size, being intermediate between the Tennocyon corypJiceus and the Galecynus 

 geismarianus in this respect. Secondly, it may be known by the depression 

 of the face at the orbits and the prominence of the anterior part of the malar 

 bone. 



Laid by the side of the skull of T. coryphaeus so that the posterior 

 borders of the second tuberculars of this species and that one are in line, 

 the canine of T. josephi originates in line with the posterior border of the 

 first premolar of the T. coryphaeus. Of course the molars are absolutely 

 smaller in T. josephi, but the sectorial is also relatively smaller. In T. 

 coryphaeus the length of that tooth exceeds the space occupied by the first 

 and second premolars; in T. josephi its length is considerably less. The 

 third premolar of the T. josejihi lacks the posterior tubercle found in the 

 T. coryphaeus, but a small basal heel is present. There is a narrow internal 

 basal cingulum of the superior sectorial. The first tubercular is not so 

 oblique as in T. waUovianus, and has an external cingulum. It has a strong 

 V-shaped crest within the middle, which is well separated from both the 

 external tubercles and the internal cingular border. 



The inferior position of the orbit is indicated by the fact that the dis- 

 tance from its inferior border to the base of the sectorial measures one-half 

 the distance between the anterior border of the sectorial and the posterior 

 border of the canine. In T. coryphaeus it is three-quarters, and in T. geis- 

 marianus it is three-fifths that distance.
