Nycticebus tenasserimensis. 



Nycticebus tardigradus Tenasserim variety. Blanf., Faun. Brit. 

 Ind., 1888-91, pp. 45, 46, fig. 12. 



TENASSERIM SLOW LORIS. 



Type locality. Tenasserim. 



Genl. Char. Dorsal stripe bifurcating on the forehead and encir- 

 cling the eyes. 



Color. "Pale rufescent." 



Major Tickell appears to be the only one who has seen this animal, 

 and Blanford reproduces Tickell's drawing in his work on the Fauna of 

 British India. The manner in which the dorsal stripe bifurcates on the 

 forehead, each stripe passing forward and encircling the eyes, is cer- 

 tainly peculiar and unlike that of any other member of the genus. 

 Before its distinctness can be established satisfactorily, Tenasserim 

 specimens must be procured and properly compared with examples from 

 other parts of India. Blanford quoting from Tickell's notes states, that 

 this animal is purely nocturnal and arboreal, and feeds on leaves and 

 shoots of trees, fruits, bird's eggs, and young birds. It has been 

 observed to raise itself on its hind legs and throw itself upon an insect. 

 As a rule it is silent or only utters a feeble, croaking sound, but when 

 angry and about to bite it emits a tolerably loud grunt or growl. When 

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

 becomes very gentle and docile. 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, 

 and grasps with great tenacity. When placed on the ground it can pro- 

 ceed if frightened, in a wavering kind of trot, the limbs placed at right 

 angles. It sleeps rolled up in a ball, its head and hands buried between 

 its thighs, and wakes up at the dusk of evening to commence its noc- 

 turnal rambles. The female bears but one young at a time.
