This flattening of the tibia is peculiar to the higher apes also, hut as Prof. 

 Wyman properly remarks, it is not so much the lateral flattening, as the round- 

 ing of the angles, and the bending of the shaft forward, which gives to it a 

 distinct ape like character. The Omori tibia possesses this character in a mark- 

 ed degree. 



This peculiarity associated with its lateral flattening, gives greater importance 

 to the bone, and may he looked upon as an evidence of considerable antiquity 

 of the remains found associated with it. 



Since writing the above, I have examined a shell mound of immense size in 

 the province of Higo. 



The bones of mammals were not numerous yet of forty fragments found, 

 more than half were those of man. They were all broken, «and were scattered 

 promiscuously through the deposit. Fortunately, fragments of a number of 

 tibia were found, and these were all platycnemic. Oue showed an excessive 

 lateral flattening, giving an index of 50.2, this being one of the lowest ever 

 recorded. 



the human hones were remarkable for the roughness find prominence of the 

 bony ridges for muscular attachments. 



A description of this mound with its pottery, etc. will be given in a future 

 memoir.
