102 Genera of Humming Birds. 



rectrices green, lateral green at base, rest steel-blue with 

 white tips. 



I have a large series of this species, some collected by myself 

 at Costa-Rica and Panama, others sent from Columbia, and 

 some collected by Hauxwell at Nauta, Peru. The specimens 

 from Costa-Rica, Panama and Peru, are not so bronzy on nape^ 

 and have a wide ultramarine-blue band on back ; but other- 

 wise they are exactly the same as the Columbian specimens^ 

 and I don't think necessary to maintain the name of T. venus fa 

 for these specimens. 



I have also one pair of these birds collected at Valencia, 

 Columbia, in which the shinino- emerald-green of the throat 

 covers only the throat and upper-part of the breast. The 

 neck, back and rump are all green, without the bronzy tinge 

 constant on all the other specimens which I have under the 

 name of T. columbica. The female is also distinct, having the 

 flanks and abdomen green. If it should prove a different 

 species, I propose the name of Thaliirania valenciana for 

 this bird.
