16 BOOMERANGS FROM N.S.W. AND QUEENSLAND, 



free space beyond the retumi of the loops is occupied by sigmoidal 

 figures of two incisions each, and a central gently lunate outline. 



The length is two feet three and a quarter inches; the breadth 

 two inches; and the weight nine ounces. It is from the same 

 locality and collection as the two previous weapons. 



The two succeeding boomerangs (Figs. 1 or 7) have disconnected 

 loops, or rather half-loops placed back to back and touching in 

 pairs. Cross bars are also present, but dififer in the two weapons. 

 In both the loops are formed of six undulating grooves, producing 

 a figure along one margin of each weapon, then returning on 

 itself, and proceeding along the other margin, leaving a wide space 

 in the middle line. In Fig. 1 there are seven of these half -loops, 

 and in Fig. 7 six. In Fig. 1 the apical half-loops are turned in 

 opposite directions, and one is smaller than the other. That at 

 one of the apices is cut off by a single incised transverse line, 

 and is followed by two half loops abutting against one another, 

 and again divided off near the middle of the weapons by another 

 transverse incised line. Two further half-loops repeat the same 

 order, separated by the third transverse incised line from the first 

 large half-loop referred to as occupying one of the apical portions 

 of the boomerang. The arrangement in Fig. 7 is practically the 

 same, but in consequence of the penultimate apical half-loops 

 being nearly of a size, the sculpture is almost bilaterally 

 symmetrical. The cross-bars are only two, wide quadrangular 

 spaces, vertically incised with close grooves. The interspaces 

 between the two parts of each half-loop are occupied in the 

 middle line of the weapon with a zig-zag figure of two incised 

 lines, the angles of the zig-zag either continuous or broken. In 

 Fig. 7 there is only one such figure, but in Fig. 1 three of the half- 

 loops are infilled with an additional series of a single incision. 

 Again in Fig. 7 an additional zig-zag line is represented immediately 

 along the central convex edge of the weapon.
