all of which vaiy from a light buff (even almost white on edges of 

 scapulars) to rich fulvous. These variations are probably due to age, 

 the parts becoming darker with successive molts. In two females from 

 MariveleS; Luzon, the buff spot on first primary does not reach the shaft.

"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 mindatiensis, which appears 

 to be closest to the form of C. affinis inhabiting Celebes." (Mearns.)
