Fig. 3. Rostro-carinate Implement. Rather less than 

 natural size. Stuart Creek. See Type No. 5, p. 212. 



Fig. 3a. Side view of above showing the rostro-carinal ridge 

 and beak in section. 



Plate XIII. 



The figures on this plate illustrate various forms of pointed, 

 or "beaked/' Implements with scraper features. 



Fig. 1. Strongly "beaked" Scraper with uniform large chip- 

 pings making an almost circular Implement. Rather under 

 natural size. Macumba. See Type No. 10, p. 213. [Compare 

 i., pi. 2; also xn., (a), figs. 25-28.] 



Fig. 2. A Tasmanian Pointed Implement introduced for 

 comparison. The stone is a thick, dark-red jasper, with white 

 blotches and shining lustre. A conchoidal fracture, in one plane, 

 forms the under-side, while the upper has been roughly shaped 

 into a subhemispherical outline. A main feature is the develop- 

 ment of a prominent point at the distal end, bordered by a 

 double scraper, one on either side of the point. On the right-hand 

 side, a secondary point is also developed bordered by two hollow 

 scrapers. The proximal end is thick. The similarity of this 

 Implement to many of the tableland forms is self-evident. The 

 figure is a trifle under natural size. The specimen was obtained 

 in Tasmania by the writer and is in his possession. 



Fig. 3. A flat Implement worked into points and concave 

 (hollow) scrapers. The stone is a very fine-grained Desert Sand- 

 stone. The under-side is formed by a smooth conchoidal curve 

 that covers half the surface, the remaining portion being chipped 

 to reduce the face to a common level. The chief point occurs at 

 the distal end with two carefully-chipped concave scrapers on 

 either side. If the Implement be revolved through an arc of 

 90°, from right to left, another point, bordered by finely-worked 

 scrapers, forms a feature similar to the first described. The whole 

 edge of the Implement has been worked. The upper-surface has 

 been chipped, apparently to reduce the thickness. The stone is 

 of a reddish colour and has a distinct glaze. Natural size. 

 Stuart Creek. 



Fig. 4. A carefully-worked Implement consisting of points, 

 claw, and scrapers. The under-side is formed by a single, convex, 

 conchoidal fracture, that was formed by flaking from a previously- 

 made, striking platform. At the distal end is a well-shaped 

 point, bordered on either side by concave scrapers. With the 

 exception of the proximal end, the whole edge has been worked, 

 developing special features, including a "claw" on the left side, 

 near the base of the tool. The upper-surface has been shaped, 

 mainly, by two concave, smooth fractures. The stone is a very 

 fine-grained variety of Desert Sandstone, is highly coloured — 

 almost black on the worked edge. Patinal glaze strongly marked. 

 It has the appearance of great age. Natural size. Stuart Creek. 



Plate XIV. 



Fig. 1. A roughly -triangular Pointed Implement, with con- 

 cave scrapers of varying sizes. Shows much fine chipping. 

 Natural size. Stuart Creek. See Type No. 3, p. 212. 



Fig. 2. An Ovately-shaped Implement with serrated edge, 

 probably used for both cutting and scraping. Rather under 

 natural size. Stuart Creek. See Tvpe No. 11, p. 214. [Compare 

 v., fig. 42; also xn., (a), figs. 12, 14.]
