15. PANYCHLORA. Type. 



Panychlora, Cab. ^- Heme, Miis. Hein. iii. p. 49 (1860) P. aliciffi. 



Range. Colombia and Venezuela. 



This genus is closely related to CldorostUhon, and is sometimes 

 united with it ; but the interramal space is more feathered and the 

 tail has the peculiar shining colour, characters which serve to separate 

 Panychlora from Chlorostilhon. Some of the species, such as P. in- 

 expectata, P. eucMoris, and P. poorimani, are very closely allied, and 

 may prove to be undefinable. The uncertainty of the exact origin of 

 the specimens before me renders it expedient to leave their position 

 at present in some doubt.
