398 DISSEMURUS LOPHORHINUS. 



the Opate hills came on a flock which seemed to be moving from one part of the forest to another ; they 

 were making their way along from tree to tree beneath a vast precipice, and uttering a loud whistle, which 

 one bird took up from the other as they disappeared from my gaze through the dense foliage. It has an 

 inveterate dislike of Owls, particularly the "Devil-bird," which is a fellow inhabitant of the gloomy wilds; 

 and whenever it espies one of these birds which has neglected to seek a proper place of concealment, it attacks 

 it with loud cries, and is soon joined by a host of small birds (Bulbuls, &c), which soon drive the luckless 

 Ulaina to a distant part of the forest. 



Nidification. — This species breeds in the south of Ceylon in the beginning of April. I have seen the 

 young just able to fly in the Opate forests at the end of this month, but I have not succeeded in getting any 

 information concerning its nest or eggs. 



The figure in the Plate accompanying this article is that of a very large male example shot in the 

 Kottowe forest, having an exceptionally fine tail.
