The late Mr. Cassin, when writing on some birds of Costa Eica ^, stated his sus- 

 picion that Buarremon chrysopogon, of Bonaparte, and Arremon gutturalis, Lafresnaye, 

 referred to one and the same species ; and Salvin, on seeing Lafresnaye's type in the 

 Museum of the Boston* Society of Natural History, at once came to the conclusion that 

 Buarremon gutturalis was the proper title for this Tanager ^. 



The species is a common one in the highlands of Guatemala, being found in the 

 forests of the volcanoes of Agua and Fuego at altitudes varying from 6000 to 8000 or 

 9000 feet, and in Alta Vera Paz near Cohan as low as 4000 feet. Like B. hrunneinucha, 

 its usual resort is near or on the ground, where it searches dead leaves and rubbish for 

 insects. When disturbed it will fly into the upper branches of the forest-trees. 



In the upland forests of Costa Eica and Panama it appears to be equally common ; 

 and it is also found in similar situations in Northern Colombia. 



Salmon's specimens were obtained near Medellin and Eemedios, in the State of 

 Antioquia, at an elevation of about 5000 feet above the sea ^. 



He here found its eggs, which are described as of a very pale greenish blue ^, and 

 thus resemble those of B. hrunneinucha. 



The normal colouring of the throat in this species is a pale yellow ; but specimens 

 occur in which the throat is rich orange. We have several such specimens from the 

 State of Panama. 



The specimen from Coban called B. alhinucha ^^ is a young bird of this species, in 

 which the whole undersurface is slightly tinged with yellow. The young of both 

 B. gutturalis and B. alhinucha are thus coloured ; but the yellow of B. alhinucha is 

 much deeper in tint than in the Coban bird. 



When describing this species under the name Chrysopoga typica, Bonaparte gave its 

 habitat as California, on the faith of a label in the Paris Museum i^. The statement 

 is doubtless erroneous. We know nothing of the species north of Guatemala.
