Genus DENDROICA Gray. 



Dendroica Gray, List. Gen. B. App. III. p. 8 (1842). 



Tlie genus Itemh-okn is largely represented in North and Bliddlc America, the 

 W'est Indies and the most northern part of South America, while the other parts of 

 South America are greatly frecinented by migrants from North America, bnt have 

 no resident forms of the genus. The Galapagos Islands are inhabited by one 

 species, which has no very near ally in South America, but rather in the West 

 Indies. 



1. Dendroica aureola (Gould). 



Sylricola aureola Gould, Zool. Beagle, III, Birds p. 86. PI. XXVUI. (1841).

We have this species from the following islands : — Culpepper, Wenmau, 

 Abingdon, Bindloe, Tower, Albemarle, Narborough, James, Jervis, Duncan, Inde- 

 fatigable, Chatham, Charles, Gardner and Hood. 



The affinity to P. petechia of Jamaica is remarkable. D. cureola differs from 

 the latter in having a more intensely orange-rufous, much darker pileum, in being 

 generally slightly darker on the back, and in having the wing generally one or two 

 millimetres longer. Specimens from Gorgona Island, on the coast of Colombia, 

 and ( 'ocos Island are quite like those from the Galapagos Islands. The species is 

 also said to occur at Guayaquil (Baur & Adams) and in Peru (Solzmann & 

 Raimondi), but we have not seen continental specimens. 



D. rufoinleuta of Curasao, Bonaire and Aruba has the crown still deojier, of a
