The flora consists of 129 species of angiosperms, i Cycas, 22 ferns, and a few mosses, lichens and fungi, 17 of which are endemic, while a considerable number - not specifically distinct - form local varieties nearly all presenting Indo-Malayan affinities, as do the single Cycas, the ferns and the cryptogams. As to its fauna, the island contains 319 species of animals-54 only being vertebrates-145 of which are endemic. A very remarkable distributional fact in regard to them, and one not yet fully explained, is that a large number show affinity with species in the Austro-Malayan rather than in the Indo-Malayan, their nearer, region.
The distributional area FIG.
In general appearance it is very like some of the pariah dogs of India and Egypt; and, except on distributional grounds, there is no reason for regarding it as specifically distinct from such breeds.
