Mr Shrubsall, Crania from Teneriffe. [May 11, 



The palatal index has a range of 61 — 94 with maxima at 78 

 and 89, mean index for the series male, 79'3 ; female, 78"9. 



Cf. L'Homme Mort, 72-7, 



Spanish Basques, 75*2, 

 Grotte de Baye, 75 , 5, 

 French Basques, 79'6. 



Classifying these indices according to Virchow's divisions we 

 find among males well represented lepto- and brachystaphylinic 

 groups with somewhat smaller numbers intermediately. 



The mandible is characterised by the narrowness of the chin, 

 the strength of the muscular impressions and alveolar border ; the 

 eversion of the angle and the prominence of the genial tubercles. 



The mean goniozygomatic index is in the male 77*6, and in 

 the female, 72 - 5, cf. 



Mediterraneans, 77, 

 Mean European, 7 7 "6, 

 Arabs, 74*2. 



Summing up the results of the foregoing measurements it 

 appears that four types of skull existed in Teneriffe at a period 

 anterior to the Spanish invasion. 



I. The first and most important type in respect of numbers 

 presents the features of a capacious skull with moderately pro- 

 minent glabella and superciliary ridges, a well-developed frontal 

 region and full rounded forehead. It has a sagittal curve pre- 

 senting a post coronal depression, a lambdoid flattening and a 

 great filling out and projection of the occipital region of the 

 cranium, while the greatest breadth is bitemporal. The sutures 

 are very complicated, metopism is not infrequent and wormian 

 bones are very prevalent in the lambdoid suture. The face is 

 short, broad above, narrowed below, orthognathous, with low broad 

 very rectangular orbits, a leptorhine sharply cut nose, slightly 

 sunken at the root, an elliptical palate and greatly worn teeth.
