16C THE ABORIGINES OF PORTO RICO [eth. ANN. 25 



panel is inolosed by a ridge with the prominences, and is rough pecked over its inte- 

 rior space. The left panel is inclosed- by a ridge, and was formerly well ornamented, 

 but it is now nearly worn off, whether by use or time I cannot say. The panel 

 border is a delicate double scroll, having two of the volutes perforated. The boss, 

 which in most of the slender collars is an immense swelling, oblique to the plane of 

 the stone, is in this specimen rolled out like a pouting lip. 



Specimen a, like the collars on the last-preceding plate (lxvi). has 

 a finely decorated panel border, with much the same design as charac- 

 terizes them. The s^'mbolism of the figure is not apparent, but the 

 region near the boss resembles a human face with eyes and mouth. 

 Below the chin are two lateral extensions that might be compared to 

 arms, and below these is a body with posterior appendages. The same 

 tigure is repeated in reverse order, ending with what might be called 

 a representation of the head. It is apparent that if tlie design cut on 

 the decorated panel border of this collar is intended to represent a 

 human face, arms, and legs, these are highl}' conventionalized. 



Professor Mason writes of this specimen, c, plate lxviii: 



The shoulder is well set off from the stone, and is subtendeil by a very shallow 

 riilge. The left panel has the marginal prominences and oval depression. The right 

 panel is inclosed in a ridge looped at tlie upper anterior corner, whicli is continued 

 to form a part of the panel marginal scroll. Tlie panel is ornamented with a dotted 

 circle at each end, inclosed in a sigmoid ridge, the ends of which expand gracefully 

 to fill the triangular spaces between the sigmoid, tlie circles, and the border ridge of 

 the panel. The boss is ridged up on the inside. 



The undecorated panel has a broad liorder. a long, deep pit, and a 

 prominent boss. The band is separated a consideraljle distance from 

 the undecorated panel border, and the knob is prominent, with a slight 

 depression on each side. The collar is well made, and the surface is 

 smooth with the exception of that of the undecorated panel. 



Specimen d of plate lxvii also has an elaborately cut panel border, 

 the detail.s of which are better brought out in i.xviii, </. This collar has 

 a prominent boss and a smooth decorated panel with an obscurely indi- 

 cated border which has a slight protuberance midway in its length on 

 each side. The knob is very pronounced, and the band is olwcure, being 

 a swelling in the collar with undetined limits. The specimen is unlike 

 most slender collars in having the diameter of the region between the 

 decorated panel border and the knob somewhat less than that of the 

 region near the knob. 



The ligures introduced on plate lxviii represent the decorated panel 

 border and surface of three slender ovate collars, which are shown in 

 former plates. It will be noted that there is only the most distant 

 likeness between the figures, but all have circles as the most prominent 

 ornamentation. 



These three figures, from Mason's catalogue of the Latimer collec- 

 tion, show other decorations of slender collars on the panels. In a 

 there is ;i circle in the middle of the panel, with markings which
