This Pyranga seems sufficiently distinct from either of the 

 above-named species to justify its separation. The chief cha- 

 racter is the paler red throat and abdomen in contrast to 

 the dark chest and flanks. 



Mr. Whitely's specimens were obtained in January 1882.

Obs. O. flammicipiii et 0. fratri similis, sed corpore subtus 

 albo nigro guttato distinguendus. 



This species seems to be distinct from both O.flammiceps 

 of Brazil and 0. frater of Central America, the under surface 

 being nearly pure white spotted with black; in the allied 

 birds this part is pale green with black spots. In the mark- 

 ings of the wing-coverts it is somewhat intermediate between 

 the other species, the coverts being spotted, though not so 

 clearly as in O, frater ; the inner secondaries, too, have a yel- 

 lowish outer margin. 



In the male bird the outer primary has the barbs pointed 

 and recurved, so that the edge of this feather is strongly ser- 

 rated. Both the allied species have this feature ; but it seems 

 carried to greater development in 0. hypoglaucus than in 

 either of the others. The shape of each hook is somewhat 

 similar to that which is found in the genus Stelgidopteryx.
