narrower, lighter, und more greenish-blue bars on the crown- 

 t'eathers, which form a slight crest. The blue tips of its 

 wing-coverts are darker, and much less noticeable; the same 

 is true o£ the scapulars. They are nearly black. 



From Corijtlwrms cristata it differs widely in the colours 

 of its lower parts, as it does also from C. nais, with whicli I 

 have carefully compared it. These hist two forms have both 

 nmch longer crests and blue lateral margins on the crest- 

 feathers ; yet a few crown-feathers of C. leopoldi show blue 

 edoings as well, the blue of the cross-bars being intermediate 

 in shade between the deep blue of nais and the " malachite " 

 in cristata. 



A full description of the adult female of C. leopoldi 

 follows : — 



Feathers of crown elongated, but none more than 14 mm.

 and broadening as it goes back to the nape. The usual
