1(^4 THE ABORIGINES OF PORTO RICO [eth. ANN. 25 



regions are very imperfectly indicated. The knob is siuull. not prom- 

 inent, the boss hirge, and the panels are obscurely indicated. The 

 surface is much worn. A slender collar is described and figured by 

 Professor Mason as follows: 



The shoulder is distinctly bell-shaped, having a pecked chamfer on its outward 

 portion. The transverse shoulder ridge is quite prominent. The right or plain panel 

 is inclosed in a quadrilateral ridge, which bears on the middle of its anterior and pos- 

 terior sides a very marked swelling. This is a constant feature on the anterior and 

 posterior margins of the panel on the shouldered side whenever this panel is pres- 

 ent. The face of the panel is bounded ))>■ a border ridge and ornamented by a large 

 ring in the center, on either side of which a human leg drawn up is represented. The 

 anterior margin of this panel, which I have called the panel border, is a double 

 scroll. 



In c the knob i.s confluent with the band, and the latter is separated 

 by some distance from the undecorated panel border, which is more 

 pronounced than it usually is in slender collars. About midway in its 

 length this panel border has a slight elevation, and there is a pro- 

 nounced groove separating the undecorated panel liorder from the 

 boss. In the middle of the undecorated panel is a pit which is quite 

 indistinct in the figure. 



The boss is low and slightly inclined toward the undecorated panel. 

 Its surface is rough as compared with the other parts of the collar 

 except the undecorated panel. The decorated panel is smooth, desti- 

 tute of ornamentation, and bounded by a smooth panel ridge. The 

 surface of this collar, which is one of the best in the collection, shows 

 signs of much handling. 



The i-emaining collar {d) is larger than the last-preceding one, and 

 has a much rougher surface. The knob is tiiangular or pear-shaped, 

 and confluent with the surface of the collar on the sides. The l)and is 

 not represented, this being one of the few specimens of slender col- 

 lars from which it is missing. 



The undecorated panel has a long shallow depression that occupies 

 almost its entire length, and the undecorated panel l)order and ridge 

 are only obscurely indicated. The boss is more pronounced than that 

 of specimen a, plate Lxvi, and its top tips slightly to the left. 



The decorated panel has an obscurely indicated panel groove and is 

 slightly sunken below the level of the adjacent surface of the collar. 

 It IS smooth and without superficial ornamentation. 



In figures 26 and 27 is shown a view of a slender ovate collar taken 

 from the side of the decorated panel. The boss of this specimen 

 appears to be truncated, and the depression in the undecorated pane! 

 is large, occupying almost the whole surface of the panel. The band 

 is broad and the knob button-shaped. There is a space ))etween the 

 undecorated panel margin and the band, the diameter of which is 

 slightlv greater than that of the collar below the knob. The ear-like
