narrow in front, the sides straight and gradually diverging to the y>arietal 

 cmlneijces, whicli are situated ncjir the i>osterior border of tlie parietal 

 l>ones. The differences in the broadcnimg out of the cranium from the 

 anterior frontal to the parietal rep:iona in the two skuILs i& well seen by 

 comttaring the relation of the ininimum and maximum frontal breadtha 

 of each with their re«}-KK'tive maximiun hreadtb, this latter Ixurig taken 

 as loo. In the skull Ixjlonj^ing to the skeleton, which we will designate 

 as Ko. 1, the indices are 67 4, 79 2, and 100; in the other skull, which we 

 will call No. 2, they are 64, 77'2, and lOiJ. The glal>ellar region is flat and 

 Bmooth, corresijoiiding to outline No. 0 of Briiea iii skull No. 1, and to 

 No. 1. in skull No. 2; superciliary lidges are entirely absent. The fore- 

 head risers somewhat vertically to the level of tlie fioutal eminences 

 (which are not prominent), and then sloj>es liackwards and upwards till 

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

 from the normn frovtalts, the arch of the top of the cranium is markedly 

 flat, giving the Stephanie region a soraowhat angular ai>j>earance. In the 

 parictflKkccipital region the contour of the cranium falls with a inwlerate 

 curve toward.^ the foramen magnum. The genei-al surface of the cranium 

 is smooth, and the mnscnlar ridge& are little pronounced. The mastoid 

 processes are feebly develojied. 



The sutures are very simjilc in No. 2, hut somewhat more complicated 

 in No. 1, though still simple; thoge in the former being representetl by 

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

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

 fronto-parietftl, and No. 4 for the parieto-oceipitaJ. Wormian bones are 

 rot present in either skull. In No. 2 the sutures are more open than in 

 No. 1/ in wlych the coronal and sagittal sutures are approaching 

 obliteration. 



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

 the contotir of the bi~atephanic region, No. 2 is slightly phasnozygous, 

 but in No. I 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-laut,t I showed'that skulls in which this index is 

 90 and ujjwartk are ph^nozygoue ; 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 skuUs is 490 mm., 10 

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

 females measured by Mr. Forbes. 



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

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

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

 between Broca*s outlines Nos. 1 and 2. The nasal aperture ditfers in the 

 two skulls: in No. 1 it is longer and shghtly narrower than in No. % the 

 index of the former Ijeing 50, wliile that of the latter is 5C'8, which places 

 No. 1. in tho middle of the mesorhine group (4^—53), and No. 2 well 

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

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

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

 No. 1. 



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

 orbital index of the fonner being 89'2 and of the latter SOI, The 

 mai^ias of the orbits are thin and sharply defined,
