_=Arachnothera flavigaster=_ (Eyton): Greater Yellow-eared
Spiderhunter.--_Specimens_, 9: Cocoa Research Station: [Female] imm.,

brood patch, largest ova 2 mm., November 27, 1962, MCT 3330; [Male],

ADG 66; [Female], April 27, 1963, ADG 67.

This species was met with only at Quoin Hill, where it was common
around the abaca and wild bananas. The primary diet seemed to be
pollen, nectar, and spiders. I found it easy to differentiate from
the next species in the field (see below).

_=Arachnothera chrysogenys harrissoni=_ Deignan: Lesser Yellow-eared
Spiderhunter.--_Specimens_, 4: Cocoa Research Station: [Female], 23.5
gm., August 21, 1962, MCT 2788; [Male], April 27, 1963, ADG 68; [Male],
April 30, 1963, ADG 92; [Male], May 27, 1963, ADG 113.

I observed this species at Quoin Hill only once, but Garcia took
three specimens at the same locality. He labels his specimens as
taken in primary forest. I never saw the species there and took my
one specimen in the abaca, where the bird was eating spiders,
nectar, and pollen. The chief characters distinguishing this
species from _A. flavigaster_ were the tuft of yellow feathers on
the side of the head and the narrow eye ring in _A. chrysogenys_.
