262 A NATURALIST'S WANDERINGS 



narrow in front, the sides straight and gradually diverging to the parietal 

 eminences, which are situated near the posterior border of the parietal 

 bones. The differences in the broadening out of the cranium from the 

 anterior frontal to the parietal regions in the two skulls is well seen by 

 comparing the relation of the minimum and maximum frontal breadths 

 of each with their respective maximum breadth, this latter being taken 

 as 100. In the skull belonging to the skeleton, which we will designate 

 as No. 1, the indices are 67 '4, 79'2, and 100 ; in the other skull, which we 

 will call No. 2, they are 64, 772, and 100. The glabellar region is flat and 

 smooth, corresponding to outline No. of Broca in skull No. 1, and to 

 No. l.*in skull No. 2; superciliary lidges are entirely absent. The fore- 

 head rises somewhat vertically to the level of the frontal eminences 

 (which are not prominent), and then slopes backwards and upwards till 

 it attains its maximum, which is situated in the parietal region. Viewed 

 from the norma frontalis, the arch of the top of the cranium is markedly 

 flat, giving the Stephanie region a somewhat angular appearance. In the 

 parieto-oocipital region the contour of the cranium falls with a moderate 

 curve towards the foramen magnum. The general surface of the cranium 

 is smooth, and the muscular ridges are little pronounced. The mastoid 

 processes are feebly developed. 



The sutures are very simple in No. 2, but somewhat more complicated 

 in No. 1, though still simple ; thofe in the former being represented by 

 Broca's outlines of complication of sutures No. 2 for the fronto-parietal, 

 and No. 3 for the parieto-oocipital suture, the latter by No. 2 — 3 for the 

 fronto-parietal, and No. 4 for the parieto-occipital. "Wormian bones are 

 not present in either skull. In No. 2 the sutures are more open than in 

 No. 1,* in which the coronal and sagittal sutures are approaching 

 obliteration. 



With regard to the projection of the zygomatic arches, in relation to 

 the contour of the bi-stephanic region, No. 2 is slightly phaenozygous, 

 but in No. 1 the arches are not visible, bi-zygo-stephanic index being 

 87'7 in No. 1, and 913 in No. 2. In my paper on the Cranial Characters 

 of the Natives of Timor-)aut, 1 1 showed that skulls in which this index is 

 90 and upwards are phaenozygous ; these Kubu skulls are therefore on 

 the border-line between the two conditions. The inion is fully developed 

 in both skulls, being represented by Broca's outline No. 1. 



The average horizontal circumference of the two skulls is 490 mm., 10 

 mm. less than the average circumference of the heads of the five living 

 females measured by Mr. Forbes. 



Facial portion. — The nasal bones have a very characteristic shape; they 

 are not moderately prominent in respect to the plane of the face, and 

 form a gentle curve from above downwards, being intermediate in curve 

 between Broca's outlines Nos. 1 and 2. The nasal aperture differs in the 

 two skulls: in No. 1 it is longer and slightly narrower than in No. 2, the 

 index of the former being 50, while that of the latter is 56'8, which places 

 No. 1, in the middle of the mesorhine group (48 — 53), and No. 2 well 

 within the platyrhine (above 53). The inferior border is nearly straight 

 transversly, and is fairly well defined. The nasal spine of No. 1 is 

 represented by Broca's outline No. 2, and in skull No. 2 by the outline of 

 No. 1. 



The orbits are somewhat more rounded, in No. 1 than in No. 2, the 

 orbital index of the former being 89 2 and of the latter 80'1. The 

 margins of the orbits are thin and sharply defined.
