SETOPHAGA. 



261 



Setophaga aiirantiaca. 



Setophaga aurantiaca, Baikd, n. s. 

 Hab. Costa Rica. 



Upper parts, with head and neck, plumbeous, without any tinge of olive ; 

 wings and tail black, the quills edged slightly with plumbeous. Crown orange 

 brown, margined on the forehead and above the eyes with black. Fore part 

 of the neck blackish. Beneath yellowish-orange ; the crissum and inside of 

 wings white : the tibiae and edge of wing plumbeous. Rather less than the 

 terminal half of outer tail feather, and a diminishing amount on the second 

 and third feathers, white, the white extending farther towards the base on the 

 outer webs of the outer feather ; the black extending forwards externally on 

 the edge of the second and third feathers. Iris black. 



The sexes do not appear to differ. Some specimens are, however, of a deeper 

 orange. A young bird (30,493), not fully fledged, is very similar, but lacks 

 the brown crown. The orange of the under parts is very deep and distinct. 



Length (No. 33,280, 9), 5.00; wing, 2.45; tail, 2.57; gape of bill, .60; 

 tarsus, .75. 



This species is very similar to S. verticalis, of Bogota, but differs 

 in having the under parts yellowish-orange, rather than clear gam- 

 boge yellow. The throat is apparently darker. The black of the 

 forehead and sides of the vertex-spot I do not find in the speci- 

 men before aie of verticalis, nor are they mentioned in the descrip- 

 tions. There is more white on the tail feathers oi verticalis, involving 

 more than half of the inner web and two-thirds of the outer. There 

 is no trace in aurantiaca of the a.shy margins of the tail feathers 

 mentioned by D'Orbigny. 



Setopliaga torquata. 



Sefo/thar/fi. tnrqndta, Baird, n. s. 

 Hab. Costa Rica. 



Upper parts, continuous with a narrow pectoral collar ashy plumb ous, 

 with a tinge of olive above ; the collar more dusky. A narrow frontal line, 

 entire sides of head, including lores and circum-ocular region, and under parts, 

 bright yellow. Crissum and inside of wings pale yellowish ; edge of wing darker
