SWAINSON« HUMMING-BIRD. 
Trochilus Swainsonii Besson. 
Plate XXX. 
Be Colibri Swainson, Trochilus Swainsonii, Le Swainsou, 
Trochilidies, pi. kvi. 
In a former Plate we gave a bird from Lesson un- 
der the above title, and our only reason for again 
introducing another Humming-Bird with the same 
name is, that this group of birds will stand under 
Pcethornis Stv., and that this species will be placed 
in our Systems as P. Swainsonii ; the other as Cy- 
nanthus Swainsonii. 
It is a native of Brazil, and is about three inches 
in length. The tail does not shew the roundness 
or graduation which is so conspicuous in the others ; 
like them, however, the centre feathers are green ; 
the others of an ochreous-yellow, barred with black, 
and with a white tip. The upper parts are of a 
brilliant brownish-green ; the under parts of a red- 
dish chestnut, of a tint nearly uniform.
