THE GREEN-RUMPED DOUBLE-COLLARED 
SUN-BIRD. 
Nectarinia cldoropigia , Jardine. 
[PLATE III. 
The third bird which we alluded to, as allied to 
these, formed part of a small collection brought to 
this country on the return of Dr. Stanger, in 1841, 
from the Niger expedition, and kindly entrusted to 
us by Mr. Waterhouse. One specimen only ap- 
peared among these, but Dr. Stanger allowed us 
to compare a second at Manchester, which corre- 
sponded with that previously seen. Its nearest 
connexion is with the first, or Lcsser-collared Sun- 
bird, for which it was first mistaken ; and while it 
presents considerable variations, it may still remain 
a question how far local circumstances may influ- 
ence varieties, and also whether the birds from that 
part of the African coast continue constant in the 
markings, &c. which seem to separate our two 
birds. The distinctions are a less size and less pro- 
portional length of the wings and tail ; the want 
nearly of the blue collar, that being indicated by a 
deeper green, slightly tinted with bluo ; by the 
under parts and flanks being pale oil-green, whereas 
they are brocoli-brown in the other; and by the
