narrow in front, the sides straiglit and gradually diverging to the pnrietnl 

 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 witli their respective maximum breadth, this latter l>eing taken 

 as lUO. In the skull belonging to the skeleton, which wc will designate 

 as No. 1, the indices are 67'4, 79"2, and 100; in the other skull, wliich wt. 

 will call No. 2, they are 64, 77*2, and 100. The glabellar region is flat and 

 smooth, corresponding to outline No. of Eroca in skitll No. 1, and to 

 No. 1. 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 sloi>es backwards and upwards till 

 it attains its maximum, w^hich is situated in the parietal region. Viewed 

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

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

 parietooccipital region the contour of the cranium falls with a moderate 

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

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

 processes are feebly developed. 



The sutures are very simple in No. 2, but somew*hat more complicated 

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

 Broca^s outlines of complication of sutures No. 2 for the fronto-parieta!, 

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

 frontoparietal, and No. 4 for the p'arieto-occipital. Wormian bones arc 

 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 phsenozj'gous, 

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

 " 87*7 in No. 1, and 91-3 in No. 2. In my paper on the Cranial Characters 

 of the Natives of Timor-Iaut,t I showed that skulls in which this index is 

 90 and upwards are ph^enozygous; these Kubu skulls are therefore on 

 the border-line betwx^en the tVo conditions. The inion is fully developed 

 in lx;th skulls, being represented by Broca's outline No. 1. 



The averaire horizontal circumference of the two skulls is 410 mm.. 10 



* ■ ■ . 



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



females measured by Mr. Forbes. 



Facial portion,— l^h^ 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 



l>etwcen Broca's outlines Nos. 1 and 2. The nasal aperture differs in the 



two skulls; in No. I it is longer and slightly narrower than in No. 2, the 



index of the foi-mer being 50, while that of the latter is 5G*8, which places 



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



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



transversly, and is fairly well detined. 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. I than in No. 2, the 

 orbital index of the former being 89 2 and of the latter SO'l. The 

 margins of the orbits are thin and sharply defined.
