MASSIVE COLLARS 



Plate Lxiii, a and ^>, shows two specimens of massive stone rollars, 

 both collected by the author from Porto Kico. In a the boss can not 

 be differentiated from the body of the object, and the decoration of 

 the panel is obscure, consisting of a simple series of incised grooves 

 of chevron form covering the whole face of the panel. There are two 

 knobs, but the band is inconspicuous. This is a very heavy collar 

 and could not be ti'ansported any consideral)le distance without fatigue. 

 The form is oval, almost circular, not ovate. 



Specimen 5, on the same plate, is a massive oval collar in which the 

 panel is also indistinct and is undecorated. The boss is nnssing, and 

 there is but one projection, which is, however, exceptional in having 

 an indentation on each side. The band is in low relief, flat and broad. 

 This collar has a suggestion of an angular ridge on the side turned to 

 the observer. The panel has a panel groove and ridge, which are 

 brought out in the illustration by means of chalk in the groove. 



Plate LXiv, a and ^, represents a typical form of the massive collars 

 collected by the author in Poi-to Rico. The collar a is so placed 

 that the double knob is on tlie right side, the band being a broad, slight 

 elevation. The undecorated panel adjoins the upper knob; the boss is 

 missing, and the decorated panel is turned from view, the decorated 

 panel groove appearing as three triangles, two of which are obscurely 

 shown. 



The massive collars represented in plate lxv, a-t\ are typical forms. 

 Specimen a is destitute of a decorative panel, but has a flat, noncon- 

 fluent, undecorated panel, extending from the end of the knob, that is 

 evidently double as far as the region of the boss. The shoulder is 

 more or less angular, and there is no sign of the band. 



Specimen li also is of the massive type, with knobs, between which 

 is a l)road band in low relief. The decorated panel border of sjjeci- 

 men h is pinched into triangular ridges, but the panel itself is without 

 design. The shoulder is inclined to be angular, but not so markedly 

 as in the other specimen in this plate. 



There are but slight diflerences in various specimens of massive 

 collars, yet such as exist are readily .seen. Two massive collars are 

 figured in plate lxv, c and f/, both from Porto Rico. An examination 

 of d reveals the fact that the undecorated panel does not conform in 

 curvature with the surface of the collar as in the example illustrated 

 in the previous plate, but is flat, extending from the neighborhood' 

 of the knob and band to the region of the bo.ss, which is absent from 

 all massive collars. 



The collar represented in plate lxv, e, is somewhat better made 

 than most collars of the massive type, and is more rn-lily decorated. 

 .Vn example is here shown with a plain, undecorated panel, and double
