JAMBELI CULTURE — ESTRADA, MEGGERS, EVANS 



493 



until the center of the notch cuts through to the interior (fig. 5, d). 

 Length is 3.3 cm.; diameter at lower edge is 2.0 and 2.2 cm. The 

 other shell is a small OUoa peruviana Lamarck perforated near one 

 end by the same technique. Length is 2.2 cm. 



Carved conch shell. — -A small conch shell (fig. 6, o), 9 cm. long,

 surface; b, Guangala Phase example from La Libertad (after Bushnell, 1951, fig. 24, 1). 



has been decorated with perforations and diamonds by cutting out 

 portions of the surface to a depth of 2-3 mm. It comes from the 

 surface of Site 0-6. In size and construction it is very similar to an 

 object described by Bushnell (1951, p. 62) as a shell box from the 

 Guangala culture (fig. 6, 6). 



Beads. — Sixteen, flat, circular beads (fig. 7, a-d) carved from 

 Spondylus shell come from the surface collection at 0-6: Las Huacas. 

 They are typically two-tone in color, partly red or orange and the 

 remainder white. Three are pure white. Surfaces are usually 

 polished but sometimes remain slightly pitted. The central perfo- 

 ration is slightly conical, the maximum diameter being less than 1 

 mm. greater than the minimum diameter. Diameter ranges from 

 1.4-2.3 cm.; thickness from 0.5-1.0 cm., with a single example of a 

 thickness of 1.0-1.5 mm. Diameter of perforations range from 4-5 

 mm. Thickness is not correlated with diameter, so that some of the 

 thickest beads have some of the smaller diameters. 



Bead blank. — One Spondylus disk (fig. 7, e) 2.5 cm. in diameter 

 and 1.5 cm, thick, from Site 0-6, probably represents a blank for the 

 manufacture of a bead. 



Atlatl hook, — A small object from the surface collection at Site 

 0-6 of red Spondylus shell, carved in the form of a bird head, probably 

 represents an atlatl hook (fig, 8, b). It is 5 mm. thick at the flat 

 base and tapers slightly toward the top. The edges are rounded. 

 There is a perforation 5 mm. in diameter through the center. The 

 surfaces are not perfectly even and blemishes in the shell remain.
