20 GYLDENSTOLPE, BIRDS COLLECTED BY THE SWEDISH ZOOLOGICxiL EXPEDITION TO SIAM. 



6. Garrulus leucotis Hume. — In the dry forests of Northern Siarn tliis Jay 

 was not rare, though by no means common and it was more of ten heard than seen. 



Like other jays this species is also a very shy bird and the best metod to get 

 it was to wait near a junglefire, where I could be pretty sure to get sight of several 

 jays. In the Central and Eastern parts of the country it seems to be lacking or 

 very rare; I at least ne ver observed it in any locahty visited:

7. Garrulax diardi Less. — The Siamese white-crested Laughing Trush was 

 one of the most common birds met with in secondary- and brushjungles över the 

 whole of Siam. They are rather shy but when I approached them and they caught 

 sight of me they all struck up their curious garroulous laughter and for a second 

 or so they gazed at the intrader. Suddenly their cries ceased and then they went 

 away jumping from one twig to another spreading their pretty white crests. Then 

 they again commenoed their concert which finished as suddenly as it had begun. 

 As a rule the Laughing Trushes were in company with some specimens of the Racket- 

 tailed Drongos {Dissemurus paradisens L.)

8. Garrulax moniliger Hodgs. — The Necklaced Laughing Trush was observed 

 on different occasions mixed up in the flocks of Garrulax diardi Less. but always 

 only limited numbers. It seemed to be more common to the north and I could 

 never iclentify this bird either in Central or Eastern Siam. 



This species is closely allied to Garrulax pectoralis Gould. but differs from 

 that bird in wanting the black cheek-stripe and in having the primary-coverts of 

 the same colour as the other wing-coverts. 



Both Garrulax pectoralis Gould. and Garrulax moniliger Hodgs. have been 

 recorded from the Burmese countries though the former type is more northern than 

 the last-mentioned.
