TOPAZ THROATED HUMMING-BIRD. 
Trochilus pella Linn’.eus. Variety. 
Plate XXV. 
We have given a copy from Lesson of a curious 
variety of this bird, exhibiting an imperfect state of 
albino, and in which the pure white feathers con- 
trast beautifully with the gorgeous plumage of the 
other parts, which did not seem to want any thing of 
their brilliancy. It has been thought by some that 
the occurrence of white feathers, or of pale coloured 
varieties, did not take place in those birds having 
plumage of shining or metallic lustre. Of this the 
accompanying plate will be a proof to the contrary, 
where it is exhibited in one possessing those qualities 
to the utmost ; and we have specimens of one or two 
other species where it also occur.s. As familiar in- 
stances of it, we may mention the common Starling, 
Pheasant, and Peacock.
