Tills Ma£^pie Las the central tail-feathers narrower than in 

 C. varians and mure abruptly spatulate at their ends. 



Distribution. Central and South Burma, Siam and N. Malay 

 Peninsula. Harington obtained it as far Xorth as Monywa and 

 Pyminana on the Cliindwin, and it extends East into AVest Central 

 Siam. Wickham obtained it as far North as the foot of Mt. Tie- 

 toria in the Cliin Hills. 



Nidification. Similar to that of C. variaxs, though the nests 

 appear to be smaller and neater. Tlie 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 Racket-tailed 

 IMagpie, but it seems to keep more exclusively to bamb'io-jungle 

 and scrub. It is a bird of the dry zone, and v\ill not be found in 

 tliose parts of Burma where the rainfall is very 'heavy. 



G-eniis PLATYSMURUS Reich., 1760. 



The genus Platijsmunis contains two species, one of whicli is 

 resident in Tena^serim 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 shoit. 

 The feathers of the crown of the head are very harsh. The tail 

 is of no great length tnit well graduated. The sexes are alike and 

 the youi'ig resemble the adidts.
