in the figure, and the notice of them in the 

 description is liable to objection. They are soft, 

 full, and snowy white. For this reason we sub-

 pecies, from a specimen in Mr. Gould's col- 

 lection. 



Trochilus (Spathura) Underwoodii. Plate XII. 



Top of the head, back, and upper parts in 

 general, of a rich golden green ; a band of white 

 crosses the rump. The throat and chest are 

 covered with scale-like feathers,- of a refulgent 

 emerald-green ; abdomen, dusky green ; tarsi, 

 clad in full soft downy muffs, of snowy white, 

 obscuring the toes; tail, deeply forked, the 

 outer tail-feather on each side running out to a 

 great length, becoming filamentous as it pro- 

 ceeds, and terminating in a racket-shaped ex- 

 panse or vane ; the external margin of these long 

 tail-feathers is white. 



This species is a native of Santa Fe de Bogota, 

 and the Caraccas. Until recently its locality 

 was unknown.
