490 MESSRS. SCLATER AND SALVIN ON [June 3, 



to the author, were given by Sclater in a paper read before the Society 

 in 1855, and in two supplementary communications on the same 

 subject l . 



An account of the Trochilida? of the vicinity of Bogota, and of the 

 localities in which they are obtained, has also been given by M. L. 

 de Geoffroy, Secretary to the French Legation at Bogota, in a paper 

 published in Uricoechea's ' Contribuciones de Colombia alas Cien- 

 cias y a las Artes' 2 . 



Since Sclater's papers were published, examples of many additional 

 species have been received in "Bogota" collections; and a complete 

 list of "Bogota" birdskins would embrace probably 700 species, in- 

 stead of 510 given in Sclater's papers. Unfortunately, however, 

 no record has ever been made of the exact localities whence these 

 skins are obtained ; and itseems certain that " Bogota" collections em- 

 brace examples of species peculiar to the valleys on the east side of 

 the Andean range (i. e. from the watershed of the Orinoco), as well 

 as of species from the valleys on the west side and from the elevated 

 districts surrounding Bogota itself. 



Besides "Bogota skins" and their literature, we have, so far as we 

 know, putting aside occasional notices of individual species, only 

 three authorities on the birds of Colombia to refer to. These 

 are: — 



1. Mr. Cassin's Catalogue of the birds collected during the U.S. 

 Survey of the Isthmus of Darien, published in 1801 3 . Mr. Cassin 

 enumerated 144 species in this memoir, some of the rarities of which, 

 as hereafter noticed, recur in the present collection from the neigh- 

 bouring State of Antioquia. 



2. Mr. Wyatt's articles on the birds obtained by him during his 

 expedition to the Andes of Ocana in 1870 4 . Mr Wyatt enumerated 

 210 species as met with by him in this district, some of the more 

 remarkable of which occur also in the present collection.
