A DESCRIPTION OF SIX EAST AFRICAN SKULLS, WITH 

 MEASUREMENTS, INDICES, AND TRACINGS OF SAME, 



by 



A. ELMSLIE CAMPBELL M.A. 



In the following examination of six skulls from Southern Nigeria, the 

 measurements and indices are those adopted by Flower, with the addition of 

 the altitudinal index of Duckworth. In the appended consideration of each 

 skull the plan advised by Duckworth is followed. The accompanying tracings 

 of the normae laterales of the skulls were made with the dioptrograph and 

 reduced to one half of the natural size. 



1. YORDBA SKULL FROM ABEOKUTA, S. NIGERIA. 



Length, 181 mm. 



Breadth, 129. 



Cephalic index, 713 (Dolicho- 

 cephalic). 



Height, 127. 



Altitudinal index, 702. (Tapeino- 

 cephalic). 



Basinasal length, 86. 



Basialveolar length, 94. (Alveolar 



margin absorbed). 



Alveolar index, 1093. (Prognathous). 

 Nasal height, 44. 

 Nasal width, 30. 



Nasal index, 682. (Platyrhine). 

 Orbital width, 36. 

 Orbital height, 33. 



Orbital index, 917. (Megasemic). 



Consideration of the skull : 



Cranial portion. The transverse curve is scaphoid. The sutures are 

 normal but very tortuous. On the right the frontal, parietal, squamosal, and 

 sphenoid bones meet at a point, i.e, there is no parieto sphenoid suture. 



Facial portion. The lacrymo-ethmoidal suture is present. The infra- 

 orbital suture does not persist. The nasal aperture is broadly ovoid. The nasal 

 spine is median. The nasal bones are irregular in shnpo, the right being broader 

 but shorter thnn the left.
