than the type there described. It is probable therefore that the 

 original skin sent us by Arce, but of which the sex was not 

 noted, belongs to a female bird. 



Of the so-called Urubitinga schistacea, which I now propose to 

 place in the genus Leucoj)ternis, I have recently seen and obtained 

 skins which were collected by Hauxwell at Pebas, and by Bart- 

 lett near Cashaboya, on the Rio Ucayali ; in the adjoining dis- 

 trict, on the Rio Javarri, Mr. Bates procured specimens of it. I 

 have also secured a skin which I found in a collection from Bogota 

 which had been forwarded to Mr. Cutter direct from that city. 

 This bird was probably obtained in one of the Andean valleys 

 which stretch away from the cordillera to the eastward. The 

 range of the species seems to be restricted to the basin of the 

 Amazon and its large tributaries. In addition to the localities 

 already mentioned, Mr. Sclater refers to its occurrence in Bolivia. 

 Natterer obtained two examples during his journey — one at Borba 

 on the Rio Madeira, and the other at Barra do Rio Negro. All 

 these places come within the limits of Upper Amazonia ; but we 

 have Prof. SchlegeFs authority for its occurrence near Para, and 

 in Guiana, near Cayenne; a specimen in the Leyden Museum 

 is also stated to have come from Brazil, which term doubtless must 

 be construed in a political rather than in a zoological sense. 



The ten species of this genus (specimens of all of which, except 

 L. melanops, are in our collection) may now be arranged as fol- 

 lows, the synonymy of eight of them being given in the article 

 already referred to: —
