Jehebr; Temongoh , Upper Perak (Plate XVIII, figs, 1, 2, 3), 
This tribe is represented by four skulls, two of which are associated with 
imperfect sets of the long bones. The specimens were procured in the 
immediate vicinity of Temongoh, where No. 5 was found by one of us (N.A.) 
This skull was said by the Malays, who showed me its position, to be that of 
a Jehehr headman named Padang, whose body had been cast into the river by 
his followers and had been brought ashore by the current at the village bathing 
place. The three remaining specimens were collected during my four days* 
stay at Temongoh by an old Malay woman. 
Skulls. Two of the skulls (Nos. 5 and 6) appear to be male and two to 
be female, the sexual characters being fairly well marked. The male specimens, 
judging from the condition of the sutures, represent individuals in the prime 
of life ; while both female specimens show signs of considerable age, 
Norma vertkalis. The outlines of Nos. 4, 5, and 7 is a broad and regular 
ovoid, the development of the central part of the parietal region not being 
excessive ; but No. 6 is oval, and somewhat squared in the frontal region. 
The mean cephalic index of the four specimens is 76' I, the extremes 
being 7I'2 and yS'O. The slope of the post-parietal region is gradual, in 
No. 6 remarkably so. In all four specimens the vault of the cranium has a 
tendency to be roof-shaped ; this is very marked in No. 6 and least conspicuous 
in No. 5. In No. 7 the bregma is protuberant. The side walls of the cranium 
are nearly vertical except in No. 5, in which they are decidedly convex. The 
circular or oval depression in the post-parietal region, so often noted in our 
collection, is present, or has its place taken by a localized flattening in every 
specimen representing this tribe. The parietal arc is considerably longer than 
the frontal. 
Nortna lateralis . Prognathism is more marked than the gnathic index 
would seem to show, especially in No. 7. The nasal bones are very flat and
