N. GYLDENSTOLPE, MAMMALS COLLECTED IN SIAM. 5 



The German Engineer mr. E. Eisenhofer had a speci- 

 men of this species kept in captivity at his bungalow at 

 Bång Hue Horn, and it was said to have been captured in the 

 bill forests north of this place. The specimen, which was a 

 nearly fullgrown male, was very tame and amusing. 



3. Presbytis crepuscula Elliot. — Elliot: Ann. & 

 mag. Nat. Hist. Ser. 8. vol. IV. 1909 p. 270. — During my 

 stay at the Meh Lem river I once made an excursion to the 

 neighbouring limestone mountains, and here I observed a 

 party of about 15 specimens of this rare monkey. 



After several fruitless efforts I at last succeeded in shoot- 

 ing a fine nearly fullgrown male. The herd generally kept 

 very high upp in the trees, and the animals were very shy. 

 The native hunter who accompanied me told me that these 

 monkeys were only seldom seen, or shot, and he also said that 

 they only occur at a considerable height, never descending 

 into the lower valleys. 



My specimen is exactly of the same colour as the type 

 specimen described by Elliot from Mooleyit in British Burma 

 according to the statement by mr. G. Dollman who kindly 

 has examined my specimen.
