* The degrees of inclination of the fossa are not given for this species because the tem- 
poro-mandibular articulation of this animal has no tuberculum articulare; consequently, 
the determination of the degree of inclination of the fossa would be of no value Ln this 
relation. 
t The occipital bone including the occipital foramen were lost from these specimens, 
so that the angle of inclination of the fossa, the articular basio-nasal angle, and gnathic 
and dental indices could not be determined. The average values for each of these angles, 
therefore, were obtained from seven other specimens.
