CINNYRIS CHLOROPYGIUS. 83 



C. reichenowi. It is not without hesitation that I describe a 

 third form in addition to G. mediocris and G. reichenowi from 

 almost the same localities; yet, on the other hand, it seems 

 to be as distinct from G. reichenowi as the latter is from 

 C. mediocris ; and Prof. Reichenow and Mr. Neumann, both 

 authorities in East African ornithology, pronounced it to be an 

 undescribed species when they saw it at Tring." 



The group to which I have applied the name of Double- 

 collared Sunbirds presents several extremely nearly allied 

 forms. These are most readily distinguished by the brown, 

 yellow or ashy shade of the breast below the red collar, and 

 the steel or purple blue shade of the metallic collar and upper 

 tail-coverts ; these characters, coupled with the measurements 

 of the bill and wing, suffice to distinguish e,ach species ; and 

 the females may be generally recognised by the shade of 

 plumage being somewhat similar to that of the abdomen of the 

 full plumaged males.
