The ilium presents a stout tuberosity above the acetabulum on the 
outer edge of its anterior face, which is not seen in Didelpliys, Macropus^ 
HypsiprymuuSj Canis, uor Felis^ and is feebly present in Ursus. In all, it is 
the seat of origin of the rectus femoris muscle. The extero-anterior angle 
of the ilium maintains its distinctness from the intero-anterior, so far as the 
ilium is preserved, and does not run into the same plane as in Felis^ Canis, 
and Quadrumana; but it does not diverge from it so widely as in Bidelpliys, 
where its position gives the ilium a prismatic form. The form in the 
Stypolophus Mans is in this respect intermediate between DidelpMjs and 
Ursus. The sacral articular face commences but little beyond the line of 
the anterior-inferior spine, in which it resembles Ursus more than any other 
genus above mentioned. The ischio-acetabular groove is very strong, as 
in Canis and F)idelphys; it is weak in Ursus. The pubis is lost. 
The head of the femur presents a fossa ligamenti teris, connected with 
the border by a shallow groove. The remainder of the bone is lost. The 
head of the tibia presents a very large cnemial crest and a distinct spine. 
The facets for the femoral condyles are separated by the tendinous emar- 
gination. The external and posterior fossse are deeply excavated, and sepa¬ 
rated by the extero-posterior longitudinal ridge of the shaft. The distal 
end of the tibia presents characters like those of the other Creodonta. The 
inner malleolus is wide and produced, and the exterior extremity of the 
astragalar face is angular and recurved. The part of the anterior border 
of this face adjacent to the malleolus is at right angles to the latter, but all 
the other borders are oblique to it, especially the external parts of it. 
There is an external angle of the shaft rising from the external angle of the 
astragalar face, and there are no marked tuberosities around the borders
