found during the digging of a drainage ditch and reburied. ‘Two 
others were found during excavation of a waterhole and a house post- 
hole. The latter one was broken and the sherds were thrown out. 
The former was complete and reburied by the finder, who said it 
was similar in shape to the one from R-14 but lacked the decorative 
nubbins. This information suggests that isolated burials of the type 
represented by R-14 are relatively numerous in this part of the 
Rupununi savanna. Since there is usually no surface indication, they 
can be found only accidentally. 
CEREMONIAL SITES 
Several writers have mentioned stone alinements near the Ireng 
River in the vicinity of Sites R-16 to R-19. We did not see them, 
nor were they reported to us by loca] residents at the time of our 
survey in the area. No ceramics have been described in association, 
so that the identification of their affiliation is tentative. Similar 
structures occur in the Arua Phase of the Territory of Amapa, Bra- 
zil, and since this Phase has other features that relate to the north, 
the stone alinements in British Guiana have been correlated with its 
movement into the mouth of the Amazon (Meggers and Evans, 1957, 
pp. 88-48, 548-550). It seems reasonable to suppose that if they 
were of Rupununi Phase origin, other almements would have been 
found in the savanna, where there is an abundance of rocks for their 
construction. 
PETROGLYPHS 
Very few petroglyphs have been recorded in the area occupied by 
the Rupununi Phase. One group is mentioned by an early explorer 
as located in the region between the Rupununi River and Lake Amuku 
(Osgood, 1946, p. 21). Another is reported by Farabee (1916, pp. 
88-89; pl. 1, a, ¢) in the savanna between Makatawa and Makamin- 
towa Mountains, 3 miles from the Wapishana village of Ishalton. 
Little can be said about their origin, since no ceramics are known to 
be associated. Farabee (1916, pp. 92-93) says the Wapishanas, the 
present inhabitants of the south Rupununi savanna, disclaim them 
and have no traditions about. them, which leads him to conclude 
they are the work of an earlier people. Judging from published 
descriptions (e. g., Osgood, 1946), petroglyphs appear to be less 
common in the Rupununi savanna than in other parts of British 
Guiana. | 
ANALYSIS OF MATERIAL 
Except for one fragment of turtle shell, artifacts of the Rupununi 
Phase are of stone or pottery. All Rupununi Phase sites produced 
ceramics, and 16 also had stone objects or percussion flakes. . This
