(^arnagnan and San Fernando de Apure. I was able to 

 procure many specimens, dead and alive. Three live birds, 

 2 (^ and 1 $ , are in mj aviaries, where I hope to breed 

 them and study their eggs and young ones, which were 

 not obtainable in Venezuela while I was collecting in that 

 country. 



This species is very different to Brotogeris devillei (Gray), 

 collected by Mr. G. K. Cherrie in the Orinoco region, and to 

 B. chri/sopterus (L.), found in other parts of Venezuela. 

 Its nearest relatives seem to be B. pyrrliopterns (Lath.), 

 found on the Pacific coast of Ecuador and Peru, and 

 B. jugidaiis (Mull.), from Southern Mexico, Central 

 America, and Colombia; but the new species differs 

 entirely in the colouring o£ the head, the under coverts 

 of the wing, etc. "1 



Mr. H. KlEKE SwANN exhibited, on behalf of Dr. Casey 

 Wood, a fossil egg, supposed to be that of the Tropic-Bird 

 i^Phaetlion fiavirostris), excavated February 1915, from a 

 quarry at Tuckerstown, Bermuda, from the coral limestone 

 or. Paget formation — a post-glacial deposit that covers most 

 of the islands. It varies in thickness from a few inches 

 to several hundred feet. This specimen was found about 

 15 feet below the surface. 



He also exhibited a number of photographs obtained by 

 Dr. Casey Wood, comprising : —
