beneath the other. As in the case of R-21, no other vessels or sherds 
indicative of habitation or cemetery sites could be found anywhere 
in the vicinity. 
The vessels are both Kanuku Plain Form 1 b, with rounded bot- 
toms, irregularly curved walls, undulating rims and a contour that 
is not perfectly circular. The upper bowl is the larger: height 11.0 
to 11.3 cm.; rim diameter 41 cm.; body wall thickness 1 cm., narrow- 
ing to 5 to 7 mm. at the flattened to rounded lip. The lower bowl 
is 8 cm. deep, 36 to 37 cm. in diameter and has a rim thickness of 
4 to 5 mm., increasing slightly at the body wall. The irregular lip 
is flattened to rounded, depending on the area of observation. 
These two specimens are now in the collections of the Division of 
Archeology, U.S. National Museum, Washington, D.C. 
DATA FROM OTHER INVESTIGATIONS 
Except for stone implements that have been found and saved by 
local residents, very little additional archeological information is 
available on the Rupununi Phase. However, what does exist cor- 
responds in all respects with the data gathered in the 1952 survey. 
HABITATION SITES 
R-40: ARUA 
Subsequent to our visit to the Rupununi, Dr. C. R. Jones, at that 
time Government physician to the Amerindians, made a surface col- 
lection of sherds from a site where the Arua Creek joins the right bank 
of the Rupununi River, some 30 km. above the village of Yupukari. 
He describes the area as follows: 
It is called Arua from the abundance of Arua palm (used in thatching) found 
there. These fragments were scattered on a small hill where present-day 
Macushi are cutting fields. The soil is covered with lateritic outcrops and all 
fragments were more or less on the surface. I dug one pit but found nothing. 
The Macushi just shrug their shoulders and say “old time stuff.” But no one 
can ever remember anyone ever decorating pots in this district. [Letter of 
May 19, 1954.] 
The latter remark refers to the unusual amount of modeled decora- 
tion represented in the sherd sample (fig. 123, a, c, d). The sherds 
were donated to the U.S. National Museum, Washington, D.C., and 
are now in the collections of the Division of Archeology. Subse- 
quently, the same site was visited by Jens Yde, who made a collection 
for the National Museum, Copenhagen, Denmark. 
CEMETERY SITES 
TIREKA : 
Tirka Mountain is on the southern flank of the Pakaraima Range 
about halfway between Annai Village and the Ireng River. At the 
time of our visit to the Annai area, we heard reports of a cave on the
