| Long heads (dolichocephalic) | 74 and below |
| Medium heads (mesaticephalic) | 75 to 79 |
| Broad or round heads (brachycephalic) | 80 to 90 |
Thus with two exceptions our Negritos are decidedly round headed or brachycephalic. The exceptions are two women (indices 78 and 79), who in other respects are typical. The first had the lowest stature recorded (1266 mm.) and her arm-reach exceeded her stature by 57 mm. Her nose was very broad and flat (index 98), hair kinky, color and other characters those of the pure Negrito. The second woman was without obvious indication of mixed blood, but her nasal index was only 79 or mesorhinian, and this even more than her head form would suggest the probability of some Malay blood. I think we must conclude, then, that the head form of the Negrito, while usually decidedly round, has considerable variation and approaches mesaticephaly.
Topinard’s nomenclature for nasal index is, for the living:
| Broad and flat noses (platyrhinian) | 108 to 87.9 |
| Medium noses (mesorhinian) | 81.4 to 69.3 |
| Thin, high noses (leptorhinian) | 69.4 to 63 |
Those familiar with Topinard’s monumental work will recall the particular importance he gives to the nasal index, and how he shows that it is perhaps the most exact character for classifying races; all white races being leptorhinian, the yellow mesorhinian, and the black or negro races platyrhinian. Indeed the presence of a markedly platyrhinian type of nose may almost be taken as clear proof of negro derivation. The nasal index of Negritos, as would be expected in a race whose outward characters are so obviously negroid, is exceptionally high or platyrhinian. Again the figures for men and women are arranged serially so as to show the mean and variation.
Nasal Index
| Men | Women |
| 84 | 79 |
| 90 | 86 |
| 90 | 90 |
| 91 | 92 |
| 95 | 92 |
| 97 | 92 |
| 97 | 97 |
| 98 | 98 |
| 100 | 98 |
| 109 |
All of these nasal indices, with the sole exception of the woman mentioned above, are below mesorhinian or pronouncedly platyrhinian and negroid.
The shape of the Negrito nose is peculiar and after it has once been carefully observed can be easily recognized. The root is deeply depressed from a smooth and rounding forehead, the bridge is short and low, and the end rounding and bulbous. Sometimes, but not usually, the nostrils are horizontally visible. The apertures of the nostrils are very flat and their direction almost parallel with the plane of the face.
It has been repeatedly asserted that the body color of the Negrito is black, but this is a gross exaggeration. It is a dark brown, several shades darker than the Malay, with a yellowish or saffron “undertone” showing on the less exposed parts of the body. As compared with the lighter colored peoples about him his color is pronounced enough to warrant the appellation of negro which is applied to him, but this term must not be considered as other than a popular description.
