58 CORVTDJE. 



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 far North us Monywa and 

 Pymmana on the Chimlwin, and it extends East into West Central 

 Siam. Wickham obtained it as far Nortli 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*0 x 18*0 mm. Harington 

 obtained its eggs in May. 



Habits. Differ in no way from those of the Black Backet-tailed 

 Magpie, but it seems to keep more exclusively to bamboo-jungle 

 and scrub. It is a bird of the dry zone, and uill 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. The sexes are alike and 

 the young resemble the adults. 



(38) Platysmurus leucopterus. 

 THE WHITE-WINGED JAY. 



Glaucopis leucopterus Temm., PI. Col., No. 265 (1824) (Sumatra). 

 PUitysmurns leucopterus. Blanf. & Gates, i, 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 leathers 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 190 

 to 200 mm. ; tail about 200 to 220 mm. ; tarsus 35 to 38 mm ; 

 culmen about 35 mm.
