BRILLIANT HUMMING-BIRD. 327 



fine glossy green, with blue reflexions on the sides 

 of the neck : wings violet-black ; tail indigo-blue, 

 with a mixture or cast of green : lower part of the 

 belly white. The tail is rather rounded, in which 

 respect it seems to differ from the Sapphire and 

 Emerald Humming-Bird, of which it is probably 

 no other than a mere variety. It should be added 

 that the upper mandible is black, and the lower 

 white. Native of Guiana. 



To the description of the two brilliant Hum- 

 ming- Birds above-detailed, viz. the sapphirinus and 

 smaragdo-sapphirinusy I shall venture to hint a 

 degree of doubt whether the two kinds may not in 

 reality constitute one and the same species, and 

 whether the different distribution of colours and 

 comparative variation of splendor occasionally ob- 

 served, may not be rather owing to sexual dif- 

 ferences and the various stages of plumage than 

 to a real specific difference ; the general appear- 

 ance being nearly similar in both.
