 {Zeledon ^), San Carlos [Boucard ^). 



The first specimen of this remarkable bird was sent us by our collector Arce in 1864 ^, 

 and formed the type of the description and figure in the ' Proceedings of the Zoological 

 Society ' for that year. It was shot near Tucurriqui, a hamlet in a valley on the Atlantic 

 slope of the mountains of Costa Eica. Another specimen, a male, was obtained by Mr. 

 H. E. Holland in the following year near Greytown in Nicaragua ^. Others have since 

 been obtained by Mr. Zeledon and M. Boucard ; the last-named traveller shot an adult 

 female at San Carlos, which is the only female we have seen, and owing to his 

 kindness is that figured on our Plate, A young male in the Museum of the University 

 of Cambridge resembles the adult, but has the first (unmoulted) primary in each wing 

 like that of the female. 



All the places where this bird has hitherto been found are on the Atlantic slope of 

 the Cdsta-B.ican Cordillera, where a dense tropical forest prevails.

Hob. Costa Rica, Pirris [Zeledon ^ ^ ^). 



The only specimens hitherto obtained of this second species of Carpodectes all come 

 from the neighbourhood of Pirris, on the western slope of the mountains of Costa Rica. 

 They were all collected by Mr. Zeledon, to whom we are indebted for a male and 

 a female skin, which are now in the British Museum. Mr. Zeledon says " the bird 

 caimot be called common, and it was by mere accident that I came across a tree with 

 ripe fruit for which it shows much partiality, and there I stationed a man to watch and 

 shoot the birds as they arrived to feed. I have not heard its song, nor has anyone 

 else that I know of. The call-note resembles very much that of Tityra persoiiata."

Four species constitute the genus Chasmorhynchus, all of them remarkably distinct 

 from one another. The ranges of these species spread over a considerable portion of
