178 SYNOPSIS OF THE TROCHILHXffi. 



11. P. MAZEPPA, Mazeppa Humming-Bird. Colibri Ma. 

 zeppa, Less. Troch. iii. Above golden-green, be- 

 neath pale chestnut ; tail uniform chestnut, barred 

 with black at the tip, centre feathers golden-green. 

 Inhabits French Guiana. 



PL. XXX.. VOL. II 12. P. SWAINSONII, Swainson's Hum- 



ming-Bird. Colibri Swainson, Less. Uroch. Ixvi. 

 Golden-green above; beneath, chestnut-red; tail 

 even, chestnut, barred with black and tipped with 

 white. Inhabits Brazil. 



13. P. LEUCURUS, White-tailed Humming-Bird Lath. 

 Trochilus leucurus, Less. O. M. xx. Above golden, 

 green ; throat with a patch of chestnut ; breast gol- 

 den-green ; belly and vent grey ; tail white, except 

 the centre feathers which are green. Inhabits 

 Dutch Guiana, Surinam. 



14. P.? SIMPLEX. Colibri simple, Less. Col. xxiii. 

 Golden-green above, beneath chestnut; the throat 

 indistinctly in the form of a gorget, purplish; vent 

 white; tail nearly equal, but rather hollowed in the 

 centre, black, outer feathers tipped with white. 



This seems to be a bird in immature plumage, and more allied 

 to Cynanthus. Trochilus multicolor, we have every reason 

 to think, is a made-up specimen, but would stand here. 



15. P.? CHRYSURUS, Yellow-tailed Humming-Bird. - 

 Oiseau-mouche chrysure, Ornismya chrysura, Less. 

 O. M. siipp. iv. Uniform golden-green ; tail red- 

 dish-yellow, deeper at the tip, rounded. Inhabits 

 Brazil. 



1C. P.? AMAZILI. Orthorhynchus amazili, Less. Zool de 

 la Cog. xxxi. Crown, throat and breast, emerald- 

 green ; upper parts golden-green ; vent reddish, 

 yellow; tail bright chestnut, nearly square. Inha- 

 bits Peru. 



The last bird Is described as new in Lesson's Zoologie de la 

 Coquile, and, with the preceding one, is introduced here in 

 doubt. They shew a strong alliance to both this form and 

 Cynanthus.
