We have hitherto considered this bird inseparable from the Guiana JZ. 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 
ereyer 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 Rica 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 nevius 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 VV. crypterythrus and that of the eastern slope of the Andes of Ecuador as 
M. cryptoxanthus, both birds being hardly separable from M. nevius. 
From Ceutral 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 Railway, others from the more mountainous parts further to the westward. 
We have no account of its habits in Central America, but in the Argentine Republic,
