Tlie birds from Maipures and Perico are intermediate in colour between 

 specimens from Surinam in Mus. H. v. B. and Tring (true mexicana), and specimens 

 from Trinidad (and the eastern littoral of Venezuela ?) (= C. vieilloti) \ they are 

 nevertheless nearer to the former than to the latter. Compared with the Surinam 

 birds, they show the middle of the breast and the abdomen of a purer or deeper 

 sulphur yellow (instead of whitish yellow), the shoulder patch of a purer coerulean 

 blue (not so greenish blue), and the cyanine blue of the throat and sides of the 

 head also deeper. 



La Pricion : (?c? 13. xii. (Andre coll.) These specimens agree fully with those 

 from Maipures and Perico.
