134 THE ABORIGINES OF PORTO RlOO [eth. anx. L'5 



lenticular form, which in rare instances is altered bj- prolongations 

 of the forehead and chin. Disks have no sign of a diilerentiated basal 

 region. 



The head tigured in plate u. <(. is tlius described by Professor Mason: 



Mask of gray volcanic material. The head and foot are .simple knobs. The fore- 

 head and cheeks are furrowed and the bottom elevated and very hollow. Length 

 8.a"i, width 4.8, height 6.2-5 inches. 



Tliis object, shown in face view (r/) and in ])rotile ((i'), is three- 

 pointed in form, the anterior and posterior points appearing as kno))s, 

 the conical projection representing a human nose. The l)ase is slightly- 

 concave l)ut not sepai'ated from the head, showing .signs of onc(! having 

 been fitted on another body, to which it may have ))een lashed by cords 

 passing over the two ends. 



Specimen h^ J', of plate i.i is more nearly globular, the liead rising 

 in high relief from a basal region continued anteriorly and posteriorly, 

 the former extension situated on the forehead, the latter at the throat. 

 The sunken eye sockets are surrounded by an amudar ridge, which is 

 repeated about the mouth. The nose is small and cut in low relief. 

 The base is flat. 



The head shown in fac(> vieM' and in profile, plate lii, <i and a' , has 

 both chin and forehead iimch elongated, forming cleats on which are 

 grooves for a cord used in attac^hing the head to a foreign body. An 

 ear (see «') is obscurely indicated on one side. This specimen bears a 

 rude imitation of a head on the lower projection apd of legs on the 

 rrpper one, or the forehead, in this respect suggesting the first type of 

 three-pointed stones. It appears tha't this specimen represents either a 

 compoiuid of a stone face and a three-pointed idol or a unique stone 

 head with lateral appendages. 



The stone specimen tigured in this plate us h and ?/, from the Zeno 

 Gandia collection, is one of the finest of these objects yet found. 

 The incised decoration of the band above the forehead consists of cir- 

 cles, triangles, and other markings, portions of the nose and lips being- 

 indicated in the .same way. The ears, rarely found in stone heads 

 of this form, are slight projections at the ends of the frontal band. 

 ^Markings indicative of former lashing to another body are clearly 

 shown. 



While' specimen c, c' of plate Liii exhil)its the same general form as 

 that last mentioned, it is more roughly made and destitute of surface 

 decoration. Whereas the base of the former is slightly concave, that 

 of the latter has only a slight curvature, the ba.sal region being only 

 slightly differentiated from the facial and the line of separation show- 

 ing well in the profile. Professor ]Mason dismisses this .specimen with 

 the following brief mention: 



I\Iask of mottled volcanic stone. The ends are simply rtmnded and Uie bottom 

 hollow.
