28 GYLDENSTOLPE, BIEDS COLLECTED BY THE SWEDISH ZOOLOGICAL EXPEDITION TO SIAM. 



ant both in tlie dry forests and in secondary- and bamboojungles. I never observ- 

 ed it in tlie real primeval evergreen forests thougli I several times noticed it in 

 old, nearly overgrown clearings found here and there around the few villages, as 

 for instance at Bång Hue Horn. The Ashy Drongo seems chiefly to prefer the bam- 

 boojungles and in these it was the commonest species among the Dicrurida?. A female 

 shot near the town of Muang Pré shows much greater dimensions than another female 

 from Bång Hue Hom as seen by the measures given below.

31. Chaptia aenea Vieill. — The Bronzed Drongo occurred both in the Eastern 

 districts and in Northern Siam, and probably also in tlie central parts of the coun- 

 try, though I did not shoot any of them there. It was especially common round 

 the small village of Non Luum in Eastern Siam and was there often seen in flocks 

 together witli some other members of the family.

32. Chibia hottentotta L. — During the whole duration of the Expedition I 

 only shot one male specimen of the Hair-crested Drongo at Pak Pan on the 19th 

 of February but at this place it was rather common and mixed up in the flocks of 

 the other Drongos. 



On the Korat plateau I did not get any, but I believe it is also to be found 

 there.

33. Dissemurus paradiseus L. - This beautiful bird was very common every- 

 where on suitable localities and I think I can say with absolute veracity that I 

 observed Racket-tailed Drongos every day with the exception of the time I spent 

 at Bangkok. The best way to get this species, as well as the other members to 

 the family, was to wait close to a jungle fire. As soon as such a fire began, the
