ous ; all the. other wing edgings more or less strongly tinged with bufFy 

 or cinnamomeous instead of being pure white; superciUary stripe 

 narrower and shorter, posteriorly not reaching beyond the auriculars ; 

 entire upper surface strongly rufescent brown instead of grayish 

 brown ; and even wings and tail more rufescent. 



Description. — Type, adult female, No. 181577, U.S.N.M.; Solombo 

 Besar Island, Java Sea, December 4, 1907; Dr. W. L. Abbott. Fore- 

 head brussels brown; crown between brussels brown and clove 

 brown; both forehead and crown with rather broad shaft streaks of 

 fuscous black, the crown slightly streaked with buffy whitish, its 

 ground color passing posteriorly into the hght olive brown of the 

 back; back and scapulars between olive brown and buffy brown, 

 with narrow, barely discernible, dark clove brown shaft streaks; 

 rump smoke grsij with paler terminal bars; upper tail-coverts smoke 

 gray with paler tips, the longest feathers darker, more brownish, with 

 hair brown subterminal bars and grayish white tips ; tail fuscous, the 

 two middle feathers narrowly margined on both webs with brownish 

 white, the remaining rectrices with large terminal white areas, these 

 longest on the outer web, and increasing progressively to the outer- 

 most pair, which has about one-third of the inner web and two-thirds 

 of the outer web white ; wings fuscous, but the whole basal portion of 

 the inner vanes of wing-quills white, this occupying two-thirds or 

 more of the length of each feather on the inner primaries and outor 

 secondaries; quills narrowly margined on exterior webs with creamy 

 white or light buff, this broadest and most buffy on terminal portion 

 of secondaries and tertials; primary coverts narrowly tipped with 

 buffy white; greater wing-coverts narrowly edged and more broadly 

 tipped with the same; median coverts very broadly margined on 

 both sides with light pinkish cinnamon or whitish ; lesser coverts also 

 edged broadly on both vanes with whitish, pinkish cinnamon, and 

 cinnamon, leaving, as on the median coverts, only a pointed central 

 area of fuscous; lores olive brown, but much mixed with white; broad 

 postocular stripe brown like the crown; superciUary stripe, sides of 

 head and neck, and entire lower surface, including lining of wings, 

 creamy white, more definitely tinged with cream color on the breast, 

 sides of neck and of body; the flanks, sides of breast and of body 

 somewhat obscurely and irregularly barred with pale mouse gray; 

 thighs mixed light mouse gray, light drab, and dull white; bill (in 

 skin) fuscous, the tip darker, the basal portion of mandible pale 

 brownish. Total length (in flesh), ^ 192 mm.; wing, 90; tail, 81; 

 exposed culmen, 15.5; tarsus, 23; middle toe without claw, 14.5. 



Of this remarkably distinct bird Doctor Abbott obtained but a single 

 example, an adult female. It is in process of molting some of the con- 

 tour feathers, but wing-quiUs and rectrices seem to be intact. The char- 

 acters it exhibits preclude its reference to any genus hitherto described.
