We have hitherto considered this bird inseparable from the Guiana M. erythrurus, 

 but having received a fair series of specimens from British Guiana we are able to make 

 an accurate comparison, and find that the Guiana bird can be distinguished by its 

 greyer throat and less olivaceous head and back; the belly, too, is paler fulvous. 

 M. erythrurus seems to be strictly confined to Guiana, whereas the bird we now 

 describe enjoys a wide range, reaching Costa Eica in its north-western extension. It 

 appears to be not uncommon throughout the State of Panama.

Some birds of this species have the crest rufous, others yellow, and we suspect that 

 the former will prove to be males, the latter females, but dissected specimens do not 

 altogether confirm this view. 



Myiobius ncevius has a very wide range over Tropical America, where it is one of 

 the commonest birds, skins being nearly always found in the trade collections of 

 Brazil and elsewhere. The bird of Western Ecuador has been separated under the 

 name of M. crypterythrus and that of the eastern slope of the Andes of Ecuador as 

 M. cryptoxanthus, both birds being hardly separable from M. ncevius. 



From Central America but few specimens have reached us, and those all from the 

 State of Panama. Some of these came from the low-lying forest tract crossed by the 

 Panama Eailway, others from the more mountainous parts further to the westward. 



We have no account of its habits in Central America, but in the Argentine Eepublic,
