432 TUE EUCEXE PERIOD. 



acetabulum. A trace of aa anterior inner spine. Posterior edge at aceta- 

 bulum not expanded. Scissura acetabuli open. The ischia are shorter than 

 the ilia, and the shaft is flat, and the tuber not enlarged. There is an an- 

 gular spine. The base of the pubis is compressed. 



The head and great trochanter of the femur are distinct, and the latter 

 is as elevated as the former. It is excavated by a deep trochanteric fossa. 

 The little and third trochanters are prominent, the latter near the middle of 

 the shaft. The condyles are well separated. The rotular groove is not 

 short or wide, is well excavated, and the internal ridge is the most produced. 

 The tibia is not elongate, and has a large head. The crest is truncate 

 obliquely above. The distal extremity is small and robust, and the malleo- 

 lus is prominent. The astragalar grooves are not oblique. The fibula is 

 distinct throughout, and is rather stout. Its extremities are not much ex- 

 panded. 



The posterior foot was not plantigrade, but proportioned much as in 

 Tapirus, adding a digit on each side to the three possessed by that genus. 

 These digits are arranged in the arc of a circle, so as not to give unusual 

 width to the foot. The third is longer than the second and fourth, and the 

 fifth is longer than the first. The astragalus has much the form of that of 

 a carnivorous mammal. The lateral crests are well developed, and of une- 

 qual elevation, the external being the most elongated. The median groove 

 is wide and deep. The neck is distinct, and is rather long, and is bent 

 slightly inwards. The head is transversely oval, and its articular surface is 

 uniformly convex in all directions. The caleaneum is of average length, 

 and has a compressed shaft. It has no horizontal extension at the astraga- 

 lar condyle, and the sustentaculum is robust and short. The cuboid facet 

 is oblique towards the astr.agalus, with which it is about equally produced. 

 The navicular is a sim])le, short, saucer-shaped bone, much like that of the 

 carnivora. The ectocuneiform is robust, and has a prominent jiosterior 

 tuberosity. The mesocuneiform is shorter, and is transverse. The ento- 

 cuneiform is longer and narrower than the others. The cuboid is a robust 

 bone, with a large posterior tuberosity Its proximal extremity has l)utone 

 articular face, which is convex anteropostoriorly. The phalanges are not 

 shortened, and the ungues are well developed, flat, and obtusely angular.
