The propriety of separating the somewhat varied races of this species is questionable, 

 and the possibility of doing so is rendered more difficult from the fact of specimens 

 from British Guiana recently sent us by Mr. H. Whitely being almost exactly like our 

 Central-American examples. The males of these are all of a grassy green hue, and 

 have little of the purplish gloss observable in Ecuadorean, Amazonian, and Bolivian 

 specimens. Colombian specimens, even in the Cauca valley, hardly differ from these 

 latter ones, whereas at Panama the green birds are found. From Western Ecuador we 

 have a specimen shot in the Balzar Mountains to the northward of the Bay of Guayaquil. 

 This is the greenest of our whole series, and must be placed with our Central- American 



birds. 



Eegarding the name the Central-American bird should bear, we are in some little 

 doubt. That the title Certhia spiza of Linnaeus is applicable to one of these races 

 seems unquestionable, and it may well have been given to the Guiana form. The 

 Central-American bird agreeing sufficiently with this may therefore also be called 

 C. spiza. Should the Amazonian and Brazilian bird require nominal distinction, 

 Vieillot's name C. atricapilla is available for it. 



Though we think the Central- American birds to be inseparable amongst themselves 

 and from the Guiana bird, it must be noted that a certain amount of variation can still 

 be traced. The bill in the Guatemala birds is decidedly longer than that of more 

 southern specimens, and the wing is rather longer also. The Panama bird, though of 

 the same colour as the Guatemalan, has the short bill of specimens from South America. 



Chlorophanes spiza in Guatemala is only found in the forest-region of the Atlantic 

 side of the mountains, up to an elevation of about 2000 to 3000 feet. At Choctum
