BIRDS.

(Plate 4.) 



From the summit of lloraima Mr. McConnell brought several specimens of a 

 Zonotrichia quite distinct from the ordinary Z. pileata which is found over the greater 

 part of Central and South America. It is a larger and darker bird, much greyer, 

 and with the rump and flanks dark grey instead of brown. I propose to call it after 

 Mr. McConnell, who has done so much for the collections of the British Museum.
