Mindanao (Mearns).

“Adult male.—Similar to Caprimulgus affinis but differing as follows: General coloration darker. Upper parts hair-brown, finely vermiculated and dotted with clove-brown, light gray, and black; scapulars marked with broken spots of cinnamon; first four primaries barred across their middle with pure white except the outer web of the first primary, this band varying from 12 to 24 mm. in width on the differing feathers, widest on the fourth; outer tail-feather white only on the terminal half, the basal half being cinnamon, clouded and irregularly cross-banded with brownish black, and the tips of both webs clouded with brownish black; second feather similar, but with much less of the dusky clouding at tip; lower abdomen and thigh-coverts cross-banded with pale sepia-brown; under tail-coverts and anal region buff, without cross-bands; upper third of tarsus feathered. Length of skin, 205; wing, 163; tail, 100; culmen, 8; tarsus, 19.

“Individuals vary greatly in the character and size of the punctate and vermiculate markings of the upper surface. The vague black cross-bands of the middle pair of tail-feathers are somewhat V-shaped (open apically), numbering about eight.

“In true affinis, adult males have the outer tail-feather all white, and the lower abdomen, thigh-coverts, and under tail-coverts ‘uniform pale fulvous buff.’ In C. affinis griseatus the bars are spread over the whole of the lower abdomen, thighs, and lower tail-coverts, and the color is more grayish rufescent than in C. affinis mindanensis, which appears to be closest to the form of C. affinis inhabiting Celebes.” (Mearns.)
