Young male. — Very different in coloration from adults. Pileum, 

 hindneck, back, scapulars, rump, upper tail-coverts, tail, and remiges 

 olive-brown, paler and slightly cinnamomeous on forehead; inter- 

 scapulars, scapulars, and proximal secondaries with a terminal, 

 broadly triangular spot of rufous-cinnamon or mikado brown, 

 margined anteriorly by a more or less distinct bar of darker olive- 

 brown, or dusky; upper tail-coverts and rectrices tipped with 

 rufous-cinnamon, the former with a sub terminal bar of dusky; wing- 

 coverts rufous-cinnamon or mikado brown, passing into olive-brown 

 basaUy; remiges edged, more or less distinctly, with rufous-cinnamon; 

 under parts mostly pale brownish buff, the chest dull rufous-cinnamon 

 or mikado brown. 



Young female. — Upper parts, including wing-coverts, dark olive- 

 brown or brownish olive, faintly glossed with bronze-greenish; 

 wing-coverts tipped with light russet or mikado brown, producing a 

 conspicuous transverse spotting, the scapulars more narrowly tipped

While convinced that subdivision of this species, to a gi-eater or less extent, will 

 eventually be required, I am not able, even with a very considerable amount of 

 material, to make out satisfactorily any well-defined forms. Few other laud birds 

 have so extensive a geographic range; for, while many species inhabit practically the 

 whole extent of continental tropical America, this occurs also in many of the West 

 India islands. The series examined is, however, very meager from certain parts of 

 the range of the species, and many more specimens from such localities will be neces- 

 sary to determine the question of subspecific division. The individual variation, both 

 in measurements and coloration, is very considerable in any locality, and this, of course, 

 must be taken into account. As may be seen from the above measurements, speci- 

 mens from British Honduras and southward average decidedly smaller than those from 

 Mexico and the West Indies.
