bone as originally described and named by Tschudi and figured in Hamilton 
Smith. I think a good deal of light is cast upon the appearances and the 
homology of this bone, and of bones closely resembling it, by some specimens 
I have now to describe. 
A very fine example of “ unpaired ” bone occurs in a skull (No. 970*) of 
an Australian aboriginal (fig. 1). This is undoubtedly a true inca bone. The 
subject in whom it occurred was a remarkable character. He was the 
lowest and most animal-like in habits of any of the aboriginals ever seen 
by the police here, and he spent his latter days in confinement as a criminal 
lunatic. It is interesting to know that he was the fellow-countryman of

Wilhelm Krause describes about 200 skulls of Australian aboriginals 
in the Verhandlungen der Berliner anthropologischen Gesellschaft, 20th 
November 1897. He says (p. 516) : “ The lambdoid suture was found in 
82 of 185 skulls, or in 42’9 per cent. ; also one or more ossa intercalaria up to 
21 (No. 170). A real os incae could not be found; but an os interparietale 
forming the point of the squama occipitalis occurred five times (Nos. 18, 27,
