tliat of the shaft with which it is "continuous, is nearly flat. The narrow, 
prominent, anterior face of the shaft is continued obliquely into the malle¬ 
olus, while the posterior face exjoands gradually, and without irregularity, 
into the entire distal extremity. The ligamentous groove on the postero- 
interior asjDect could not have been large, although its precise character is 
obscured by injury of the surface of the bone. The astragalar face is more 
oblique transversely than in any of the genera of this group: the posterior 
margin is, as elsewhere, the most so; but the anterior is in no part trans¬ 
verse, as in Stypoloplnis. As in the other genera, it forms an angle with the 
malleolar surface, but a very open one. As usual, the strongest concavity 
of the astragalar face is next the malleolus. The external margin is nar¬ 
rowed and slightly recurved, not truncate as in StypoJophns. This tibia also 
differs strikingly from that of the latter genus in tlie absence of the postero¬ 
external longitudinal angle and the compression of the shaft. It differs 
from that of Oxycena in the absence of the exterior ridge, the posterior and 
interior tuberosities, and compression of the shaft. The distal part of the 
calcaneum is rather elongate and compressed. 
This species of Carnivore is of robust character, and about the size 
of the Jaguar.
