The author devoted special study to the pictographs near Utuado, 

 at other points along the Rio Grande de Arecibo, and in the caves 

 near Manati, especially in the Cave of the Swallows, previously 

 referred to. These pictographs are usually circular figures repre- 

 senting faces or heads with prominent ears, and sometimes with 

 horns. When, as sometimes happens, bodies are represented, the 

 limbs are appressed to the sides. No animal pictures are to be seen, 

 unless certain zigzag figures may be interpreted to represent snakes. 

 But geometrical figures, as spirals, circles, triangles, and rectangles, 

 are not uncommon.^
