e with virtually no markings and
a pale yellow color, unlike that of the adults.

_=Orthotomus sericeus sericeus=_ Temminck: Red-headed
Tailorbird.--_Specimens_, 1: Cocoa Research Station: [Female] with large
ovum, 10.8 gm., August 11, 1962, MCT 2770.

The bird was uncommon at the research station. The one specimen was
from the cocoa. I saw two others in secondary growth on the edge of
the forest. Possibly this species, like the preceding one, was
approaching full breeding activity.

_=Orthotomus sepium borneonensis=_ Salvadori: Ashy
Tailorbird.--_Specimens_, 8: Cocoa Research Station: [Female] vascular
brood patch, oviduct enlarged with one possible collapsed follicle, 7.8
gm., August 22, 1962, MCT 2797; [Female] imm., 8.0 gm., August 28, 1962,
MCT 2829; [Male], 8.8 gm., September 10, 1962, MCT 2896; [Male], 8.5
gm., September 10, 1962, MCT 2897; [Male] testis 5 x 3 mm., 8.5 gm.,
September 11, 1962, MCT 2901; [Female] largest ova 3 mm., 8.5 gm.,
September 11, 1962, MCT 2902. Tiger Estate: [Female], October 11, 1962,
MCT 3000. 5.5 mi. SW Tenom: [Female], December 20, 1962, MCT 3486.

This was the most common tailorbird in the Quoin Hill area.
Indications were that the species was also breeding (see _O.
sericeus_). Besides the above localities, I observed it 12 miles
north of Kalabakan. A male was heard singing on September 11, 1962;
the song was simple and on an ascending scale. The specimen taken
near Tenom was growing new tail feathers.
