as if the little creatures, loud of good clieer and society, are 

 driven by the gloom and loneliness of the forest to seek each 

 other's company. The bird-population of the forest is not 

 nearly so dense as that of the old cleared land ; the number 

 both of species and of individuals found in the forest is less. 

 If the little birds were evenly scattered through the forest 

 they would be lonely. It is noticeable that certain strictly 

 forest- birds, such as the different species of Turdinus, Alethe, 

 Stiphrornis, and some of Bleda, which live hidden in the 

 undergrowth and feed among the dead leaves, are not often 

 seen in the ejak. They seem to be at home in the forest, 

 and to have no need of companions and noise to cheer 

 their spirits. On the other hand, when a bird of which 

 the more natural home is in the light of clearings goes into 

 the forest, it joins itself to an ejak. Thus Oriolus Icetior, 

 Barbatula duchaillui, and Ixonotus guttatus are birds of the 

 open land ; yet I have seen all of them in the depths of 

 the forest just once, and that in an ejak. 



" One of these companies may easily be followed for a long 

 time, as it moves slowly. When the birds are frightened 

 they scatter and become silent for a few moments ; then 

 they may be heard assembling again further on. Once I 

 observed the same ejak for three days. It passed my camp 

 going east the first day ; I saw it and watched it half a mile 

 or more to the east the second day ; the third day it passed 

 the camp again going westward. The birds in an ejak sleep 

 where night overtakes them." 



I now proceed with the systematic list of the species and 

 remarks thereupon.
