Upper part of the head, body, wings and tail, olivaceous brown ; the throat, and 
beneath the body, cinereous ; the bill and feet pale brown. 
Habitat, Galapagos Archipelago. (Chatham and James Island). 
I believe my specimens, which include both sexes, were procured from Chat- 
ham and James Islands ; it is certainly found at the latter.

This is not a very uncommon bird in Central Chile : the farmers complain 
that it is very destructive to the buds of fruit trees. It is quiet and solitary, and 
haunts hedge-rows or bushes ; its manners are similar to those of our bullfinch, 
( Loxia Pyrrhula). Iris bright scarlet. Mr. Eyton has given an anatomical 
description of this bird in the Appendix.

This one specimen only was seen at James Island, in the Galapagos Ar- 
chipelago, during the beginning of October. It is remarkable that a bird 
migrating, according to Richardson, as far as 54° N. in North America, and 
generally inhabiting marshy grounds, should be found on these dry rocky islands 
under the equator. Mr. Gray and myself carefully compared this specimen 
with one from North America, and we could not perceive the slightest difference.

Oriolus cayennensis, Linn. Syst. 1. 168 ? 
Agelaius chrysopterus, Vieill. 
Psarocolius chrysopterus, Wagl Syst. Av. p. 
This bird generally frequents marshy grounds. I procured specimens from 
La Plata and from Chile ; in the latter country it extends at least as far north 
as the valley of Copiapo, in 27° 20' : on the eastern plains it does not range, 
according to Azara, north of 28°. It builds in reeds. Molina says it is called 
by the Indians Thili, or Chile — hence he derives the name of the country.
