Color—­Ranges from light brown, with strong saffron undertone, to very dark brown or bronze.

Eyes—­Black to hazel brown.  “Malayan” fold in large majority.

Hair—­Coarse, straight and black.  A few individuals possess curly or wavy hair.

Nose—­Jenks gives no statement, but his photos show the root of the nose to be rather high; the bridge appears to be broad and straight, although in some individuals it tends toward concave.

Very different results were obtained by Kroeber [32] from the group of Igorot exhibited in San Francisco in 1906.  His figures may possibly be accounted for by the fact that about one third of the party came from Alap near the southern end of the Bontoc area, also, as he has suggested, by the preponderance of very young men.  The figures for this group are as follows:

From these descriptive sheets it is obvious that each tribe is made up of very heterogeneous elements, and each overlaps the other to a considerable extent; however, the number of individuals measured is sufficiently great for us to draw certain general conclusions from the averages of each group.
