NO. 1318. BIRDS OF NORTHWEST SUMATRA— RICHMOND. 493 



coverts, there are indication.s of a second pale bar. Ear-coverts and 

 malar region dark brown (between sepia and clove brown); sides of 

 neck similar, each feather tipped with pale cinnamon; chin, throat, 

 and chest brown (paler than the ear-coverts), barred and tipped with 

 Mars ))rown, the j)ars darker and broader on the latter; breast and 

 sides Mars brown, narrowly barred with blackish brown, with occa- 

 sional lateral white .spots; abdomen, flanks, and under tail-coverts 

 Mars brown, with more numerous lateral white spots, which are sur- 

 rounded l\y dark brown; under wing-coverts and axillaries like the 

 abdoinon, the edge of the wing being more prominently mottled with 

 white; imder surface of wing dusky, with a broad obscure pale bar on 

 the inner webs of the feathers about 95 nmi. from their tips; near the 

 base of each feather there are one or two white spots of irregular 

 shape and size. 



Length, 527; wing, 347; tail, 228; tarsus, 82; bill, from gape, 38 mm. 



"Iris yellow; cere and naked face deep j^ellow; bill horn blue, black 

 at tip; feet yellow, claws black." 



• There is some variation in color shown in this series, especially in 

 th(> markings of the tail, under surface of the wings, and of the throat 

 and chest, ])ut the general appearance of each ])ird is very like that of 

 thetvpe. 



In some 3'ounger individuals many feathers of the scapulars, tertia- 

 ries, and greater wing-coverts are narrowly tipped with white, or have 

 small lateral white spots at the tips, while the black crown feathers 

 ha^'e pale rusty edges. 



The dimensions of this sjiecies are: Males, length, 502-546; wing, 

 328-360; tail, 217-233; tarsus, 77-83 mm.; females, length, 495-559; 

 wing, 315-358; tail, 210-235; tarsus, 75-87 mm. 



This species seems to have its nearest relative in S. davi.soni Hume," 

 but difl'ers in being smaller, and in having the bend of the wing mot- 

 tled, instead of uniform white or yellowish white; in S. davlsoni the 

 tibial plumes are barred, but in the ncAv species they are spotted. 



The dimensions of S. davm/m'., as given by Hume, are: Length, 

 559-609; wing, 356-394; tail, from vent, 254-280; tarsus, 79-97 mm.* 



Dr. Abbott found the new species "common in the jungle, and 

 especially on the edges of clearings. Not at all shy, and easily called 

 up.'' Snakes, centipedes, lizards, and remains of crabs were found 

 in tiie stomachs of the specimens collected. 



All (jf the specimens, 15 in number, were obtained on Simalur. 



A bird of this genus may occur on Tuangku, where "the peculiar 

 cry of Spilornis was never heard, but a large hawk was seen once or 

 twice in the forest which may have been Spilornis.''''
