The ilia are flat, and not very wide. The superior edge expands 

 rather abruptly at the neck, and then follows a curve nearly parallel with 

 that of the anterior border. The external face of the expansion is concave. 

 The anterior apex of the crest is subacute and decurved. It is robust and 

 subtriangular in section at base. Just above the position of an anterior 

 inferior spine, and near the edge of the acetabulum, is a deeply impressed 

 subtriangular fossa. The obturator foramen is very large. The anterior 

 edge of the ilium is much thickened and for most of its length is one-third 

 the transverse diameter of the plate The plate is abruptly thinner above 

 this line. The internal face of the innominatum is concave behind the 

 acetabulum, and the posterior edge is thickened and reverted at this point. 

 The inner face of the ischium is flat; the plane of its distal portion is 

 nearly at right angles to that of the plate of the ilium. The position of 

 the tuber ischii is but little thickened, and is very little curved outwards. 

 It is less prominent distally than the inner part of the posterior border. 

 The entire ischium is rather thin. The external face of its shaft is convex 

 near the obturator foramen.

The femur is a rather stout bone, rather more robust than that of the 

 Tapirus ierrestris. That is, it is shorter, but of equal diameter, and with
