primaries with six rufescent spots internally, which on the secondaries 

 form irregular narrow cross bands ; the last of the secondaries grey- 

 ish fulvous, mottled with pale brown, and across the shaft with six 

 black lines ; the first quill has on the basal half four obsolete ru- 

 fescent marginal spots ; the shafts are black, and dark brown 

 beneath ; tectrices of the primaries black ; tectrices of the seconda- 

 ries black, with rufescent marginal and apical spots, mottled minutely 

 with dusky ; the remaining upper wing-coverts are marked in the 

 same manner, but the rufous spots are smaller, so that the smallest 

 upper wing-coverts near the cubitus are black with narrow rufous 

 edgings ; the greater median wing-coverts show a large fulvescent 

 apical patch on the outer web, forming a crossband-like conspicuous 

 mark ; under wing-coverts blackish brown, barred narrowly with 

 rufous ; feathers, the region beneath the eye, along the angle of 

 mouth, chin and sides of throat rufous, with black apical edgings ; 

 throat apparently divided into two, with patches, by a narrow rufous 

 black-barred median line ; crop and breast of a rufous-brown ground- 

 colour, each feather towards the tip lighter, changing into greyish 

 fulvescent, finely mottled with dark brown, forming speckled cross 

 lines, and a narrow black shaft-stripe ; remaining underparts pale 

 fulvescent, with obsolete narrow dark cross lines, broader and more 

 distinct on the under tail-coverts ; three outer tail-feathers black, 

 with nine rufous cross bands, which on the outmost are narrower 

 (here ten), on the second and third broader, and mottled with dusky ; 

 on the inner web these rufous cross bands are only indistinctly indi- 

 cated ; the fourth tail-feather shows the nine rufous cross bands 

 broader, distinct also on the inner web, and mottled more with 

 dusky ; the two middle tail-feathers have a rufous-brown ground- 

 colour, internally changing into grey-brown, speckled with dusky, 

 and nine irregular black bars. Bill black, bristles (eight) strongly 

 developed, black ; feet and nails hornish brown ; the tarsus feathered 

 at the basal half, rufescent ; shafts of the tail-feathers black. 



Of this species a single specimen was collected by Capt. Heinsohu 

 in the Pelews — a locality whence no Caprimulgine bird has been 

 yet recorded. The specimen is evidently a female; and the male, 

 no doubt, will present some considerable differences ; perhaps we may 

 expect it will have the primaries as well as the outer tail-feathers 

 spotted with white. Although female Caprimulgi are much more 

 difficult to determine, and it might be considered somewhat hazard- 

 ous to establish a species on an isolated specimen, nevertheless we 

 are obliged to do so, having endeavoured to unite this specimen with 

 any of the known species without success. 



C. phalcena seems to come nearest to C. jotaka, Temm., from 

 Japan, and C. stictomus, Swinh. (Ibis, 1863, p. 250), from Taiwan, 

 but may be distinguished, besides strongly contrasting differences in 

 coloration, by its smaller size ; the latter besides has naked tarsi.
