MAMMALS OK B0RNH:0. 1 I 



as the middle of the forearm and of tlie lower leo' while, 

 continuous with that of the chin and tliix)at. Tail hoary 

 grey like the back throughout, only rather darker above than 

 below, owing to the larger proportion of black as compared 

 with white hairs there present. 



Skull light and delicate. Nasal bones long, thin ; profile 

 quite straight and continuous with the line of the forehead, 

 an arrangement very different from the peculiar aquiline nasal 

 outline of S. femoralis. Nasal opening oval, its breadth about 

 two-thirds its height, instead of three-fourths as in the allied 

 species. Bulke low, opaque. Teeth as usual. 



Dimensions of the type, an adult male, preserved in skin: 



Head and body (c.) 520 millim.; tail 670; hind foot 154; 

 heel to tip of hallux 123; length of eyebrows 25-28; length of 

 crest-hairs (c.) 40. 



Skull. — Greatest length (gnathion to occiput) 91 millim. 

 basal length (basion to gnathion) 61 ; zygomatic breadth, 68; 

 nasal opening, height 15.2, breadth ro.o; nasal length 10, 

 greatest breadth 10; interorbital breadth 8.0; distance from 

 outer edge of one orbit to that of the other 55.5; height of 

 orbit, 23; breadth across the face, including external walls of 

 orbits, 62; intertemporal constriction, 46; brain-case breadth 

 54, height from basilar suture to bregma (junction of sagittal 

 and frontal sutures) 47; palate, length 30, breadth outside 

 ml 30, inside mj^ 18.8; combined length of upper pre- 

 molars and molars 2 6, of molars only 17.6. This hand- 

 some monkey is perhaps my finest discovery amongst the 

 mammals. The type was shot at a place called Niah in the 

 Raram district. I have since procured several specimens in 

 different parts of the country, but although it is often seen in 

 the low country I think we must consider it to be a mountain 

 species which leaves the mountains at certain times in search 

 of fruit. It ascends Mount Dulit to the height of 4000-ft., 

 but is more common at 2000-ft. It frequents the salt-springs 

 which are common in the inteiior, churning up the mud, and 

 it is at these salt-springs that the Punans procure numbers of 

 specimens with the blowpipe and poisoned arrows. From 

 this monkey the Bezoar stones are obtained, being found either 

 in the gall bladder or near it. The noise that this animal 

 makes is loud and distinct — Gagah, gagah. The young re- 

 sembles the colour of the adults, and are exceedingly pretty 

 little things, but they won't li\'e long in confinement and 

 would never bear a voyage to Englanil, as they suffer severely 

 from sea-sickness. The Kayan name is ' Bangat.'
