124 THE ABORIGINES OF POKTO KICO [eth. axn. 25 



The face is clearly cut, having well-made nose, eyes, and mouth. 

 The decorated frontal band ends on the sides in spirals forming the 

 ears. The general appearance of the face is human rather than I'ep- 

 tilian or frog-like, recalling in several features specimens of the tirst 

 type with human heads. 



Perhaps the most instructive feature in this specimen is the arrange- 

 ment of the organs represented on the region opposite that on which 

 the face is cut, or that between the apex of the conical and posterior 

 projections. The apex takes the form of a small rounded knob just 

 above the frontal fillet. From the shallow groove that separates the 

 apical knob from the backV)one arise the anterior appendages, which 

 closely follow the outline of the headband, extending ))elow the mouth, 

 where they end in representations of hands, the lingers being indicated 

 by five parallel lines, above which are incised the armlets and bracelets. 



The backbone is represented by three pairs of rectangular \'ertebrEe 

 inclosed in extensions from the shoulders, each with a central pit. Six 

 pai'allel, slightly curved lines on each side mark the ribs. 



The posterior appendages are retracted, with knees pointing forward 

 and feet drawn together and toes extending backward. There are 

 depressions at the proximal end of the thighs, as in other specimens, 

 and in the outward-turned soles of the feet are semicircular depressions 

 surroiuided by an incised line, a feature which we find often repeated 

 in other graven images of the foot. Just below the feet is a beading, 

 or elevated band, connecting the rim of the base on each side. This 

 structure appears to be confined to the three-pointed stones of the 

 second type, and will be referred to as the posterior band. 



It will be seen in comparing this specimen with others of the same 

 or different types that nowhere else do we find so many parts of the 

 body represented. If three-pointed stones are homologous, and the 

 conoid projections of all are morphologically the same, it is evident 

 that this structure belongs to the head region and not to the body or 

 any part below the shoulders; in other words, the conoid projection is 

 an appendage of the head and not of the back. The batrachian sem- 

 blance which Professor Mason discovers in this specimen is not appar- 

 ent, for the face, as well as limbs and body, seems to be strictly human. 



The three-pointed object figured in plate xLvii, where it is repre- 

 sented from side and rear, is one of the best examples of three-pointed 

 stones of the second type. It is said to have been found near Baya- 

 mon, Porto Rico, and was purchased from Seiior Angel is, of Catano, in 

 1903. The object is made of a black stone with finely polished surface 

 probably once covei'ed with a resinous gum. The face depicted upon 

 it is grotesquely human, the conical projection is low, the anterior and 

 posterior ends are pointed, the nose is slightly protuberant, the mouth 

 wide open, and the ears are formed like the figure fi reversed. The 

 back of the specimen is decorated with incised lines — a circle with a
