Khas, a term originally meaning "Men," but now applied by the Siamese and Laotians to all the wild tribes of the border ranges; in this sense it answers to the Moi of the Annamese and the Pemmg of the Cambojans. But it is a word of too general application to have any ethnological value. There are Khas tribes everywhere in Indo-China, and the term enters into the composition of an immense number of tribal names, not only in this region, but also in South China and North-East India.
