GREEN-RUMPED DOUBLE-COLL. STJN-BIRD. 1 73 
served for the description of C. chalyleia, in the 
“ Birds of Western Africa,” may have been that 
now before us ; and the “ greenish tinge” on the 
narrow blue collar, and the “ tail-coverts banded 
with greenish blue,” almost lead us to believe that 
this has been the case. 
In Le Vaillant’s description of “ Sucrier a plastron 
rouge,” a bird inhabiting the forests of Auteniquoi, 
nearly allied, is described as almost intermediate 
in colouring between the greater and lesser collared 
birds, the crimson band being less in breadth ; and 
what at once distinguishes it, it has all the red 
feathers transversely marked with lines of a rich 
golden green. By referring back to our descrip- 
tion, it will be seen that the red band in our present 
bird is partially marked in this way.
