STATURE: Two men are tall, 6 medium and the rest short, 6 being below 1.5 m., of whom 2 are under 18 years old; the median is 1.572 (5 ft. 2 in.). The women over 23 average 14 cm. shorter than the men; this is a large difference, as it is usually 10 — 12 cm., as in our Sarawak figures.]
VI. Iban (or Sea Dayaks) Group
Fifty-six IBAN men were measured by us.
HEAD-FORM: The cephalic index forms a gradual series, the median being 83, and therefore shows brachycephaly. The head is usually hypsicephalic, but 1 is platycephalic as regards breadth-height, 2 are mesocephalic both in length-height and breadth-height, 5 are mesocephalic in length-height and 3 in breadth-height. Thirteen are noted as round, 7 as ovoid, 4 as oval, several had broad parietal and narrow frontal regions producing a pyriform norma verticalis.
FACE: The form is noted as pentagonal in 10, oval in 5, broad oval in 4, the narrowness of the jaw producing the pentagonal shape. The majority are chaniaeprosopic, but 1 is leptoprosopic in total facial and upper facial indices, and 7 are leptoprosopic in upper facial index. The forehead is generally full or slightly bulging, but may be straight and vertical; 3 are noted as being sloped. The cheek-bones are prominent in 20, and moderately so in 24. The lips are moderately full. The chin is small and moderately prominent. NOSE: Sixteen are mesorhine, 21 platyrhine, and 19 hyper-platyrhine. The profile is concave in 23, straight in 18 and nearly so in 4; the root is more or less high in 19, more or less depressed in 20, in most cases it is broad or moderately so; the base is straight in 24, reflected in 25, deflected in 3; the alae are wide in 8, moderate in 6, small in 9; the nostrils are oval in 10, transversely oval in 8, round in 13, wide in 9. EYES: The aperture is narrow in 13, medium in 18, wide in 3; it is straight with no fold in 10 and with a slight fold in 11, slightly oblique with no fold in 10 and with a moderate fold in 21. The majority are normal as regards the eyelashes, but 3 have a distinct Mongolian character and 5 have it slightly. The colour is intermediate in 25, dark in 22, light in 5, 4 cases were noted with a bluish margin to the iris. EARS: Type European in 31, European to Negroid in 2, Negroid in 2, orang flattened above in 1; angle slightly prominent in 22, rather more so in 1, prominent in 8, more so in 1, very prominent in 1; lobule distended in 10 and perforated in 5, very small in 1, small in 13, being adherent in 4, rather small in 1, medium in 10, 1 being adherent, 2 perforated, and 1 doubtful; descending helix absent in 2, infolded less than 2 mm. in 23, 2 — 4 mm. in 13; Darwin's point an infolded tip in 1, an inrolled knob in 2, absent in the rest; tragus under 3 mm. in 11, being double in 1, slightly larger in 1, 3 — 5 mm. in 25, being double in 3, 5 — 7 mm. in 1; anti-tragus absent in 4, under 3 mm. in 24, 3 — 5 mm. in 8, 5 — 7 mm. in 1; anti-helix below level of helix in 23, about at the same level in 15.
HAIR: It is straight in 16, wavy in 26, curly in 2, 1 being described as crisp. The colour is rusty black in 26, black in 17, and dark brown in 1. Eight men had a slight amount of hair on the face; the body hair is absent or very scanty, but one had a quantity on his legs.
SKIN: Five are dark warm cinamon, 27 cinamon (6), 5 light cinamon (14), 11 dull fawn (17), 11 light brown (near 17), 5 various shades of a light greenish sepia (light 3 1), 3 a still lighter greenish sepia.
STATURE: One man is tall, 11 are of medium stature, and the remainder short, 2 being under 1.5 In.; the median is 1.585 m. (5 ft. 2 1/2 in.).
Thirteen SIBUYAU men were measured by Mr. Shelford and 1 by us.
HEAD-FORM: All but two are brachycephalic, the median being 83. Mr. Shelford did not measure the radii and so the height indices cannot be given.
