Two crosses within each other, encircled by a curved line, forming an angle at every one of the corners of the outer cross. The lines of the inner cross were nearly six cm. broad. At the upper and lower ends of the outer cross was an isolated rectangular elevation, and a more or less square one in each of the angles of the cross. The length of the inner cross was 16 cm., of the outer one, 28 cm. The greatest diameter of the surrounding curved figure was 48 cm. All the above described rock-carvings, viz. _a-k_, were to be found on the level summit of Cerro de Pantheon; _k_ was situated almost at the centre of the plateau, its upper short arm pointing exactly northwards. This circumstance may perhaps be fortuitous; nevertheless it ought to be mentioned, because the arms of _i_ are also directed towards the four principal points of the compass. Pretty near _a_ was the beginning of a small round water-worn rock-hollow, 30 cm. in diameter. _l_ Pl. 39. A winding line, one end of which formed a not quite regular spiral, and the middle portion several irregular flexions and angles, the other extremity being perfectly straight. This winding line was cut in the solid rock at the promontory Punta de Pantheon. _m_ Pl. 39. A double figure consisting of a labyrinth-shaped carving, united with a spirally wound line, the outer circumference of which was formed by almost square tongues, and the inner part by an irregular spiral. The length of the labyrinth-shaped figure was 58 cm., the greatest diameter of the spiral figure 54 cm. It was sculptured in the solid rock near the preceding figure, at the extremity of the promontory, and was now partly covered by water. _n_ Pl. 39. Almost identical in form with the spiral figure of the preceding carving, but more regular. The inner spiral had more turnings, four in number. The greatest diameter, if the projections are included, was 86 cm. It was also cut in the solid rock at the promontory itself, near the line of water. _o_ Pl. 40. A queerly composed figure. The greatest length was 109 cm. It was found some little way from the shore at Punta de Pantheon, cut in the solid rock. _p_ Pl. 40. Some coarsely carved faces; only one had the nose marked, the other four exhibiting only eyes and mouth. The length of the largest face was 25 cm., of the smallest 20 cm. A little spherical excavation, a rock-hollow, was to be seen between two of the faces. They were carved in a loose block of stone, about two meters in diameter, lying a little way up from the shore.
