even in the Pacific Islands. There are two sections of White 
Owls, which may be distinguished as Barn-Owls and Grass-

land. Both the known species of Grass-Owls are easily recog- 
nised by their uniform brown upper surface, instead of having 
vermiculations on the back, like the Barn-Owls, and they are

while the second, 5 . Candida, is found in India and China, 
the Philippines, North Australia, and re-occurs in the Fiji 
Islands.
