KNOX, in his captivating account of the island, gives an accurate description of both; the Rilawas, with "no beards, white faces, and long hair on the top of their heads, which parteth and hangeth down like a man's, and which do a deal of mischief to the corn, and are so impudent that they will come into their gardens and eat such fruit as grows there. And the Wanderoos, some as large as our English spaniel dogs, of a darkish grey colour, and black faces with great white beards round from ear to ear, which makes them show just like old men. This sort does but little mischief, keeping in the woods, eating only leaves and buds of trees, but when they are catched they will eat anything."[1] [Footnote 1: KNOX, _Historical Relation of Ceylon, an Island in the East Indies_.--P. i. ch. vi. p. 25. Fol. Lond. 1681. See an account of his captivity in SIR J. EMERSON TENNENT'S _Ceylon_, etc., Vol. II. p. 66 n.] KNOX, whose experience during his long captivity was confined almost exclusively to the hill country around Kandy, spoke in all probability of one large and comparatively powerful species, _Presbytes ursinus_, which inhabits the lofty forests, and which, as well as another of the same group, _P. Thersites_, was, till recently, unknown to European naturalists. The Singhalese word _Ouandura_ has a generic sense, and being in every respect the equivalent fur our own term of "monkey" it necessarily comprehends the low country species, as well as those which inhabit other parts of the island. In point of fact, there are no less than four animals in the island, each of which is entitled to the name of "wanderoo."[1] Each separate species has appropriated to itself a different district of the wooded country, and seldom encroaches on the domain of its neighbours.
