IN the bird now represented, and another species, 

 we see the fork of the tail assuming another varia- 

 tion, in the diminution and again widening of the 

 web, so as to leave a part of the shaft bare of plumes. 

 The present species is, besides, very remarkable for 

 the feathering of its tarsi and base of the toes, which 

 are thickly covered with narrow horny-tike plumes, 

 and I believe is the only instance of that structure 

 among this tribe. All the upper parts are of a golden 

 green, the rump barred with a band of white. A 

 gorget of bright emerald-green, occupies the throat, 

 forepart of the neck, and almost the whole breast, 

 which is immediately succeeded by a deep tint of 

 brownish green. The thighs and plumed tarsi are 

 pure white. The tail, deeply forked, is a blackish- 

 brovvn, the centre feathers tinged with green. The 

 form will be best understood by referring to the ac- 

 companying plate. The country of this species is 

 unknown.
