In any othcr parts of the country it was ncvcr obscrvcd. 



The colour of the upper parts of tho body is rather variable as scen by a series 

 in the Royal Natural History Museum in Stockholm. In old birds the underparts of 

 the body are very dark slaty black vvithout traces of the white bars which are very con- 

 spicuous in young birds. 



Immature specimens have the primaries dark rufous brown with orange brown 

 shafts to the primaries and secondaries, and the back is olive brown and not greyish 

 as stated by Elliot. In old birds the primaries and the secondaries are dusky black 

 with an olivaceous brown shade on the outer webs. The shafts of the primaries and 

 secondaries are black. The white spöts above and below the eye seems to be larger and 

 rnore prominent in the Hat Sanuk specimen than in specimens from the southern parts 

 of the Malay Peninsula.

The first time I observed this Swallow-Shrike was near Chieng Sen, where a large 

 flock had settled down in a bamboo-clump on the bank of the Mekong river. From their 

 resting place they now and then made aerial evolutions, though always returing to the 

 same place again where the whole party was perching quite close to each other like 

 some kind of weaver-birds. 



At the neighbourhood of Koh Lak thej^ were also obtained, though apparently 

 more rare here than up in the Northern parts of the country. Here they haunted open 

 sandy plains, resting on the branches of dead trees or on telegraph wires. At the environs 

 of Bangkok I ne ver observed them, but from that locality they have been recorded by 

 Williamson and other authors.
