Mr Shrubsall, Crania from Teneriffe. [May 11 3 



The fronto-zygomatic index of skulls from Teneriffe is for 

 males 833 and for females 89.

This series of crania may readily be classified into two groups 

 according to the complication of their sutures. In the first and 

 smaller division the sutures are simple and wormian bones the 

 exception ; while in the second series the sutures, more especially 

 the lambdoid and coronal, are excessively complicated, while it is 

 rare to find even the sagittal suture simple and wormian bones 

 are very common. A persistent metopic suture is to be found in 

 about 8 per cent, of crania of the second series ; it may be com- 

 plete, or persistent near either the bregma or the glabella, the 

 latter arrangement being the more frequent. 



Synostosis usually commences in the sagittal and lower part 

 of the coronal sutures ; contrary to the usual custom the lambdoid 

 suture is quite the last to close. M. Verneau indeed describes a 

 case in which the squamous suture had closed up while the lamb- 

 doid was still open, 



Wormian bones are the rule in the lambdoid suture, the com- 

 monest arrangement being a series with their long axes nearty 

 vertical and their short axes arranged along the line of the suture, 

 the two sides being frequently asymmetrical. There may be a 

 single 'os-epactal' or an 'os-epactal' with a small median wormian 

 bone in front of it. 



Passing on from the study of the cranium to that of the face 

 we find a considerably greater range of variation. Faces from
