Cayenne examples of this species, but not sufficient to lead me to 

 consider them distinct. 



3. Nemosią guirina, sp. nov. 



Nemosią guira, Sclater, P. Z. S. 1855, p. 155. 



Flaveseenti-olivacea, superciliis longis cum plaga cervicali utrin- 

 que conjunctis Jlavis : giitture et capitis lateribus nigris : dorso 

 postico cinnamomeo, pectore item cinnamomeo sed saturatiore et 

 magis castaneo : abdomine cinerascenti-Jiavido, crisso Jlavicante. 



Long. totą 50, alse 2'9, caudse 2'0. 



Hab. New Grenada, Bogota ; East Peru. 



Three specimens of what woiild at first sight appear to be N. guira, 

 iu my possession, two of which are from New Grenada and the third 

 from Peru, offer such a marked differenee in tbe length of the wing 

 on comparison with specimens from the eastern coast, that I cannot 

 avoid separating them specifically. They are also distinguishable, as 

 the yellow colour is more developed on the sides of the neck, but 

 does not form a band between the breast and black throat, as in 

 N. guira. And in the N. guirina the breast has more of a deep chest- 

 uut tinge, which extends quite up to the black throat. 



Perhaps d'Orbigny's Bolivian N. guira may be rather referable to 

 this species than to the previous bird.
