Chrysoptilus nigroviridis GRANT: "Size rather larger than either C. melano- 

 leemus or C. cristatus; above yellowish olive not so bright as in C. cristatus; rump as 

 in C. cristatus, but paler; a strong indication of black behind the malar stripe, though 

 nothing like to the extent in C. melanolcmus; ear coverts washed with golden buff; 

 below yellowish olive, the chest strongly washed with orange. This appears to be 

 quite a distinct form differing from C. melanolcemus in having the golden yellow 

 rump and being greener below and from C. cristatus in having an indication of black 

 behind the malar stripe and by the orange on the chest." (Grant, /. c.).
