one face only of which was worked and was struck in a manner 

 somewhat similar to those of the Chellean stage. 



As regards the human remains discovered, including the canine 

 tooth, there is nothing in their mode of occurrence to favour the 

 idea that they may have helonged to different individuals. Putting* 

 aside the human remains and those of the beaver, the remains of 

 the fauna all point to a characteristic land fauna of Pliocene 

 age ; and, though all are portions of hard teeth, they are rolled 

 and broken. 1 The human remains, on the other hand, although 

 of much softer material, are not rolled, and the remains of 

 beaver are in a similar condition. It would, therefore, seem that 

 the occurrence of these two individuals belongs to one of the 

 periods of reconstruction of this gravel, though for other reasons 

 before stated by us, this is not perfectly certain. 2

 Tooth oe JEoanthropus dawsoni, and some Associated 

 Mammalian Eemains. [A. S. W.] 



EOANTHROPUS DAWSONI. 



A further study of the cranium of JEoanthropus shows that the 

 slight longitudinal ridge along the outer face at the hinder end of 

 the parietal region is not median, but one of a pair such as fre- 

 quently occurs in the lower types of human crania. The occipital 

 and right parietal bones thus need slight re-adjustment in the 

 published reconstruction (as described by Prof. Gr. Elliot Smith in 

 an appendix to this paper, p. 93), but the result does not alter 

 essentially any of the conclusions already reached. The only real 

 addition to our knowledge of the skull is made by the discovery of 

 the nasal bones. 



Like the cranial elements, the nasal bones are comparatively 

 stout ; and they are thickened at the upper border, suggesting 

 a massive and somewhat overhanging brow-ridge. They are so 

 well preserved that they fit perfectly at the median suture, and 

 show that they form a gently-rounded arch, constricted above 

 and widening below, but Avith scarcely any upturning at the lower 

 border (PI. XV, figs. 1 a-\ d). Both are narrower above than below, 

 and the bone of the right side is considerably wider in its upper 

 part than that of the left side. Below the irregular roughening at 

 the upper thickened end, the outer face of the bone is nearly smooth; 

 while the inner face of each is marked, as usual, with the longi- 

 tudinal groove for the nasal nerve (PL XT, figs. 1 c & 1 d, n.). The 

 left nasal (figs. 1 b & 1 c) is complete, and shows well the extension of 

 the infero-external angle, by which the slightly-concave, free lower 

 border of the bone is lengthened. The right nasal (PI. XV, fig. 1 d) 



1 That of Stegodon probably presented a more rolled appearance beforo it 

 was shattered.
