round depression in the middle. Below the band there is also on each side a simi- 
lar circular mark, resembling those often used in zodmorphie celts for indicating 
the eye. ‘This specimen has no hole for suspension. Length 7.3 em., breadth 3 cm. 
(Cat. No. 7232.)

There occurred in this burial-ground at Las Guacas two fi if. I , doubl 
bladed, sharp-edged axes. Figs. 1 and 2, on Pl. XXIV, illustrate one form, which 
is almost semilunar, with two conical sharp knobs on the upper convex side. Figs. 
3 and 4, on Pl. XXIV, show another and commoner form, having two broad blades. 
During the excavations of Padre Velasco similar axes were sparingly found in vari- 
ous parts of the burial-ground. ‘They seem never to have been met with in any 
number. I found a few specimens in my excavations at Las Casitas and one at Las 
Guacas, the latter figured on Pl. I, Fig. 1, and described above. All of these axes 
are of slate and probably served as battle-axes. The measurements of the axes 
illustrated on Pl. XXIV, are the following: 
Fig. 1. Length 20.2 cm., breadth at the center 5.1 cm., thickness 4.3 cm. 
Fig. 2. Length 14.6 cm., breadth at the center 4.8 cm., thickness 3.1 cm. 
Fig. 8. Length 15.9 em., breadth 5.9 em., thickness 2.4 cm. 
Fig. 4. Length 15.8 cm., breadth 4.7 cm., thickness 3.2 cm. 
A unique specimen of a double-bladed ax is illustrated on Pl. XX XIII, Fig. 6. 
It is provided with two elevated parallel and transverse bands representing the 
strings for the hafting. Length 13.8 cm., breadth at the middle 5.2 em. 
(d) Bark-scrapers. 
A number of these small, neat, and elaborately executed tools were in use among 
the Indians of Las Guacas. (Compare the notes upon these objects in the descrip- 
tion of the specimen I found at Las Guacas, p. 31.) Pl. XXIII, Figs. 8, 9, 10, 
shows three bark-scrapers in the collections of Padre Velasco varying in shape. 
Pl. XXIII, Figs. 8 and 9, are both double-grooved. Pl. XXIII, Fig. 10, displays 
three longitudinal grooves on the upper side, the specimen perhaps having not been 
completed by its maker. The measurements of the bark-scrapers on Pl. XXIII, 
are the following:
