Genera of Humming Birds. 37 



This species, received by Mr. Bourcier from Columbia, was 

 dedicated by him to his friend, the well known Ornithologist, 

 Mr. Edouard Verreaux. 



Its proper name should be the Columbian Coquette, as this 

 species is restricted to Columbia, as far as I know. 



I have seen a young male specimen from Columbia in the 

 collection of my friend, Mr. Eugene Simon, of Paris. It was 

 without the elongated feathers of the neck, which were replaced 

 by a beautiful metallic grass-green throat. My friend, 

 Mr. Simon, has described this bird and given the name of 

 L. insignibarhis ; but I am quite certain that it is only the 

 livery of a young male of L. ver7'eauxi, just before taking the 

 plumage of an adult bird. 



52. LoPHORNis Hauxwelli, N. Sp. 



HauxwelVs Coquette. 



Le Lophornis d'Hauxwell. 



Habitat. — ^Nauta, Upper-Amazons. 



Male. — Very much like the preceding species, with which it 

 has always been mixed, but having two fine adult pairs of this 

 bird, collected by Mr. Hauxwell, at Nauta, I am able to point 

 the differences which exist between the two species. All the 

 upperside of this species is bronzy-green and not dark green as 

 in L. verreauxi, the band across the rump is pale rufous in both 

 sexes, the tail is reddish-pm'ple with external margins dark 

 brown instead of purplish-bronze, the uppertail-co verts are 

 crimson-purple, instead of bronzy-purple. The underside is 

 exactly the same as L. verreauxi. 



The female has also the back of a lighter green than 

 L. verreauxi, the chin and line under the eyes is pale buff, the 

 flanks are golden-green spotted with buff, the tail is grayish at 

 base, then dark bronze, nearly black, with the lateral feathers 

 tipped with a large grayish spot. 



I dedicate this species to Mr. Hauxwell, its discoverer.
