1867.] THE BIRDS OF THE LOWER AMAZONS. 66? 



was hitherto unknown, that this catalogue has been prepared. Mr. 

 "Wallace has rendered it more valuable by adding notes oi\ the habits 

 and range of certain species, which have his initials affixed to them. 



The principal localities wherein the present collection was formed 

 were : — 



1. Mexiana. An island situated in the main stream of the Ama- 

 zons, between the great Island of Marajo and the northern shore. 

 Mr. Wallace has given an account of his sojourn in this island in his 

 ' Travels,' p. 86, where he speaks of it as follows : — 



" The Island of Mexiana is about twenty-five miles long by twelve 

 broad, of a regular oval shape, and is situated exactly on the Equator. 

 It is quite flat, and is all campo, or open ground, but dotted with 

 scattered trees and bushes, and with a little forest at the water's 

 edge. It is celebrated for its birds, alligators, and oneas, and is 

 used as a cattle estate by the proprietor." 



2. Island of Marajo. A few specimens were collected at Jungcal, 

 on the northern side of this island (see 'Travels,' p. 107). 



3. Para. The species marked "Para" were all collected within 

 ten miles of the city. The forest commences within two miles of the 

 town. The whole aspect of the country is fully described in the 

 second chapter of Mr. Wallace's interesting narrative. 



4. Rio Tocantins. The species marked thus were collected be- 

 tween the mouth of the river and the first falls, during the excursion 

 spoken of in Mr. Wallace's ' Travels,' Chap. III. Some interesting 

 remarks on the same subject will also be found in Mr. Bates's well- 

 known ' Naturalist on the Amazons,' Chap. IV. 



5. Rio Capim. This is a small river issuing into the Rio Para, 

 near the city of Para. Mr. Wallace gives an account of his excur- 

 sion up this river in Chap. V. of his 'Travels.' 



P. Rio Negro. A full account of Mr. Wallace's journey on this 

 river and its affluents will be found in Chap. VII. and four following 

 chapters of his narrative. It is much to be regretted that the species 

 from this district recorded in the present list form but a very small 

 portion of the number actually collected — the series reserved by 

 Mr. Wallace for his own use having been lost in the manner already 

 mentioned, and that transmitted to England dispersed without any 

 record having been kept of it. 



Besides the specimens obtained at these localities, a few others 

 were procured at various points of the main stream on the voyage 

 up to Barra, chiefly at Moutalegre and Santarem. 



The following list gives the names of all the species remaining in 

 Mr. Wallace's hands from the above-mentioned localities. A few 

 well-known species, identifiable without any chance of error from 

 Mr. Wallace's notes, have been added to it — and a few others, of 

 which examples collected by Mr. Wallace are in Sclater's collection 

 or in the British Museum. 



The nomenclature adopted for the Passeres, Picarise, and Psittaci 

 is that of Sclater's ' American Catalogue,' unless the contrary is 

 stated. The species described as new are three in number, namely 

 Hylophilus rubrifrons, Hylophilus semicinereus, and Heteropelma
