These are the Semang or Pangan, the Sakai or Jakun, and the Malays.
The mistake of speaking of the Sakai tribes as practically identical with the Semang or Pangan has very frequently been made, but as a matter of fact the two races are absolutely distinct from one another.
It has also been customary to include the Sakai in the category of Malayan races, but this too is undoubtedly incorrect.
The Sakai still inhabit in greatest numbers the country which forms the interior of Pahang, the Plus and Kinta districts of Perak, and the valley of Nenggiri in Kelantan.
An examination of their language seems to indicate that, it belongs to the Mon-Khmer group of languages, and the anthropological information forthcoming concerning the Sakai points to the conclusion that they show a greater affinity to the people of the Mon-Khmer races than to the Malayan stock.
