Dicrurus aeneus malayensis (Blyth): Bronzed Drongo.—Specimen, 1: 12 mi. N Kalabakan: ♀, October 20, 1962, MCT 3104.
This drongo was seen only once, when a flock of three to five was feeding late one evening in a clearing where the trees had been cut down the day before.
Dicrurus paradiseus brachyphorus (Bonaparte): Large Racket-tailed Drongo.—Specimens, 5: Cocoa Research Station: ♀ immature, 58.2 gm., August 4, 1962, MCT 2727; ♀, 65.1 gm., August 20, 1962, MCT 2786; ♂, December 1, 1962, MCT 3413. 12 mi. N Kalabakan: ♀, October 20, 1962, MCT 3102. Kalabakan: ♂, November 18, 1962, MCT 3303.
I seldom saw this species in the cocoa at Quoin Hill. Twelve miles north of Kalabakan it was common in tree tops 150 feet up, foraging in the upper canopy.
Oriolus xanthonotus consobrinus Ramsay: Malaysian Black-headed Oriole.—Specimens, 9: Cocoa Research Station: ♂ imm., 41.8 gm., July 22, 1962, MCT 2639; ♀, 40.7 gm., July 23, 1962, MCT 2644; ♂ testis 1 × 1 mm., 48.2 gm., July 24, 1962, MCT 2653; ♀ imm., 36.3 gm., July 28, 1962, MCT 2681; ♂ imm., 40.4 gm., August 25, 1962, MCT 2804; ♂, September 26, 1962; MCT 2962; ♂, November 29, 1962, MCT 3381; ♀, December 2, 1962, MCT 3426. 12 mi. N Kalabakan: ♂, October 28, 1962, MCT 3180.
This oriole was common in the cocoa and in secondary forest surrounding the cocoa at Quoin Hill.
Platylophus galericulatus coronatus (Raffles): Crested Jay.—Specimens, 4: 12 mi. N Kalabakan: ♀, October 17, 1962, MCT 3068; ♀, October 21, 1962, MCT 3116; ♂, October 21, 1962, MCT 3117; ♂, October 21, 1962, MCT 3118.
This jay was observed several times at the forest camp at Kalabakan. The bird utters a metallic chattering noise much like that of other jays, except for the metallic quality. I observed it also in moss forest 5.5 miles north of Tenom.
Comparison of my specimens with series in the U. S. National Museum and the American Museum of Natural History indicates wide variation within this species in Borneo. The specimens vary considerably in depth of brown, some approaching P. g. lemprieri and others P. g. coronatus. Because of this wide variation I have not recognized the subspecies lemprieri and place all specimens from Borneo under coronatus.
Platysmurus leucopterus aterrimus (Temminck): Black Crested Magpie.—Specimens, 4: Cocoa Research Station: ♀ brood patch refeathering, 181.6 gm., July 21, 1962, MCT 2628; ♀ imm., 143.4 gm., July 21, 1962, MCT 2629; ♀, September 4, 1962, MCT 2865; ♂, 178.0 gm., September 6, 1962, MCT 2880.
