48 GYLDENSTOLPE, BIBDS COLLECTED BY THE SWEDISH ZOOLOGICAL EXPEDITION TO SIAM. 



During an excursion near Sakerat in Eastern Siarn I got a fine male specimen, 

 which shows that this species also extends inore to the West. 



This species is closely allied to the preceding one, which on the contrary 

 was found in more northerly parts of Siarn.

90. Chrysophlegma flavinucha Gould. — This speoies was only observed in] 

 the dry forests of Northern Siarn, but here it was very common and often heard 

 or seen.

91. lyngipicus canicapillus Blytii. — This small Woodpecker was seen both 

 singly, in pairs and in flocks in the dry forests which covered such an extended area 

 round Den Chai and Pak Pan. It was mostly observed in high trees and was 

 not at all shy — ■ at least when in flocks. 



I ne ver heard its note but very often it indicated its presence by a rather 

 noisy tapping on the dry trees, long before I caught sight of the bird itself. In the 

 evergreen forests I ne ver observed it, nor in the eastern parts of the conntry so it 

 seems not to extend far to the east; perhaps not beyond the Menam valley with i 

 its open conntry covered with rice-fields. ,

92. Micropternus phaioceps phaioceps Blyth. — Especially common round 

 both Den Chai and Pak Pan. 1 also observed it on the Korat plateau but here it 

 seemed to be rather rare. In the evergreen forests it never occurred but was found 

 now and again in bamboojungles. It was as a rule very silent and sometimes very | 

 difficult to catch sight of amongst the confusion of branches. i 



All my specimens have a very unpleasant smell and their plumage is smeared 

 with some substance coming from the tree-ants nests. Tliey generally feed on ants 

 and lay their eggs in holes made by the large tree-ants nests. On the tail-feathers
