Its humeral glenoid face is more convex transversely in its anterior or 

 vertical portion than in those genera, and a little more than in Ursus. 

 In the hind limb the femur resembles that of other Carnivora in all 

 essentials. The rotular groove is narrow and elevated, the inner margin 

 a little higher. The condyles are rather narrow, the inner with less 

 transverse and antero-posterior extent, and separated by a wide and 

 deep fossa. The patella is narrow, thick, and truncate at one end. The 

 proximal end of the tibia exhibits a very prominent and well elevated 

 crest or spine, which bounds a deeply excavated fossa. The articu- 

 lar faces are separated by a deep notch behind ; the external is a 

 little the larger and is produced into a point outwards and backwards ; 

 it lacks the notch of the antero-exterior margin so distinct in Canis, but 

 possesses an emargination at the outer base of the crest homologous 

 with it. The general form is, however, more like that of Canis than of 

 Fells, and least like that of Ursus. The distal extremity of the tibia 

 presents Carnivorous characters. The two trochlear fossae are deeply 

 impressed, the outer wall of the external one being formed by the fibula 

 only. The anterior marginal crest is more elevated than the posterior, 

 and presents an overlapping articular face between the fossa) for a cor- 

 responding tuberosity of the neck of the astragalus. The inner malleolus 

 is entirely without the groove for the tendon of the tibialis posticus 

 muscle, and therefore different from many of the digitigrade Carnivora. 

 It has an ovate truncate surface. On the anterior face opposite the 

 inner trochlear groove is a rather small but deep fossa. 



The astragalus has an elongate oblique neck and a navicular extremity 

 slightly expanded inwards. The trochlear ridges are well elevated, and 

 not very oblique to the true vertical plane, being much as in the dog. 

 The distal extremity is quite different from Felis, Hycena, Canis and 

 Ursus in having a rather narrow convex facet next the cuboid bone ex- 

 tending from front to rear, and in having the navicular facet pulley-like 

 or slightly concave in transverse section, while it is strongly convex 

 antero-posteriorly. This is part of the peculiarity presented by the 

 hind foot in this genus. Behind the navicular facet, on the superior 

 face, is a tuberosity which stops the flexure of the foot by contact with 

 the tibia ; a trace of it is seen in the dog. The calcaneum has the com- 

 pressed form of the digitigrades, but the broader interval, and convex 

 external astragaline facets resemble much more those in the bears. The 

 cuboid facet is a frustrum of a triangle with the apex directed inwards 

 and downwards. 



The metapodial bones are rather elongate, and flattened so as to be 

 transverse in position. A second metatarsal is more flattened than 

 corresponding bones of Canis and Felis. Its cuneiform facet is some- 

 what concave transversely. The phalangeal condyles are furnished with 

 an anterior and inferior carina, which is wanting above ; the articular 

 face is wide above as in Canis, and is bounded by a transverse fossa as 

 in digitigrade genera. The phalanges of the first series are elongate
