.""beak" at the apex. The base is thick and unworked. It is 

 deeply stained to a dark-brown colour. The included sand- 

 grains are glistening with a feebly developed glaze. Loc, 

 Stuart Creek (pi. xii., fig. 1). [For claw-shaped examples 

 from the Red Crag, see ix., figs. 35, 36.] 



2. An Implement with the shape of an irregular isosceles 

 triangle. Size, 4§ in. x 3 in. Material, a fine-grained sand- 

 stone. Under-side exhibits conchoidal fracture in one large 

 curve. Upper-side has been formed by striking off two 

 conchoidal flakes, leaving a dorsal ridge which is non- 

 symmetrical. Secondary chippings on two edges, directed to 

 a point, the termination of which is broken off. Basal portion 

 thick and unworked. Colour, dark brown; patina, strong. 

 Loc., Stuart Creek (pi. xviii.). 



3. A pointed (beaked) Implement with nearly parallel 

 sides. Size, 3§ in. x 2^ in. A very fine-grained siliceous sand- 

 stone, brecciated. Under-side formed by a convex conchoidal 

 fracture. Upper-side, chipped to an irregular cutting edge 

 all around, terminating at apex in a distinct "beak." The 

 ridge on the upper-side is sunken and cavernous through 

 defective silicifi cation. Colour, lightish-brown on under-side, 

 darker on upper, and especially dark on the chipped edge. 

 Patina well developed. Loc, Stuart Creek (pi. xiv., fig. 1). 



4. Lozenge-shaped Implement. Size, 5 in. x 4 in. In 

 composition, a typical example of Desert Sandstone, possess- 

 ing a good conchoidal fracture. Under-side is formed in one 

 smooth surface with large percussion bulb. Upper-side is 

 ridged inequilaterally, and a less defined ridge is seen towards 

 the right-hand edge. On the left a portion of the original 

 surface of the stone is preserved. The base is short and thick. 

 Except at the base, very fine secondary chippings occur around 

 the edge. At the apex — opposed to the base — a very pro- 

 minent point, or beak, is formed, by the creation of a notch 

 ion one side. Colour, faintly reddish, darkest on the natural 

 surface. Glaze, slight. Loc, Macumba (pi. xvi.). 



5. Roughly -triangular and poinded, Implement of a 

 ■distinctly rostro-carinate type. Size, 3^ in. x 2 in. Stone, 

 fine-grained (porcellanite). Thick. Under-side smooth, show- 

 ing conchoidal fracture. Near the centre of the under-side 

 is an oval depression, left by a flake that has been removed 

 by solation. Upper-side is shaped by primary (coarse) and 

 secondary (fine) chippings. Apex, pointed at termination of 

 dorsal ridge. Basal end, thick. Reddish-brown in colour, 

 lighter at the chipped edges. Glaze, moderate. Loc, Stuart 

 Creek (pi. xii., figs. 3 and 3a J. [Compare this implement with 

 the following: ix., figs. 1-7; xi., pis. 23-27.]
