On the other hand, they much resemble, in appearance and mode of life, descriptions of many of the primitive Malayans who have intermixed with Negritoes. Of these the Kubus of Sumatra are an instance,[129] and of the Jakuns of Johore, who are believed to be of Negrito origin, but much interbred with Malays. Mr H. Lake[130] writes: "The true Jakun is of short stature, 5 feet 2 inches is a fair average height. They are much darker in colour than the Malay, and, as a rule, not so well set up. The hair, which in the pure Negrito curls closely, is here in most cases simply wavy, or even straight. They live in small communities, and subsist miserably on fruits, roots, etc. They seldom remain many weeks in the same spot, but wander from place to place, living under scanty shelters built on rickety poles at a considerable height from the ground. It is not uncommon to find a dozen in company, with a tame monkey or two, cats and dogs, living in perfect harmony under the same roof." We may therefore consider the Shom Pe[.n] to be the aborigines of the group, who, although everywhere else either exterminated or absorbed by settlers from outside, have in Great Nicobar found a refuge in the forest depths, and by long-standing hostility to the intruders, arising from some unknown cause, have preserved to a great extent their natural traits and existence, although somewhat degenerated, both on account of the less favourable circumstances in which they live and of the interbreeding that the smallness of their numbers compels. Although the Shom Pe[.n] are by measurement as tall in the average as the coast people, to the eye they appear smaller, and they are less robust, with lean though bony figures (average chest measurements, 35.2 inches), sinewy rather than muscular. Fourteen measurements of adult males gave a maximum height of 67-3/4 inches, a minimum of 62-1/8 inches, and an average height of 64 inches. Of eight women measured, the tallest was 65-1/4 inches in height, and the smallest 57-3/8 inches, while the average stature of that number was found to be 60.8 inches. The colour of the skin is a dark muddy-brown or bronze (several shades deeper than the coast natives), but it is liable to slight variation, and is generally a little paler in the women and girls, who resemble far more distinctly the coarse Malayan type than the men do. The hair of the head is very luxuriant, and of all varieties between wavy and curly, but is not crisp or frizzly to any degree. No hair grows on the face, or on the body, save about the armpits, etc. The outline of the face is an oblong rectangle, and the forehead is somewhat retreating, but occasionally high and rounded, though narrow; the supraciliary arch is prominent, but the eyebrows are light. The eyes, with black pupils, are both oblique and horizontal, and when the latter, are often accompanied by the Mongolian fold, which occurs most frequently among the women.
