The remaining point is of chalcedony with the same general form 
and complete secondary chipping as the others, but with a more 
crudely executed stem contracting to a rounded base (W. E. Roth, 
1929, pl. 1 A, a). The length is 5.8 cm. and the maximum width 
2.8 cm. 
IRENG RIVER, RUPUNUNI DISTRICT 
A beautifully chipped, symmetrical projectile point of red jasper 
is reported to have been dredged from the bed of the Ireng River 
near the Good Hope ranch on the northern savanna of the Rupununi 
District. The specimen (pl. 8, a) has a long stem with parallel 
sides and a rounded base. The blade narrows from the base to the 
point, the tip of which is broken off. The margins are straight for 
almost half the distance from the base, where the even edge is broken 
by three serrations on each side. Above the serrated area, there is 
a small expansion producing a slightly bulbous outline, followed by 
contraction to a long, narrow, tapering point. Existing length is 
14 cm., stem length 2.6 cm., stem width 1.4 cm., width at base of 
blade 3.4 cm., distance from base to serrations 4.0 cm., length of ser- 
rated zone 2 cm., width at serrations 2.4 cm., width at upper end of 
serrations 2.0 cm., width at broken tip 0.7 em. 
PALIKUA CREEK, RUPUNUNI DISTRICT 
A point of quite different form is described by W. E. Roth (1929, 
p- 9 and pl. 1 A, c) as coming from Palikiia Creek, a tributary of 
the Rupununi River. It is short and broad, and has shoulder barbs 
and a narrow, straight-sided stem with a straight base. The material 
is said to be a kind of agate. The length is 6.7 cm. and the width 
3.8 cm. 
TABATINGA RIVER, RUPUNUNI DISTRICT 
The only nonceramic site discovered during the 1952 survey of 
the Rupununi savanna was R-4: Tabatinga, a small chipping station 
about 100 meters in from the left bank of the Tabatinga River, some 
500 meters above its junction with the Takutu (fig. 109). Fragments 
of felsite, chert, and quartz were scattered over a small rise in the 
savanna. No well-defined artifacts, either complete or fragmentary, 
were found, and there was no pottery. Two stones show evidence of 
chipping. One (fig. 8, a—c) is an ovoid flake of felsite with a bulb 
of percussion near the center of one long edge and slight retouch 
along the opposite edge. Surfaces measure 4.5 by 2.8 cm., with the 
thickness 1.2 cm. at the center tapering down toward the edges. The 
other (fig. 3, d-/) is a trianguloid flake of chert, smooth on one sur- 
face as a result of the natural concoidal fracture, and chipped on the 
opposite face. The smooth surface has slight use retouch along one
