 the cackling and clambering round about her. 



(129) Garrulax leucolophus belangeri. 

 THE BURMESE WHITE-CRESTED LAUGHING-THRUSH. 



Garrulax belattf/eri Less., Trsite d'Orn., p. 648 (1831); Blanf. & 

 Gates, i, p. 79. 



Vernacular names. Wa-youn-hnet, Way-oung-hnet-goung byu 

 (Burmese). 



Description. Differs from the preceding in having the white of 

 the breast running into the abdomen instead of being sharply 

 defined by the rufous colour. The colour of the upper parts is a 

 light ferruginous- rather than an olive-brown. 



Colours of soft parts as in leucolophus. 



Measurements. A rather smaller bird than the last, with a wing 

 of about 125 to 130 mm. 



Distribution. Yunnan, North and South Shan States, Aunam, 

 Lower Chin and Kachin Hills, Pegu and Tenasserim. 



Nidification. Similar to that of the last bird, twelve eggs 

 averaging 28-3 x 22*7 mm. 



Habits differ in no way from those of the last or the next bird. 



(130) Garrulax leucolophus diardi. 

 THK SIAMESE WHITE-CRESTED LAUGHIXG-THRUSH. 



Turdus diardi Less., Traite" d'Orn., p. 408 (1831) (Siam). 

 Garrulax diardi. Blanf. & Gates, i, p. 79. 



Vernacular names. None recorded. 



Description. Differs from the other two races by the grey of 

 the crest merging into the rufous back instead of contrasting 

 therewith. The whole of the abdomen is white. 



Colours of soft parts as in the other races. 



Measurements. The largest of the three races with a wing 

 between 135 and 140 mm. 



Distribution. Extreme South Yunnan, Siam, Cambodia, Annain, 

 Cochin China, rarely extending into South-East Tenasserim, and 

 then in a somewhat intermediate form approaching belangeri. 

 The specimens in the British Museum from the Shan States and 

 Annam labelled "diardi" should all be referred to the last race, 

 belangeri. 



Nidification. Similar to that of the other races. Twelve eggs 

 average 27'4 x 22-4 mm., but a larger series would probablv 

 average bigger. 



Habits. Like those of the other races but this form appears to 

 be found well into the plains.
