In the adult plumage of this species, the principal variation is in the continuity or 

 distinctness of the anterior light band on I he tail, and the extent and depth of slnule of 

 the brown beneath. The lirst feature is characteristic of most specimens, oidy one 

 (r)r),!)St», ^, Costa Uicn) lu'ing without it; it is liroadest and most conspicuous, as well as 

 less concealed by the coverts, in the females, and this a|ip('ars to be the principal sexual 

 dilference. The dull brownish-rnfous of th(> under parts is most prevalent in a spc'cinion 

 I'roin Mirad(U', Mexico (.'K»,8!).j, 9 ' 'September ; T)r. Sartorins), in which specimen the 

 breast is almost continuously of this color, and the lower tail-coverts are strongly barred 

 (or transversely spotted) with the same; the ground-color l)eneatli is also more ochra- 

 ceous than in any other individual. In the Costa-Rican specimen (the one lacking the 

 anterior tail-band), the Ijrown beneath is quite dilTerent from that of the others, being of 

 a much more ashy shade ; the lower tail-(.'overts are also inmiaculate. The lirown mark- 

 ings beneath are most sparse in 20,38it, from Coban, Vera Paz (January ; 0. Salvin) ; 

 in this, also, the tail-bands ar(! very distinct, ami almost while. 



A young bird from Costa Rica (.'5i),41'2 ; Dr. Frantzius) is exactly similar to No. 27,048, 

 from Fort Garry, Selkirk Settlement.
