Mr. Whitely's collection contains six specimens of this 

 species, all from the Merume Mountains, and the first 

 examples of any Chamieza we have yet seen from Guiana. 

 In its colour above the present bird closely resembles C. 

 nobilis of Gould, of which we have specimens from Ecuador ; 

 but the fulvous throat and breast distinguish it from this 

 species, as weU as from all others of the genus. 



HeMISTEPHANIA JOHANNiB. 



This species appears to be quite common in the Merume 

 Mountains, as Mr. Whitely sends many specimens in his 

 collection from that district. The adult males agree so 

 closely with Colombian examples of the true H. johannce 

 that we are unable to separate them. The only difference 

 we can trace is that the shining forehead of the Guiana- 

 bird is of a very slightly bluer shade of purple than that 

 of the Colombian one, but not enough to justify the birds 

 being separated. Besides adult males, we find in Mr. 

 Whitely's series two forms of female — one with a pale 

 greenish blue forehead, the other without any bright co- 

 louring. The former of these exactly corresponds with the 

 Colombian bird described by INlulsant as Doryphora euphro- 

 syn(B, and we are driven to the conclusion that the bird so 

 called is nothing but the female of T>. Johanna. It is most 

 probable that birds with the bright forehead are old females, 

 and those not so adorned younger birds ; but the latter may 

 still be adult.
