quills into holes along the outer margin of the rim. Numbers of the 

 barbs of these feathers have been removed from the quills at short 

 intervals with the result that the chevron pattern of the feathers is 

 much more pronounced. The whole of the resinous surface on the 

 base of the skulls, on the face and orbital protrusions is studded in 

 these three specimens with white siliceous seeds, which are set ob- 

 liquely and in such a way as to form rows, each pair of rows being 

 composed of a series of chevrons. A large number of these seeds 

 have fallen out, but their impressions remain. In skull No. 13 

 jequirity seeds have been used instead of these white ones. 



With regard to the significance of all this ornamentation I will 

 simply quote Mr. Craigen's letter : " As regards the meaning of the 

 nasal and orbital projections, I am unable to give any explanation 

 unless they refer to some totem, but I doubt that, as all the skulls 

 were similarly decorated, and a tribe as a rule has a number of totems. 

 It is a seed at the end of the orbital protrusion, but I do not know the 

 name of the plant. I have always heard that the marks on the frontal 

 bone denote either rank or relationship. As a rule one considers 

 highly decorated skulls to be those of chiefs or men of renown. They 

 do not bother about ornamenting the skulls of prisoners or of enemies 

 killed in warfare. This refers to tribes about eighty miles east, but of 

 the upper Bamu river we are at present still ignorant." 



In conclusion, I have to express my indebtedness to Professor 

 Eeid for his aid in making these observations and also for many 

 helpful suggestions.
