classed by Dr Scott with Cryptoprocta in a separate family, but is 

 now placed by him in the Nimravidce. The formula of the cheek- 

 's 1 

 teeth is Pm. -, M. -; the upper carnassial has no anterior lobe ;

the alisphenoid canal is retained ; the femur has a third trochanter ; 

 the astragalus is flattened and articulates with the cuboid ; and the 

 terminal phalangeals, although retractile, are not protected by bony 

 sheaths. Generalised features are also displayed in the base of the 

 skull ; and the bones of the skeleton approximate to those of Oyno- 

 dictis and other primitive types. 



Of the other generalised forms which may perhaps be included in 

 this family we may mention ALluropsis of the Pliocene of the Siwalik 

 Hills, and Pseudcehirns typically from the Middle Miocene, but re- 

 corded by Dr Filhol from the Upper Eocene Phosphorites of France. 

 sEluropsis is very imperfectly known, but its mandible seems to 

 approach that of the Machaerodonts. Dr Schlosser would include in 

 this genus some of the forms from the French Phosphorites referred

by Dr Filhol to Procelurus, and would change the name to Haplo- 

 ga/e, and place it in the Mustelidce. The typical Pseudtzlums has 

 three lower premolars, and no inner cusp to the lower carnassial ; 

 but in P. intermedins, which Dr Schlosser makes the type of the 

 genus Stenoga/e, there were four lower premolars in some instances,
