 Trochilus milleri Bourc, P. Z. S. 1847. p. 43. 

 Agyrtria milleri Berlepsch & Hartert, p. 83. 



The distribution along- the Orinoco seems to be about the same as 

 with alhivcntris but it is much less common. 



Agyrtria chionopectus chionopectus (Gould). 

 Thaumantias chionopectus Gould, Monogr. Trochili. V: (1859) : pi. 293 



(Trinidad); Stone, Proc. Ac. Nat. Sci. Phil. 1913: p. 201 



(Guinipa Village; Pedernales).

 mouth of the Caura and beyond by the allied race zvhitelyi. 



Agyrtria chionopectus whitelyi (Boucard). 



Uranomitra whitelyi Boucard, The Humming Bird, III. 1893. p. 8. 

 Agyrtria chionopectus whitelyi Berlepsch & Hartert, p. 84. 



This species was reported from the Caura River by Berlepsch 

 and Hartert, having been collected by both Andre and Klages. In 

 May, 1907, the writer found it abundant along the San Feliz River 

 near its union with the Cuchivero River. Either this or typical chion- 

 opectus will be very likely found in the Orinoco Delta.

 Saucerottia cupreicauda Berlepsch & Hartert, p. 84.
