patterns which had been engraved on the frontal bone, and which 
may be arranged conveniently in five groups. 
Group 1 was the most simple, and consisted of straight incised 
lines directed diagonally, and continued into each other at their 
ends so as to provide a chevron or herring-bone-like pattern. This 
mode of ornamentation was present in four crania. In three of 
these it extended across the frontal bone, from one temporal curved 
line to that on the opposite side. In one specimen three horizontal 
parallel lines had been cut from one curved line to the other ; the 
lowest line w T as 15 mm. below the middle one, and the highest 
line was 7 mm. above it (fig. 2). Each interval contained several 
diagonal lines, which passed alternately from left to right and from 
right to left, and formed a complete chevron pattern. Immediately 
above each supraorbital ridge an incised line had been made, which 
accentuated the projection of the ridge, and the adjoining part of 
the frontal bone had been scraped and polished. 
In a second specimen three similar parallel lines, at almost equal 
distances apart, had been cut between the two temporal curved 
lines ; in the upper interval twenty-nine incised lines were directed 
from right to left, in the lower interval seventeen lines passed 
from left to right, and to produce the chevron pattern both sets 
of lines were required. A chevron figure, which consisted of 
two pairs of diagonals, had also been scratched on the upper 
part of the frontal bone (fig. 3). 
In a third specimen two parallel lines had been cut across the 
frontal bone, and in the interval a complete chevron pattern, 
consisting of fourteen diagonal lines, had been incised (fig. 4). 
Above the upper parallel line the arc of a circle had been cut, and 
its concavity contained an incised figure, which consisted of two 
triangular limbs, diverging upwards and outwards from a centre in 
the middle of the frontal bone. Each limb showed two pairs of 
incised lines, which met at their upper ends and enclosed an un- 
paired central line. The two limbs converged below, and by their 
union formed an enlarged chevron pattern. In the interval 
between the two limbs two circles, one within the other, had been 
cut. This figure was transitional to the radiated designs in group 
2. In the fourth specimen no parallel lines were cut across the 
frontal, but about midway between the two temporal ridges a
