CRANIA FROM THE MOUNDS OF FLORIDA. 383 



In the region of the origin of the temporal muscle the temporal ridge was 

 interrupted in seven examples, and not interrupted in three ; two of these being- 

 females. In this series, therefore, the interruption at the stephanion in the 

 curve of the temporal ridge was a good sex character ; indeed, better than the mar- 

 ginal process of the malar bone, which, while present in one female, was absent in 

 the other and was almost absent in two males (Nos. 456, 1,286). — The lambdoidal 

 suture as it approached the asterion became harmonic in seven (all males) and 

 serrate in five, two of which were females. — The interval between the temporal 

 ridges at the sconce had a minimum of 86 mm. and a maximum of 158 mm., an 

 average of 122 ; omitting the two females the average was 112 mm., which is greater 

 than that of the Moore series. — A remarkable feature in which the Seminoles 

 agree with the Moore skulls is the horizontal groove on the inner side of the malar 

 bone, which was present in all the specimens. In six crania the malar bone entered 

 the spheno-maxillary fissure ; in four it did not. 



The lower jaw was present in seven of the skulls. The condyloid process was 

 angulated in all, the median facet being inclined. The base of the coracoid process 

 concealed the third molar in whole or in part in three; one of these (No. 1,286) 

 was a female. The mental foramen opened between the premolars in four on both 

 sides, in one as above on the left side, but opposite the second premolar on the right 

 side. In two specimens only (Nos. 733, 698) the foramen lay between the second 

 premolar and the first molar. The teeth were well developed, only two specimens 

 showing the second upper molar with less than four cusps, and the second lower 

 molar with less than five.

(5) Description of a Series of Skulls of North American Indians Collected 

 West of the Rocky Mountains (mainland). After the Florida crania had been 

 studied it was determined to compare them with a group as remote as possible both 

 in geographical and ethnographical range. For this purpose the skulls of Indians 

 from the Pacific Coast were included with those collected from localities as far east 

 as the Rocky Mountains. While this enormous territory is occupied by tribes dif- 

 fering greatly among themselves, it is true, that in the California " Digger," the 

 Shoshoni and the Pawnee the lowest point in skull conformation in the Indian 

 is reached^ while the variations in structural details throughout are more striking 

 than in skulls from other parts of North America. Unless specially stated the 

 specimens are to be found in the collection of the Academy.
