the belly ; under wing-coverts like the breast ; upper mandible

 differing in the more greenish back, less rufous head, and yellowish 

 belly.

 P. Z. S. 1874, p. 538 ; id. Orn. Per. ii. p. 315. 



Like M. aurantiiventris, but smaller, not green above, and much 

 brighter on the under surface. (Cabanis.) 

 Hab. Central Peru. 

 This species I have not yet met with.

 Mitrephanes capitalis, Ridgw. P. U. S. N. M. vi. p. 403 (Nicaragua). 



Above olive-green ; head slightly crested, cinereous; lores whitish ; 

 wings and tail dark ashy, tips of wiug-coverts and outer margins of 

 external secondaries rufous : beneath, throat whitish, breast dark 

 ochraceous brown, belly and under wing-coverts yellow ; bill dark 

 horn-colour ; feet pale brown : whole length 5 inches, wing 2*4, 

 tail 2-2. 



Hab. Costa Rica. 



A very distinct species, hitherto only known from the typical 

 specimen. It may perhaps, as Mr. Ridgway suggests, be best 

 placed in this genus, but has shorter wings and a larger beak than 

 M. pJiosocercus.
