(2285) Schizoeaca fuliginosa (Lafr.). 

 Synallaxis fuUginosa Lafr., Rev. Zool., 1843, p. 290 (Colombia). 



Inhabits the Paramo of the Central and Eastern Andes, descending to 

 the upper border of the Temperate Zone. Specimens from the Central 

 Andes appear to average shghtly darker in color. While evidently a repre- 

 sentative of the Ecuadorian S. griseo-murina (Scl.) a specimen from Al- 

 maguer shows no approach toward that form.

Met with only on the Paramo of Santa Isabel in the Central Andes. 

 Four specimens agree in color with a topotypical series from Chimborazo 

 but average more narrowly streaked above.

Inhabits the Temperate Zone of the Eastern Andes. In view of the 

 occurrence of S. a. media at Quito, it might be expected that specimens 

 from south of Quito would be intermediate between media and azaras, but 

 the distributional problem is much involved by the fact that seven speci- 

 mens from Zaruma (6000 ft.), one from Loja (7000 ft.), and one from Na- 

 ranjo (2000 ft.) in southern Ecuador, are all clearly referable to elegantior 

 of Bogota ! It is sufficiently surprising to find in this group identical forms 

 occupying the Temperate Zone in the Bogota region and the Tropic Zone 

 near Guayaquil, but the case is rendered still more puzzling by the occur- 

 rence between these points of another form with which, at least from the 

 north, intergradation with the first-named form appears to be proven.
