scientific pursuits. Had there not been such an animal as a bird in 

 the whole country, there could not have been less said about the 

 matter. There is, however, a very good topographical index and map 

 appended to this work, which have enabled me to find the situations 

 of several places known as localities whence collections have been sent, 

 but which I could never discover in ordinary Atlases. None of these 

 spots appear to be very distant from Bogota itself, but are situated 

 lower down in the valleys of the streams running into the Magdalena, 

 or upon the upper confluents of the Orinoco, some of which take 

 their rise at no remote distance from the New Grenadian capital. 



The Calliste nigriviridis extends itself along the valleys of both the 

 eastern and western slopes of the Andean range into the republic of 

 Ecuador. On the Pacific side it was procured by M. Bourcier in the 

 valley of Calacali, near Quito ; and specimens have also been trans- 

 mitted to Sir William Jardine, by Professor Jameson, from the same 

 country. These latter were procured on the western slope of the 

 mountain Pichincha, where the bird was found feeding on the berries 

 of various species of Melastoma. On the opposite side of the great 

 range, this bird occurs on the upper Rio Napo, in the province of 

 Quixos, whence specimens have been received by Mr. Gould. 



I have given no figure of this Tanager, but Plate XXXV repre- 

 sents the next following closely allied species Calliste cyanescens, 

 which very nearly resembles the present bird.
