SCLATER AND SALVIN ON [Mar. 4, When we consider how little is known of even the higher mammals, and how limited at present is the range of geological inquiry, we must acknowledge that, for some time to come, all generalizations bearing on the question of our origin are premature ; for a vast field for observation still widens out before us, within the boundaries of which we have but lately entered. 6. O n the Birds of Eastern Peru. By P. L. S C L A T E R , M.A., Ph.D., F.R.S., Secretary to the Society, and O S B E RT S A L V I N , M.A., F.Z.S. With Notes on the Habits of the Birds, by E D W A R D BARTLETT. [Received February 7, 1873.] (Plates XXV. & XXVI.) In our first paper on the collections made by Mr. Edward Bartlett*, we have given an account of the principal authorities on the ornithology of Eastern Peru. In that and subsequent communications we have also given lists of the greater part of Mr. Bartlett's collections. Soon after his return home, Mr. Bartlett furnished us with a complete list of the birds he had obtained, based upon our papers, together with valuable notes on the habits of many of the species. This list, however, on account of changes in nomenclature and imperfect determinations, required thorough revision ; and it is only lately that we have been able to devote the necessary time to that purpose. In order to make it more complete we have included in the list, besides some additional species brought home by Mr. Bartlett on his return, the names of the species obtained by Mr. Bates from the Rio Javari, and by Mr. Hauxwell at Pebas and on the Huallaga and Ucayali. Thus the present paper contains a summary of nearly all that is accurately known of the ornithology of the most eastern part of the wood-region of Eastern Peru, from its extreme eastern boundary (the Javari) to the district traversed by Mr. Bartlett on the western bank of the Huallagaf. * Proc. Zool. Soc. 1866, p. 175. t The following is a complete list of the ornithological papers referring to this district:- 1. On a Collection of Birds transmitted by Mr. H. W .
