The Wiiite Owls are almost cosmopolitan, and are foundeven in the Pacific Islands. There are two sections of WhiteOwls, which may be distinguished as Barn-Owls and Grass-Owls, the latter, as their name impHes, frequenting dense grass-.

Both the known species of Grass-Owls are easily recog-nised by their uniform brown upper surface, instead of havingvermiculations on the back, like the Barn-Owls, and they areoften separated by naturalists under a separate genus, Scelo-strix. One of the species, S. capensis, inhabits South Africa,while the second, S. Candida, is found in India and China,the Philippines, North Australia, and re-occurs in the FijiIslands. THE BARN-OWLS.
