bright lemon-yellow with dusky shaft-lines; primaries, outer secondaries, 
primary-coverts, and alula-feathers blackish, edged with ashy gray; 
inner webs of primaries edged with white; secondary-coverts and inner 
secondaries edged with dark olive-yellow ; rectrices blackish, the outermost 
pair each with a large yellow spot (about 18 mm. in length) at tip of 
inner web, the spot gradually decreasing in size on each succeeding 
feather. A male from northern Negros measures: Wing, 122; tail, 86; 
culmen from base, 24; tarsus, 21. 
Female.-—The female resembles the male in colors, but is slightly 
smaller and has a smaller yellow spot on the outermost rectrix. A 
female from northern Negros measures: Wing, 111; tail, 78; culmen 
from base, 23.5; tarsus, 21. 
Steere’s oriole differs from the Basilan oriole in having the inner 
webs of the primaries white and the yellow spots on the rectrices much 
larger.

“Had we known the habits of the orioles of this type as well at the

pines. The peculiar note which they utter at frequent intervals when
