_=Muscicapa rufigastra rufigastra=_ Raffles: Mangrove Blue
Flycatcher.--_Specimen_, 1: Tuaran: [Male], December 14, 1963, SCFC 33.

_=Muscicapa dumetoria mulleri=_ Blyth: Orange-breasted
Flycatcher.--_Specimens_, 5: Cocoa Research Station: [Male], 11.8 gm.,

testis 3 x 2 mm., November 11, 1962, MCT 3246; [Male] testis 5 x 4 mm.,
November 28, 1962, MCT 3384. 5.5 mi. SW Tenom: [Male], December 25,
1962, MCT 3531.

This species was seen only in the understory of primary forest. On
November 10, I watched a male and female feeding about three feet
above the ground in the undergrowth. They sat on small vines and
plants and darted out after insects. I never observed this species
more than 20 feet above the ground.

_=Muscicapa narcissina=_ Temminck: Black and Yellow
Flycatcher.--_Specimens_, 2: Cocoa Research Station: [Female], November
27, 1962, MCT 3331. 5.5 mi. SW Tenom: [Male], December 20, 1962, MCT
3484.

The two specimens were taken in nets in the primary forest. They
cannot presently be assigned with certainty to subspecies.

This abundant species at Quoin Hill and Kalabakan was chiefly an

On July 31, I observed this species singing at Quoin Hill. One sang
with its mouth closed and sounded much farther away than it
actually was. The song has seven notes on a descending scale. Birds
observed on September 27 were in heavy molt and one specimen lacked
