FEWKBs] CULTURE AREAS IN THE WEST INDIES 197 



111 several of the decorated panels we find this circle doubled; 

 or these duplicated circles may be connected or modified in such a 

 way as to appear aS spirals;"^ or at times i:iarallel lines may extend 

 from the circles. The figures on the decorated panels of several 

 collars consist of geometric parallel lines arranged in squares and 

 chevrons, a form of decoration sometimes found on panels of massive 

 collars. Tiiese are regarded as decorations of the body of the animal 

 or the luiman form represented. 



The main difference supposed to exist between the Bremen collar 

 and other examples of its kind would seem to be the modification 

 of the projection or knob into an animal head, and yet when we 

 examine a series of collars we find several specimens in which the 

 projection is carved in such a way as to suggest the conventional 

 head of some animal. 



Many massive stone collars "- and some of the slender ovate "" 

 varieties have two "knobs," one of which projects on each side of a 

 binding band or shoulder band filling the interval between them. 

 In one instance the two ends are not united by a band but are hooked 

 together. 



No decorations appear in any of these double knobs, and all are 

 without eyes or other indication of the presence of a head, which is 

 likewise true of those examples in which the projections do not rise 

 above the surface of the collar, although a remnant of the shoulder 

 band "^^ may in these cases sometimes survive. 



When the projection bears any design, it is commonly flattened, 

 with a pit on each side. Another form of simple flattened knob, hav- 

 ing circles on each side and parallel lines between them, is found on 

 the second Bremen specimen. In an example in the Heye collection, 

 where the projection is not very prominent, it is marked l)y a single 

 transverse and several parallel grooves, recalling the parallel lines 

 between the pits in an undescribed collar in the Bremen Museum. 



The simplest interpretation of these variations in the so-called pro- 

 jection or knob of a stone collar would be that, like that of the Strube 

 specimen, it represents a highly conventionalized head, and that the 

 accompanying pits or circles are eyes. 



Although several forms of stone collars have been added to those 

 known to the author when he published his account of the Aborigines 

 of Porto Rico, and one or two new theories concerning their use have 



" This form suggests the ornamentation of a fragment of a specimen of doubtful 

 relation in the Stahl collection, now in the American Museum of Natural History, New 

 Yorli.
