fourteen of these it occurred on both sides, making 46 reversed 

 pterions out of a total of 300 (15.3 per cent). Krause also 

 reports epipteric bones in 31 crania (on both sides in 18). 

 The Papuans are also noted for the relatively great number 

 of irregularities in the pterionic region. In a collection of 

 fourteen crania from New Guinea belonging to Yale Uni- 

 versity Museum, I found the reversed pterion in five (on both 

 sides in four of these) ; while epipteric bones were present in 

 seven out of the fourteen crania. Dorsey 1 also found a high 

 percentage of irregularities of the pterion in a series of twenty 

 crania from New Guinea, only half of them having the normal 

 pterion in H; two crania with pterion in K, four with pterion 

 reversed by a frontal process from the temporal bone, and 

 four with epipteric bones. Thus the natives of New Guinea 

 as well as of the islands directly to the east are characterized 

 by an unusually high percentage of anomalies in the region of 

 the pterion. 



Articulatio spheno-maxillaris. A union of the ala magna 

 of the sphenoid with the superior maxillary; i. e., the failure 

 of the cheek bone to reach the fissura orbitalis, takes place in 

 nineteen out of twenty-three skulls (82.6 per cent) and as 

 follows :
