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.)
