type of man buried in the shell mounds, a type with heavy, thick skull, 

 devoid of visible sutures, projecting heavy orbital ridges, extremely low 

 forehead, strong-pointed jaws and eyes close together. The dentition is 

 also interesting, the molars being out of all proportion to the premolars 

 which are abnormally small. (Fig. 3) 



There were no traces of human remains devoured at cannibal feasts 

 and the only bones, aside from the regularly interred skeletons, were 

 those of fishes, birds and reptiles. 



Kobarima Hill. 



This is a high isolated hill about four miles south of the last and situ- 

 ated near the head of Kobarima Creek about three miles from the Aruka 

 River. It is composed mainly of laterites with some granitic rock and is 

 one of the so-called " red hills " of the district. It is covered with a 

 sparse growth of low trees, has little depth of soil, except on its northern 

 slopes, and is at present inhabited by a few Warrau and Arowak Indians. 

 No traces of shells were found, but on its highest, and most barren portion, 

 I obtained a few earthenware heads and two pieces of partly worked 

 stone. (Fig. 4) 



Waunixa Hill. 



This is a lofty (225ft.) hill on the northern banks of the Koriabo 

 River (tributary of Aruka) and dwindles down to the west to the low 

 Akawabi Hills. It is composed largely of laterite, has little fertile soil 

 over a considerable portion of its surface and is a decidedly " i'ed " hill 

 even when viewed at a distance. Here a few very fine stone implements 

 were obtained, as well as several earthenware heads and numerous pieces 

 of highly decorated pottery. (Fig. 5-6) No traces of 9hell mounds or 

 former village sites could be found. 



Akawabi Hill. 

 This is a low eminence, scarcely 35ft. high, on the west bank of the 

 Akawabi Creek about five miles from the Koriabo River. It is of granitic 

 formation with considerable masses of white quartz and with scarcely any 

 laterite. It is covered with a fairly deep and fertile soil and is inhabited 

 by a few Warraus. Half a mile further west are higher hills whereon the 

 Warraus have their fields or provision grounds. This low hill was for 

 many years the site of a Catholic Mission now abandoned, and I understand 

 that the former missionary obtained many excellent specimens from the 

 neighbourhood. Here there were numerous outcrops of shell accumula- 

 tions while fragments of chipped quartz, broken stone implements and 

 pieces of highly decorated pottery, as well as earthenware heads, were 

 picked up in numbers on or near the surface of the earth. Excavations 

 were carried on in this spot and revealed much of interest. (Fig. 7) The 

 layer of shells was from three to six feet in depth and bore evidences of 

 more ancient origin than those at Barambima Hill. In most places it was 

 very barren of relics. Near the surface and in the loam above the shell 

 deposits were many pieceB of decorated pottery (Fig. 8) and among the
