ned to the primary forest, and was
common at both localities listed. Smythies (1960:444) thought it
resided primarily at elevations of 2,000 to 4,000 feet,
occasionally occurring near sea level. This flycatcher seems to
prefer the understory of the forest, where it was observed sitting
on bare limbs and darting out after insects.

This flycatcher was seen only in primary forest, on the above
dates. The birds collected appear to provide the only definitive
records for North Borneo (_cf._ Smythies, 1960:445), although Mary
Norman observed the species once at Quoin Cocoa Estate on an
unspecified date (Smythies, 1963:281).

This was the most common "blue" flycatcher at Kalabakan. It was
recorded at Quoin Hill only by Garcia. The record by Smythies
(1963:281) seems open to question as no specimen was preserved.

The "blue" flycatcher of the Quoin Hill area was observed several
times in the primary forest and primary forest edge. On July 14,
1962, I saw a male and a female of _M. venusta_ bathing in a
shallow stream in the deep forest. They fluttered their wings in
the water and then flew to a nearby fallen log and preened f
