17. SPERMOPHILA. 129 



sides of the face. This is the stage of plumage described by Count 

 von Berlepsch as a distinct species, S. olivacea, supposed to inhabit 

 Ecuador. Similar birds are, however, found in other countries, and 

 the one described above is from Peruambuco. Ecuador skins are 

 certainly brighter in colour below, and the female is more saffron- 

 yellow underneath; the wing-spot, always small, is also obsolete in 

 specimens from Ecuador, but it is such an inconstant character that 

 every intermediate grade is found in the Museum series. 



Adult female. Different from the male. General colour above 

 olive-brown ; lesser wing-coverts like the back ; median and greater 

 coverts dusky brown, edged with olive-brown, and tipped with 

 whity brown, forming an indistinct double bar ; bastard-wing, 

 primary-coverts, and quills dusky brown, edged with olive-brown, 

 broader on the secondaries ; tail-feathers dusky brown, margined 

 with olive-brown ; crown of head and sides of head like the back ; 

 lores and feathers round eye buffy white : ear-coverts olive-brown 

 streaked with whitish ; cheeks and under surface of body ochreous 

 buff; breast and abdomen buffy white with a yellow tinge ; sides of 

 body and flanks olive-brown ; thighs and under tail-coverts whitish 

 tinged with ochre ; under wing-coverts and axillaries white, washed 

 with ochreous yellow ; quills below dusky, ashy along the inner 

 edge, whitish towards the base. Total length 4*1 inches, culmen 

 0-35, wing 2, tail 1*6, tarsus 0-55. 



Yomifi males at first resemble the adult female, but show a good 

 deal of black on the throat and crown, all, however, concealed by 

 the overlying greenish plumage. 



Hab. Brazil, Guiana, Venezuela, Colombia, extending into 

 Panama ; Ecuador and Peru.
