fluctuating grooves, four to six grooves in each range, one group 

 in the middle line, and one on either side, extending from apex to 

 apex, but twice interrupted by cross bars, that differ widely, how- 

 ever, from those figured on preceding weapons. That on one side of 

 the centre consists of two parallel grooves, united by transverse 

 incisions, the other near one of the apices of two such bands, some- 

 what separated from one another, the plain interspace carrying five 

 V-shaped figures placed transversely. On the concave side of the 

 boomerang, and along one part of the edge, is the ever-recurring 

 single zig-zag line, whilst between the fluctuating lines over the 

 general surface, either the same kind of incised sculpture or v- 

 shaped figures parallel to the longer axis of the weapon. 



Length two feet five and a half inches: breadth two and a 

 quarter inches; and weight twelve and a half ounces. This 

 boomerang was received from Normanton, Gulf of Carpentaria, 

 by Mr. N. Hardy, to whom it belongs. 



A very peculiarly ornamented boomerang is represented in Fig. 

 13. Along the convex margin is a series of very deep scallops, 

 reaching transversely to near the middle line of the weapon, and 

 grooved parallel to its longer axis. The middle or centre line is 

 occupied by a single zig-zag, and between this and the concave 

 edge are three deep and wide slightly fluctuating lines of two 

 grooves each. The whole produces a very marked pattern. The 

 apices in this weapon are very sharply pointed. 



Length two feet six inches; width two inches; and weight ten 

 ounces.

 J. C. Cox. 



The last boomerang but two (Fig. 14) bears on each side of the 

 sculptured face long moderately deep festoons, five on either side, 

 and obliquely grooved, but not reaching to either apex. The 

 middle line is occupied b}'' five large ovals, so arranged that each 

 more or less falls into the space left between opposite re-entering 

 angles of the festoons. These are also deeply and obliquely 

 grooved. Clear sj)aces are left at both apices, one containing two
