58 CORVID®. 
This Magpie has the central tail-feathers narrower than in 
C. varians and more abruptly spatulate at their ends. 
Distribution. Central and South Burma, Siam and N. Malay 
Peninsula. Harington obtained it as tar North as Monywa and 
Pymmana on the Chindwin, and it extends East into West Central 
Siam. Wickham obtained it as far North as the foot of Mt. Vic- 
toria in the Chin Hills. 
Nidification. Similar to that of C. varians, though the nests 
appear to be smaller and neater. The eggs are small replicas of 
those of that bird and measure 23:0x18-0 mm.  Harington 
obtained its eggs in May. 
Habits. Differ in no way from those of the Black Racket-tailed 
Magpie, but it seeins to keep more exclusively to bambvo-jungle 
and scrub. It is a bird of the dry zone, and will not be found in 
those parts of Burma where the rainfall is very heavy.

Genus PLATYSMURUS Reich., 1760. 
The genus Platysmurus contains two species, one of which is 
resident in Tenasserim whilst the other inhabits Borneo. In 
many ways this genus connects the typical Magpies and the 
typical Jays. 
The bill is very much curved and shorter than the head and the 
bristles covering the nostrils are numerous and stiff but short. 
The feathers of the crown of the head are very harsh. The tail 
is of no great length but well graduated. Thesexes are alike and 
the young resemble the adults.

Glaucopis leucopterus Temm., Pl. Col., No. 265 (1824) (Sumatra). 
Platysmurus leucopterus. Blanf. & Oates, 1, p. 37. 
Vernacular names. None recorded. 
Description. The whole plumage black; the terminal halves of 
the larger upper wing-coverts and a large patch on the exterior 
webs of some of the outer secondaries white; the forehead 
crested and the feathers stiff. 
In some specimens the smaller wing-coverts are narrowly mar- 
gined with white, and this probably means immaturity. 
Colours of sofc parts. Bill, legs, feet and claws black; irides 
lake-red to crimson. (Davison.) 
Measurements. Length about 400 to 410 mm.; wing about 199 
to 200 mm.; tail about 200 to 220 mm.; tarsus 35 to 38 mm ; 
culmen about 35 mm.
