Among the Primates, the Agile Gibbon (Hylobates agilis) I 
believe occurs, keing replaced in the mountains by H. lar. The 
Crab-eating Macaque is found, generally not far from running water, 
and also the Pig-tailed Macaque (M. nemestrinus) of the same olive- 
brown colour as the last, but with a tail of some 7-8 in. only; it has 
not yet been observed at any considerable elevation. 
The Northern limit of the Langur already referred to on 
page 33 seems to be N. Lat. 13° 20’ and it is generally distributed 
in the plains and the highest mountains. The animals obtained in the 
plains appeared smaller and darker in colour. North af Lat. 13° 20’ 
I have never seen it, but its place is taken by a griggled black species, 
with silvery grey whiskers so long that the ears are almost concealed. 
I have not yet been able to identify this species, but it was very 
common in the Me Pachi valley and | had considerable opportu- 
nities for observing it during this year. The very young ones are 
light reddish fawn, with blue eyes, and the dark colour of the adult 
first appears on the crown of the head. The young were, on llth 
April, about 7 in. long and were able to leave their mother and play 
among the bamboos. This and the previous species have a large 
vocabulary, ranging from a loud hoarse indescribable bark to a nasal 
«Kum on,” which is repeated with emphasis if the young do not 
“come on,” but they differ from the former species in that they 
frequently hoot at night. The young are never still, and while their 
elders are having a midday siesta in the denser tree tops, the young 
play in the lower branches, and on one occasion an adult came down 
to stop the uproar below. Both these species will endeavour to mictu- 
rate on passers-by, whether out of contempt or for other reasons [ 
cannot say, but it is not done through fear in most cases. 
Frequently the Langurs and Macaques were feeding together 
and at such times the Macaques discovered me before the Langurs ; 
more frequently a squirrel gave me away, starting a squittering note 
of alarm.

being particularly common; anda Jungle Cat (Felis chaus) was shot 
close to camp while devouring a hare, and which it showed no inclina- 
tion to give up or leave. This is a long legged and short tailed cat—
