 

 Rio Napo in the Equatorian province of Quixos, and by no means 

 uncommon in collections brought from Bogota. 



The only near aUy of the present bird is the last species, C. nigri- 

 cincta, to which it presents some resemblance in the arrangement of 

 the colours, but, as will be seen by the figures, the two birds are not 

 sufiiciently alike to render them liable to be confounded together.
