GENERA AND SPECIES. 133 



bronzy-brown with green reflexions, each feather 

 being tipped with buff, paler on the two centre 

 ones; wings deep purplish-brown; outer side 

 of tarsi clothed with short buffy-brown feathers ; 

 feet and inner part of tarsi yellow.

The female resembles the male in colour, but 

 is smaller in size. In Gould's collection. 



The nest is attached, by means of spiders' 

 webs, to the extremity of a-leaf ; it is composed 

 of fine silky and cottony fibres, mixed with 

 spiders' web and portions of a fungus resembling 

 wool. In form it is deep, round and cup-shaped, 

 and tapers to a lengthened point at the bottom. 



Locality: Southern Brazil, Amazon. 



This species is perfectly distinct from the 

 Trochilus Pygm&us of Spix, from the northern 

 parts of Brazil, and from the Trochilus rufigaster 

 of Vieillot, said to be from Cayenne. Lesson's 

 description of the latter agrees with the present 

 species, but the figure which accompanies it, 

 agrees neither with this nor any known species. 



The Trochilus rufigaster of Vieillot is described 

 in the Naturalist's Library, Ornith. vol. i. p. 83. 

 pi. 4. under the title of the Rufous-bellied Hum- 

 ming-bird. In the same work, vol. ii. p. 127, a 

 Trochilus rufigaster, Lesson, is described as the 

 Bed-bellied Humming-bird. To both these birds 

 is applied as a synonym the term Colibri a ventre 

 roussatre of Temminck, pi. col. tab. 120. 



Trochilus Petrii, Bourc. Locality: Brazil, 

 Minas Q-eraes. In G-ould's cabinet.
