AKTIODACTYLA. 723 



The centrum of the lumbar vertebra is much depressed, and the base 

 of the diapophysis occupies its entire length. The latter is slightly 

 decurved and directed posteriorly, and its base is concave below. The 

 inferior face of the centrum is not excavated, and is weakly keeled me- 

 dially. The form of the ilium is peculiar, differing from that of most of 

 the Artiodactyle animals with which I have compared it. The rather wide 

 concave anterior face at the inferior part of the peduncle is due to the 

 prominence of the anterior edge, and of a crest on the inner side. The 

 former is prominent just above the usual position of an anterior inferior 

 spine, and then sinks to the edge of the acetabulum. The internal face is 

 narrower than the external, but wider than the anterior. I do not find the 

 anterior face among any of the Ruminantia, except in a modified degree in 

 Antilocapra, nor in any of the Omnivora, excepting in the Phacochcerus^ 

 where it is not so concave. The peduncle is shorter than in Tragulus, and 

 wider than in any of the Suillines or Ruminants which I arn acquainted with. 



The external face of the great trochanter of the femur is wide. Its apex 

 is a little incurved, and projects further than the head. The neck is deeply 

 constricted from above. The little trochanter is quite prominent. The 

 head is round, and the fossa ligamenti teris, though behind the middle of its 

 inner aspect, looks directly inwards. The external edge of the shaft of the 

 femur is acute; the inner edge is rounded. The rotular groove is rather 

 narrow, and is on an elevated base. Of the lateral crests, one is a little 

 higher than the other near the proximal end. The internal, posterior, and 

 external faces of tha distal extremity of the tibia are flat, the last two sides 

 separated by an angle. The internal face exhibits a shallow tendinous 

 groove. The calcaneum has a wide longitudinal concavity of the external 

 side. It is bounded above by a low ridge, which disappears below the 

 fibular condyle. The cuboid face is oblique vertically and transversely, 

 and is contracted in extent. The external face of the cuboid has a prox- 

 imal concavity and a distal tuberosity running downwards and posteriorly. 

 The external face of the fibula has a ridge which terminates abruptly a 

 short distance above the distal extremity of the bone.
