GREEN-HUMPED DOUBLE-COLL. SUN -BIRD. ] 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.
