larger proportionately tlian in tlie other Hysenas; it measured about 

 25 mm. across at its root, and its hinder border is separated from the 

 small round alyeolus(diameter 6 mm.) for p.m. 1 by an interval of 8 mm. 

 P.m. 2 is separated from p.m. 1 by a space of about 4 mm. ; it differs 

 from p.m. 2 in IT. brevirostris, with which it is comparable in size, 

 in not having the cingulum developed on its anterior or external 

 faces, and in the much smaller size of its posterior accessory cusp ; 

 the tooth is also less convex on its outer face. P.m. 3 is sinnlar in 

 most respects to that of H^. brevirostris, but narrows more towards its 

 posterior end where it has a larger accessory cusp. The long axes 

 of these two teeth are in the same straight line. P.m. 4 (the 

 carnassial) is much like that of II. brevirostris, having a well- 

 developed inner cusp (protocone), which distinguishes it from the 

 contemporary H. exivria. In II. gigantea, Schlosser, ' a large Hycena

from a bed of similar age in China, there is only a greatly reduced 

 inner cusp in p.m. 4. M. 1 is represented by its outer root only, 

 but was probably of considerable size as in 3^. brevirostris, and much 

 larger than in H. crocuta, where it is very small or even wanting.

As will be seen from the above measurements, this very large 

 species is comparable in size with Ilymia brevirostris, Aymard, and
