(66.0) ; greatest breadth of both nasals together, 23.6 (20.6); mandible, 

 159.4 (162.0); maxillary toothrow, (12.2 ((14.0); mandibular toothrow, 

 64.0 (68.0). 



Remarks. — The differences in size are clearly shown both by the actual 

 measurements of the individual teeth, and by the area of the crown con- 

 sidered as a parallelogram. In the following table the teeth of the two 

 specimens of Rupicapra fzesula are compared with those of three adult 

 males of R. rupicapra (the largest in the collection) and an adult male 

 of R. pi/renaica.

The teeth are relatively as well as actually larger than in Rupicapra 

 rupicapra. In two adult males of the former the ratio of upper toothrow 

 to condylobasal length of skull is 29.1 and 30.5. In the two males of R.
