674. ANTHREPTES CAGAYANENSIS Mearns.

CAGAYAN SULU SUNBIRD.

Anthreptes cagayanensis Mearns, Proc. Biol. Soc. Wash. (1905), 18, 6; Proc. U. S. Nat. Mus. (1909), 36, 445; McGregor and Worcester, Hand-List (1906), 100.

Tal-lu-gus-lú-gus, Moros of Cagayan Sulu.

Cagayan Sulu (Mearns).

"This is a slight insular form, most closely related to Anthreptes wiglesworthi (Hartert), from Sulu, P. I., from which it differs in being decidedly yellower below; the sides of the head are more reddish; the greater wing-coverts are narrowly edged with olive instead of broadly with ferruginous; and the bill is smaller. Iris hazel; bill all black; feet greenish olive, with under side of toes yellow." (Mearns.)

"Characters of adult female * * *. Differs from females of Anthreptes griseigularis in the absence of the grayish white chin and throat; from A. chlorogaster in the yellower coloration of the middle under parts and greener upper parts; and from A. malaccensis only in the greater contrast of the canary-yellow of the middle under parts with the green color of the flanks, which in A. cagayanensis are pale oil-green, and in A. malaccensis olive-yellow. I have no female of A. wiglesworthi for comparison. Wing, 65; tail, 47; culmen (chord), 15.5; bill from nostril, 12; tarsus, 15.8." (Mearns.)

Palawan (Everett). Borneo.

"Two males from Borneo have the whole breast olive-yellow like the abdomen and flanks; the pectoral tufts are bright yellow, and therefore very conspicuous; under wing-coverts pale buff, edged with yellow; median wing-coverts, scapulars, sides of head, and ear-coverts very deep maroon-red." (Gadow.)

A male from Mindanao, wing, 63; tail, 38; culmen from base, 18; bill from nostril, 14; tarsus, 16.5.

Subfamily ARACHNOTHERINÆ.
