Distribution—The Grey Gentle-Lemur inhabits the eastern 
side of the Betsileo province of Madagascar. 
Habits—The “‘ Bokombouli,” as the natives name this animal, 
is the smallest of any of the True Lemurs. It is nocturnal, and 
lives, according to the Rev. G. A. Shaw, among the bamboos in 
the higher-level forests of the island. Its lower incisors are 
used as scrapers, and nearly all its teeth are serrated and very 
effective in cutting off the bamboo shoots, on which it feeds. 
To enable it to grasp smooth surfaces, such as the stems of the 
bamboo and other trees it frequents, it possesses a broad pad 
under each great toe.
