CAL1F0KNIA STONES WITH OBNAMENTATIOK 179 



One of the largest and most nearly symmetrical of the ring-like stones 

 is from the shellheap, and is made of serpentine. This specimen (P. M. 

 1479:8) is 2^- inches thick and 4£ in diameter. The perforation is nearly 

 of the same size throughout, with straight sides, and nearly 1£ inches in 

 diameter. As will be seen by Fig. -19, there is a deeply-cut line around 

 the centre of the stone. All the surface above this line is highly polished, 

 while the portion below it, though smooth, is without a polish. 



A much smaller example (P. M. 14803), cut from a block of steatite, 

 was found in the shellheap, and was broken in three pieces. This is If 

 inches thick by 2 in diameter. The hole is three-quarters of an inch across 

 in the centre, and widens towards each end to about an inch. The ends 

 are smooth, but not polished. Seven FlG - ^ °- 



deeply-cut grooves, at nearly equal 

 distances apart, run around the sur- 

 face of the stone and thus form six 

 ridges, above the upper of which is 

 a wider portion around the hole, and 

 on the bottom the space left is about 

 twice the width of that on the upper 

 portion. The character of this orna- -- — -gs^ sgj 

 mentation is well shown by Fig. 50. Ip^orateciVto^mTsiMui of Santa Cataiina. 



The last of the five from the shellheap is of a depressed globular form 

 with a large perforation. This ornamented specimen (P. M. 13358) is also 

 of steatite. It is about 2£ inches thick and 3f in diameter. The hole was 

 made by working from both ends, and the central ridge was afterwards 

 removed, the hole being now nearly straight, and 1£ inches in diameter. 

 Both faces of the stone are polished, and on nearly one-half of the surface, 

 extending diagonally from the margin of the hole on one face to the mar- 

 gin on the opposite face, are six sets of nearly parallel lines with cross- 

 lines between them, making six bands of a lozenge-shape pattern, as will be 

 seen by reference to Fig. 51. Between these bands are plain spaces.
