784 SIR WILLIAM TURNER, THE CRANIOLOGY OF THE NATIVES OF BORNEO, 



D had a left epipteric ; the alisphenoid articulated freely with the parietal. The mastoids, 

 inion and curved lines were moderate. C had a smooth surface on the left jugal process 

 which had probably articulated with the transverse part of the atlas ; there was no 3rd 

 condyl. 



The mean cephalic index of the five Murut skulls was 73 "9, and if the mesaticephalic 

 D be excluded, only 72 '9 ; in both instances the mean index was dolichocephalic. The 

 mean vertical index in four specimens was 75, metriocephalic. The mean glabello- 

 occipital length was 179*2 mm. ; the mean greatest breadth 132*4 mm. ; the mean 

 basi-bregmatic height 134*2 mm. As regards the relations of the breadth to the height 

 of the cranium, in only one skull did the breadth exceed the height, and the mean 

 breadth-height index of the four specimens was 100*97 ; the crania belonged therefore 

 to the group to which I have extended the name hypsistenocephalic,* to include skulls 

 in which the index exceeds 100. 



The three male crania ranged in internal capacity from 1300 c.c. to 1430 c.c, and 

 the mean was 1370 c.c. ; in the female E the capacity was 1330 c.c, whilst in D, the sex 

 of which was doubtful, it was 1430 c.c.t 



Dusuns. Table I. Plate I. 



The name Dusun is given to a tribe in Borneo which occupies the interior of the 

 island from its northern end to as far south as the Dutch territory. Their country is to 

 the north and east of the Muruts, and the Sulus intervene between them and the eastern 

 sea-coast. They are well built, muscular and active. The skin is a light, clear brown, 

 fairer than the Malays of the coast ; the hair is black, and is worn by the men hanging 

 down over the shoulders ; the eyes also are black. Burbidge says that some have well-cut 

 features, though the Mongolian type of face prevails ; the nose is flattened at the root 

 and the nostrils are wide. The teeth are filed and blackened, and the skin is tattooed. 

 The usual stature is 5 feet 4 or 6 inches. The Dusuns are by some authorities considered 

 to possess a strain of Chinese blood, and are less given to head hunting than some of the 

 other tribes. By some authorities the name Ida'an is applied to the Dusuns. 



Three skulls presented by Dr Adamson were labelled Dusun, and of these F was 

 further designated Tegahas, a tribe which lives in the hilly country in the interior ; 

 G was from the Kinarut district in north-west Borneo ; H, Dusun Dyak, Si Labandang, 

 of Ulu Papar, near the source of the river Papar. They were male adults ; G and H 

 retained the lower jaw, and in G a large part of the two parietals and of the occipital 

 squama had been apparently sliced otf by a sharp weapon. The skulls were not 

 uniform in character. H was much larger and more massive than the others ; and

 cephalic and hypsistenocephalic. 



t The cranial capacity in this as in my previous memoirs was taken by the method employed and described 

 in my Challenger Report, Zoology, part xxix. p. 9, 1884, the accuracy of which has been confirmed since that time by 

 repeated investigations.
