LENGTH, according to Monsr. Viellot's figure, 

 >about four inches : bill rather long in proportion, 

 to the bird : colour greenish-brown above ; velvet- 

 black beneath, except the throat to a considerable 

 distance on the sides and down the neck, which is 

 of a bright gold-green : the black colour of the 

 under parts is deepest on the breast : across the 

 vent is a whitish bar : the tail is violet, (in Monsr. 

 Viellot's figure violet-lilac,) slightly tipped with 

 black. In some individuals the belly is said to be 

 white. 



This species appears to be considerably allied to 

 the Trochilus porphyrurus or Violet-Tailed Hum- 

 ming-Bird, from which however it differs in the 

 colour of the neck and throat.
