species Lutra bathygnathius. To the bears he adds Ursus the 
baldi, which may probably be the ancestor of the aswail (U. labis- 
tus), but had better developed molars. Ayenarctos punjabensis 
and H. paleindicus are considered to be distinct from H, stvalensis; 
Amphicyon paiwindicus is added to the Canide and Viverra du- 
randi, the largest known civet, to the Viverrideæ ; Hyena colvini is 
separated from Æ. sivalensis, and is said to approach Crocuta, and 
H. macrostoma constitutes an important link between the more 
typical members of the genus and the viverroid and canoid Car- 
nivora. To the Felidæ are added Æ/uropsis annectans, and Felis 
brachygnathus and the occurrence of a hyænodon (H. indicus) in 
the Siwaliks is mentioned as a matter of extreme interest ——M. 
Lemoine (Bull. de la Soc. Geol. dè France, 1883), describes Mw- 
plagiaulax eocenus and N. marshit, from the Lower Eocene neat 
Rheims. The genus is distinguished from Plagiaulax by the 
presence of a single premolar only on each side. M. Lemoine 
considers it as intermediate between Plagiaulax and the recent 
Bettongia. ,
