chestnut-brown stripe runs down the back from the crown to the 

 loins, but does not expand into a broad patch on the crown. Each 

 eye is surrounded by a dark brown circle, broadest above ; a 

 narrow space in front between the two orbital rings is whitish or 

 white. A small oval patch, including each ear, is also brown. 

 Nose and soles of feet flesh-coloured where naked. 



The other variety is, as a rule, smaller and rufescent grey above, 

 paler below; the dorsal stripe is broader, and often deep rich 

 brown; it usually expands into a broad rufous expanse on the 

 crown, including the ears but not the eyes, which are always 

 surrounded by a brown ring. 



A third form is figured from Tenasserim by Tickell, from whose 

 drawing the accompanying cut is taken. In this, which is pale 

 rufescent, the dorsal stripe simply bifurcates on the forehead, one 

 band running to the circle round each eye. 



This leads to the type known as N. javanicus, in which there are 

 four brown bands running down the head and face from the crown, 

 one to each eye and one to each ear ; the interspaces pale, and those 

 between the eyes white. This variety, or race, is said to be 

 peculiar to Java, and rather smaller in size than the others, and to 

 have almost constantly only two upper incisors. Schlegel, too, 

 states that it has eight lumbar vertebrae instead of six. It is very 

 doubtful, however, if any of these distinctions are constant. 



Dimensions. An adult male from Upper Burma, according to 

 Anderson, measured : head and body 13-2 inches long, tail O75, fore 

 limb and foot 7'2, hind limb 9. Jerdon gives a greater length, 14-5 

 to 16 inches. All these are taken from the large northern variety. 

 A Tenasserim adult male, measured by Tickell, was 12-75 inches 

 long. Two adult skulls measure 2-5 and 2'65 inches in extreme 

 length, 2-2 and 2-3 in basal length, 1-7 and 1-8 broad across the 

 zygomatic arches. A Javanese skull is only 2-15, 1*85, and 1-55 

 inches in the three dimensions. 



Distribution. Throughout the countries east of the Bay of 

 Bengal Burma, Malacca, Siam, and the islands of Sumatra, Java, 

 and Borneo. Common in Assam, Sylhet, &c., and extending west 

 to the neighbourhood of Eangpur and Dacca, but not found in the 

 Himalayas. 



Habits. Purely nocturnal and arboreal. This animal feeds on 

 leaves and shoots of trees, fruits, insects, birds' eggs, and young 

 birds. It has been observed by Tickell to raise itself on its hind 

 legs and throw itself upon an insect. As a rule it is silent, or 

 only utters a feeble crackling sound, but when angry and about 

 to bite it emits a tolerably loud growl or grunt. When captured, 

 it is at first apt to be savage and prone to bite, but soon becomes 

 very gentle and docile. 



Tickell, from whose MS. the above notes are chiefly derived, 

 says : " This animal is tolerably common in the Tenasserim 

 provinces and Arakan, but, being strictly nocturnal in its habits, is 

 seldom seen. It inhabits the densest forests, and never by choice 

 leaves the trees. Its movements are slow, but it climbs readily,
