SLOW LORIS. 



Type locality. Bengal. 



Geogr. Distr. Bengal, Upper Burma, possibly Annam. 



Genl. Char. Head with lines indistinct ; dorsal line disappearing 

 towards crown of head. 



Color. Rufescent gray above, paler beneath ; dorsal stripe broad, 

 deep brown, expanding on the crown where it is rufous including the 

 ears; orbital ring brown. ( Blanf ord). 



This is the larger and possibly more common form of Nyctice- 

 bus found east of the Bay of Bengal. Its distinctness as a separate 

 species, from N. c. cinereus cannot yet be established with certainty, as 

 the material available is not sufficient for definite decisions to be 

 reached. Blanford (1. c.) says that this species is purely nocturnal and 

 arboreal. It feeds on leaves, shoots of trees, insects, bird's eggs and 

 young birds. It is generally silent or utters a feeble crackling sound. 

 If angry, however, and ready to bite it makes a low growl or grunt. 

 In captivity it soon becomes docile and very gentle, but when first 

 captured is apt to be savage.
