The ethmoid and the ethmoidal cells have been displaced artificially and 

 cane strung through the spaces thus forme 1 for carrying purposes. 



The arrangement at the right pterion is normal ; on the left sule there 

 is a small epipteric bone. The alveolar margins are high. The hard palate 

 is deep. The sutures show the normal crucial form Oil both sides in front 

 of the posterior palatine foramen, another foramen is formed by an over- 

 arching spicule of bone, for the anterior palatine vessels. 



The glenoid fossae are deep. The spinous processes are broken off. The 

 basilar suture is closed. Most of the ridges and surfaces for insertion of 

 muscles are well marked. 



Dentition. All the permanent teeth have been erupted. The teeth 

 present are all sound. 



The mandible is absent.

While the number of skulls measured is much too small to form the 

 basis of any definite statement, the tendency of the skull is shown to be as 

 stated above : 



Dolicho-cephalic. 

 Metrio-cephalic. 



Prognathous. 

 Platyrhine. 



Megaseme. 



The closer correspondence between the skulls of the individual tribes will.be 

 noticed, especially in the case of the two Yoruba specimens. Specimen No. 4 

 seems to be slightly abnormal in some respects.
