Distribution The Slender Loris is common in the lower 
forests of Ceylon and of Southern India, south of the Goda- 
veri river, as well as in those of the Eastern Ghats. 
Habits.—This curious, emaciated-looking, little creature is 
nocturnal, living entirely in trees. It sleeps during the day 
rolled up in a ball, with its head between its legs, grasping its 
perch with its hands. According to Jerdon these animals are 
occasionally brought in large numbers to the Madras market, 
their eyes being a favourite remedy of the Tamil doctors for 
ophthalmic diseases. 
In its movements it is slightly more active than the Slow- 
Loris. Its food consists of succulent leaves, honey, insects, 
birds’ eggs, and small animals.
