Artamides sumatrensis Sharpe, Cat. Birds Brit. Mus. (1879), 4, 12 (part). Graucalus sumatrensis difficilis Hartert, Novit. Zool. (1895), 2, 470. Artamides difficilis Sharpe, Hand-List (1901), 3, 287. Artamides dificilis McGregor and Worcester, Hand-List (1906), 76 (error).

Balabac (Everett); Calamianes (Bourns & Worcester); Palawan (Steere, Everett, Lempriere, Whitehead, Steere Exp., Bourns & Worcester, Celestino, White).

Adult male.--Except wings and tail, nearly uniform pale gray, palest on uropygium and crissum, much lighter gray than in A. striatus or A. mindorensis; no black on forehead, lores, and chin. A male from Palawan measures: Wing, 158; tail, 115; culmen from base, 29; bill from nostril, 21; tarsus, 25.

Adult female.--General color pale gray like the male; rump and upper tail-coverts white, barred with black; black bars on under parts narrower than the white spaces, and under tail-coverts with only one or two bars on each feather. An immature female from Palawan measures: Wing, 145; tail, 108; culmen from base, 25; bill from nostril, 18; tarsus, 25.

Young.--The young male is barred like the young female and the young of both sexes have white fringes on the rectrices, remiges, and wing-coverts.

"Fairly common; frequents high trees. Three males average: Length, 282; wing, 155; tail, 121; culmen, 32; tarsus, 23; middle toe with claw, 26. A female, length, 279; wing, 150; tail, 114; culmen, 30; tarsus, 25; middle toe with claw, 26. Iris pale yellow; bill, legs, feet, and nails black." (Bourns and Worcester MS.)

446. ARTAMIDES GUILLEMARDI Salvadori.

GUILLEMARD'S ARTAMIDES.

Artamides pollens Guillemard, Proc. Zool. Soc. (1885), 258. Artamides guillemardi Salvadori, Ibis (1886), 153; Sharpe, Hand-List (1901), 3, 288; McGregor and Worcester, Hand-List (1906), 76.

Bongao (Everett); Lapac (Guillemard); Sibutu (Everett); Sulu (Platen, Bourns & Worcester); Tawi Tawi (Bourns & Worcester).

Male.--Under parts uniform gray; feathers covering nostrils, lores, and space in front of eye deep black. Tail, about 144.

Female.--Entire upper and under parts uniform gray as in A. mindorensis. Wing, 170; tail, 142.

In naming this species Salvadori compares it with A. schistaceus from the Sula Islands and does not state in what way it differs from the previously described Philippine species, but the diagnoses given above are sufficient to distinguish it.

"Fairly common; frequents high trees in the forest. Three males average: Length, 307; wing, 172; tail, 137; culmen, 34; tarsus, 26; middle toe with claw, 30. Four females, length, 316; wing, 168; tail, 137; culmen, 35; tarsus, 25; middle toe with claw, 28. Iris very dark brown; legs, feet, nails, and bill black." (Bourns and Worcester MS.)
