Adult male.—Bright golden yellow and black; forehead and part of crown yellow; lores, a wide space about eye continued with a broad band across crown and occiput black, forming a broad crescent-shaped mark; wings black, some of the primaries narrowly edged with gray; tertials tipped with yellow; secondary-coverts, axillars, wing-lining, and edge of wing bright yellow; rectrices black, tipped with yellow, the yellow tip narrowest on the central pair and gradually wider on each succeeding pair to the outermost; entire under parts bright yellow, not so deep as the back. Iris pale pink; bill pinkish flesh-color; legs plumbeous; nails horn-color. An adult male from Luzon measures: Length, 305; wing, 150; tail, 104; culmen from base, 34; bill from nostril, 24; tarsus, 25.

Adult female.—Similar to the male, but the mantle with a dusky, slightly olive, wash contrasting strongly with the clear golden yellow of hind neck. A female from Mindoro measures: Wing, 149; tail, 112; culmen from base, 34; bill from nostril, 25; tarsus, 26.

Young.—Above olive-yellow or golden olive; the crescent crown mark obscure and more or less dusky olive in color; tertials and rectrices dusky, washed with olive; under parts much paler than in the adult, near lemon- or gamboge-yellow; feathers of breast with distinct black shaft-lines. As the bird becomes older the crescent-mark on the head becomes better developed and the shaft-marks on the breast become less distinct. The bill is dusky brown in immature individuals.

Three eggs of the Philippine oriole, taken by Whitehead at Cape Engaño, Luzon, on April 15, 1895, are thus described:

“Shape ovate. Pure white, with scattered spots and minute dots of deep blackish brown, and a few faint under-markings of slate gray. Measurements 32 mm. by 23 mm.” Two eggs from Fuga, April 5, 1895, are “similar to the above.” Measurements 33 mm. by 22 mm.
