“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.)

“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.)
