Part of the left parietal and frontal bones (Register-No. 38309, British Museum), 
showing thickening of the frontal and a similar low form of forehead to that in the 
calvarium (No. 38308). This portion shows part of a hole of about an inch in diameter, 
where so much of the bone appears to have been depressed or beveled off prior to inter- 
ment. Two portions of left parietal bone, one with parts of the squamous and coronal 
sutures (Register-No. 38316, British Museum), the other with a parietal foramen 
(Register-No. 38317). 
In a block of breccia from the same recess and depth was found the following portion 
of the lower jaw of an adult (Register No. 38335, British Museum). 
The horizontal part of the left ramus with the symphysis retaining the first true 
molar, m 1, and the sockets of the two incisors, canine, two bicuspids and second true 
molar, of the same side : the socket of the third true molar, if it ever existed, has been 
obliterated, consequent on early loss of that tooth. 
The sockets of the incisors are relatively smaller, especially in fore-and-aft diameter, 
than those in a female Australian ; they more nearly accord in size with those of the 
European ; the sockets of the premolars or bicuspids are simple, without the ridged 
indication of the grooved beginning of a division of the fang, as in the Australian. The 
socket of the second premolar is placed obliquely, and is divided, as usual, by a thicker 
septum from that of the first, than is the septum between any of the antecedent sockets. 
The first true molar is worn flat down to the stumps, sloping slightly from within out- 
ward and downward ; a small part of the enamel is preserved on the inner ends, the 
friction, as usual, in human lower molars being greatest towards the outer margin of the 
crown ; a smooth field of dentine composes the chief part of the grinding-surface : this 
molar is implanted, as usual, by two fangs, subcompressed from before backward. 
The socket of the second true molar shows a similar insertion of that tooth, and that 
the anterior fang was grooved longitudinally at its fore part, and was larger than the 
posterior fang. 
The fore part of the base of the coronoid process, which is preserved, shows the ridge 
extending to the back part of the last alveolar, and marking the boundary of the inser- 
tion of the temporal muscle. External to the ridge is the broad and shallow groove 
continued, contracting, along the outside of the hinder alveoli and bounded externally 
by the ‘ external oblique ridge ’ continued from the front margin of the coronoid pro- 
cess. The ridge subsides before reaching the ‘mental foramen’ here situated beneath 
the second premolar. 
Beneath the foramen is a well-marked ridge for the origin of the ‘ depressor anguli 
oris’ and for the insertion of the ‘ platysma myoides.’ The symphysis developes ante- 
riorly a well-marked ‘mental process’ or chin, the contour exemplifying a higher type 
than in the Australian; but the chin is of less vertical extent than in average-sized 
male jaws of Indo-european races. 
Above the tubercular ridge at the back of the symphysis giving attachment to the 
genio-hyo-glossi muscles, is an unusually deep depression with a small foramen at the
