rim and project 8-15 mm. outward. They may be single or in a 
series separated by notches 4-7 mm. wide. The lip is rounded. 
Rim diameter 14-26 cm. (fig. 53-1, bottom). 
2. Large globular jars with vertical neck and slightly thickened, 
everted rim with a wide channel on the inner surface where the 
body wall and the rim join. The total width of the everted rim 
ranges from 1.8-2.2 cm. with the channel usually 1.0-1.3 cm. wide. 
Lip is flattened. Rim diameter 18-26 cm. (fig. 53-2, bottom). 
3. Jars with a short to medium neck and exteriorly thickened rim. 
The rim profile varies from triangular with rounded corners to 
many-sided with a rounded lip. Rim thickness 1.0-1.6 cm.; mouth 
diameter 15—24 cm. (fig. 53-3, bottom). 
DecorATION (pls. 35, 36, f—-)) : 
Technique: Wide incised grooves sometimes in combination with low relief 
applique modeling. Grooves are broad (3.5-5.0 mm.) shallow (less than 
1 mm.) and vary from clear and distinct to barely visible. Width is 
generally uniform on a single sherd. They were executed with a tool 
that had a slightly serrated end leaving faint parallel lines in the base 
of the groove. Lines were drawn when the surface of the clay was wetter 
than in Koriabo Incised, resulting in less sharp definition of the grooves. 
‘Sometimes the grooves are so closely spaced that the separation between 
them is about the same width as the groove, giving the effect of strips of 
low applique. Modeling consists of small, low applique nubbins, ribs, eyes, 
and faces, 1-3 mm. high and 5-15 mm. in diameter. Occasionally the 
applique is ornamented with fine lines or parallel nicks. 
Motif: Parallel lines arranged vertically on the body exterior or on the 
interior surface of wide everted rims; spirals with a small applique eye 
at the center; parallel curvilinear elements; sinuous lines winding back 
and forth across the wide-flanged rim. The applique nubbins, eyes, and 
faces are usually on the upper edge of the wide rims or on the lip. 
TEMPORAL DIFFERENCES WITHIN THE TYPE: None discernible in the small sample 
(Appendix, table 19). 
CHRONOLOGICAL POSITION OF THE TYPE: A mihor type restricted to the middle of 
the Koriabo Phase sequence (fig. 57). 
UNCLASSIFIED DECORATED 
Brushed: One sherd from N-2, Cut 3, level 0-8 cm. is ornamented with many 
deep, parallel lines as if the surface had been brushed with a bunch of stiff 
twigs. Paste and color are typical of Warapoco Plain. 
Imitation of Mabaruma Incised: A typical channeled rim sherd of Koriabo Plain 
Form 5, from the surface of N-2, has a lobe in the form of an “eye” with 
grooved incisions around that is typical of Mabaruma Incised in both tech- 
nique and motif. Rim diameter 26 cm. 
Modeled:. Four sherds from the surface of N-2 have low prack Pasar nubbins, ribs, 
and eyes. The paste characteristics suggest the plain pottery of the Koriabo 
Phase rather than trade from the Mabaruma Phase, but the modeling is not 
typical of either Phase. All the sherds are too small to show overall design. 
Punctate: One sherd from N-2, Cut 3, level 0-8 cm., has a small applique nub- 
bin 4 mm. high and 6 mm. in diameter surrounded with a row of punctates 
2 mm. in diameter and 1 mm. deep and spaced 6-8 mm. from the nubbin. This 
decoration is on the exterior just below the rim so that the circle of punctates 
reaches the lip. The vessel is a small bowl with slightly incurving side 
walls, a direct rim and rounded lip, with a mouth diameter of 16 cm.
