19U0.] MAMMALS OF SIAM AND THE MALAY PENINSULA. 321 



identified, labelled " Siam ; " it measured, head and body 24| in. 

 (or 622 mm.); tail 31^ in. (800 mm.). Mr. A. Balfour, Chief 

 Engineer of the Siamese Navy, kindly gave me three skulls of 

 Semnopithecii which he had shot near Ratburee, Siam ; unfortunately 

 I never had a chance of comparing them with skulls of known 

 species, but they are still (or ought to be) in the Museum at 

 Bangkok.

In Penang I got numerous specimens from natives, who said 

 they had caught them in the hill forests ; I also got two individuals 

 in Kedab. In the Museum at Taiping there are many specimens 

 from Barut, Perak ; these resemble in head-markings and colour 

 Penang specimens of the variety javanicus. In the Museum at 

 Kuala Bumpor are two specimens, probably caught in Selangor. 

 Mr. Oldfield Thomas (P. Z. S. 1886, p. 73) has recorded a spe- 

 cimen collected at " Salanga, Junkceylon," by Mr. J. Darling, and 

 one from Malacca collected by Mr. Davison. Ridley records this 

 animal from Pahang (J. S. B. R. A. S. 1894, no. 25, p. 57) and 

 from Singapore (Mamm. Malay Pen. p. 26). 1 There are three 

 Siamese specimens in the Museum at Bangkok. 



Colour (of a Siamese specimen). Head, neck, lower parts and 

 inner side of the limbs, lower parts of the fore limbs, and hands 

 and feet very pale silvery grey, almost white. Remainder of fur 

 light rufous brown, intermiugled with many silver hairs. A bright 

 reddish-brown vertebral line, which gets narrower anteriorly and 

 terminates on the forehead (and does not join the ear-patches or 

 the eyes as it does in eight specimens obtained in Penang). The 

 patch round each ear is light reddish brown. 



Size (of Siamese specimen noted above). d • Head and body 

 14| in. (or 375 mm.) ; tail (without end hair) j in. (or 20 mm.). 



Habits. In captivity these animals will live on bananas, mangoes, 

 bread and milk, and live small birds, which they are singularly 

 adroit at catching. At night, if left to themselves, they depart 

 from their usual deliberate ways and climb about with con- 

 siderable speed and activity. At one time I used to sleep in a 

 hammock slung in a veranda close to a cage of Kongkangs, and 

 when lying awake on moonlight nights had good opportunities of 

 observing their habits. They could squeeze through the bars of the 

 cage (though I never made out how they got their bodies through 

 such narrow opeuings as they were) and roam about ; usually they 

 were back in the cage by daylight, sometimes they remained absent 



1 Three of the specimens on which M. Alphonse Milne-Edwards founded 

 Nycticebus, cinereus (Nouvelles Archives du Museum, iii. 1867, p. 9, pi. iii.) 

 were " pris aux environs de Bangkok."
