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 Pyrrltula). Iris bright scarlet. Mr. Eyton has given an anatomical description of this bird in the Appendix. DoLICHONYX onYzivonus. Swains. Dolichonyx oryzivorus, Swaina. Faun. Bor. Am. 2. 278. Emberiza oryzivorus, Linn. This one specimen only was seen at James Island, in the Galapagos Archipelago, 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 grounos, 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. 1. XAtsTHORNUS CHRYSOPTERUS. G. R. Gray.

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, accordmg 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. |
