brownish gray, tinged with olive yellow; “bill brownish black; feet 
dark fleshy brown.” 
Doctor Abbott obtained the following eight specimens: 
Adult male, No. 170916, U.S.N.M.; Pulo Riabu, August 18, 1899. 
Adult male, No. 170917, U.S.N.M.; Pulo Riabu, August 18, 1899. 
“Tris brownish red; bill dark horn brown, paler beneath; feet fleshy 
brown.” 
Adult male, No. 171000, U.S.N.M.; Pulo Mobur, August 25, 1899. 
“Tris red; bill black; feet dark fleshy brown.” 
Adult male, No. 170938, U.S.N.M.; Pulo Siantan, August 20, 1899. 
“Feet fleshy brown.” 
Adult male, No. 170940, U.S.N.M.; Pulo Siantan, August 21, 1899. 
Adult male (type), No. 170941, U.S.N.M.; Pulo Siantan, August 
24, 1899. ‘Bill brownish black; feet dark fleshy brown.” 
Adult male, No. 170943, U.S.N.M.; Pulo Siantan, September 10, 
1899. 
Adult female, No. 170939, U.S.N.M.;.Pulo Siantan, August 21, 
1899. 
There is comparatively little individual color variation in the 
series, such as there is consisting chiefly in the more deeply ochraceous 
tinge on the abdomen, and the more golden hue of the olive yellow 
crissum. The worn summer plumage is considerably paler than the 
freshly molted feathers. 
In all but one bird the molt is more or less in evidence. In four 
(Nos. 170938, 170940, 170941, and 171000, U.S.N.M.), taken, August 
20 to 25, it is from about two-thirds to three-fourths completed; 
and many feathers of the old plumage remain; in one (No. 170943, 
U.S.N.M.), taken, September 10, it is about five-sixths advanced; 
in two others (Nos. 170916 and 170917), taken, August 18, it is, to 
external appearances, complete except for the wing-and tail-quills, 
but some of the contour feathers are still partly in their sheaths. 
One female (No. 170939), taken, August 21, has apparently not yet 
begun to molt. 
Doctor Abbott says that this species was common in the scrubby 
jungle on Pulo Siantan. Measurements are as below:
