BRAZILIAN ROCK INSCRIPTIONS. 143 
sist of a single circle, or several concentric circles, the outer one, 
only, being rayed, but on the side of the great rock on the top of 
the Serra is a figure a foot in diameter (Pl. 5, fig. 10), and very 
distinct, fermed of two concentric circles, each with a few lange, 
tooth-shaped rays. Part of this figure is obliterated. At the same 
locality is another figure consisting of a circle with serrated rays 
with only a spot in the centre. 
Not infrequently, on the painted rock at the western end of the 
Serra, occur circles, single or double, sometimes nucleated, which 
bear rays only on the upper side, Pl. 5, fig. 12, Pl. 6, fig. 1. 
There are rayed spirals as well, Pl. 4, fig. 3. Some of these 
appear to represent stars. They are either drawn or impressed. 
In some cases the palm and fingers were covered with wet paint 
and then pressed upon the rock. Whether these figures always 
represent stars is doubtful. At the western end of the Serra is a 
curious rayed head, ornamented on top with what looks like a 
queue, suggesting a comet. At the same locality is the remarkable 
figure, Pl. 4, fig. 9, three and one-half feet high, which looks as 
though it might represent the impersonation of the sun. Just 
west of the tower-like mass is a rock face covered with a large 
group of what are apparently figures of the heavenly bodies. 
They are represented in Pl. 5, fig. 1, and are large and distinctly 
drawn. The whole group is some six or seven feet long. Of 
animate objects the human form and human face are very fre- 
quently delineated. They are all exceedingly rude and are just 
such figures as children are fond of drawing. Sometimes 
body and limbs are represented each by a single line, as in Pl. 3, 
figures 3 and 8. 
It is noticeable that human figures are never drawn in profile, 
which is the rule with similar drawings by North America Indians 
(Catlin).. The eyes and mouth are usually alone represented, one 
eye being often smaller than the other. There is often no nose, 
or a heavy V-shaped curve is drawn over the eyes, the apex pro- 
jecting down more or less between them, representing the nose, as 
in Pl. 3, fig. 1, Pl. 4, figures 12 and 15. 
In some ancient pottery to be described in a future paper the 
same peculiarity is observable in the representation of the human 
head, the eyebrows and nose forming a prominent T-shaped ridge. 
As the most of the busts in terra cotta show the head flattened 
from before backward, I would suggest that the Indians who made
