though very much damaged, the trochanter quartus is still recognisable. As 
preserved, the distance of its upper end from the proximal end of the bone 
is 41 mm. In the perfect specimen this distance may have been 2 or 3 mm. 
shorter. The trochanter is too much damaged to measure its length. It is 
situated much closer to the medial than to the lateral side. The lower end of 
the trochanter is further away from the medial side than the upper end. The 
fossa intercondyloidea is not visible. The anterior surface of the distal end is 
slightly concave in the middle. The border of the bone between the anterior 
surface and the distal surface is also slightly concave. The length (antero- 
posterior measurement) of what may be the condylus lateralis, measured from 
the anterior surface to the extreme tip of the condylus, is 33 mm. The section 
through the distal surface shown by the right femur does not show any 
obliquity to the axis of the bone ; only the posterior end of this line is slightly 
elevated. The breadth of the distal end is 28 mm. The shaft of the femur 
has a minimum breadth of 17 mm. in the middle. The minimum thickness of 
the bone is 16 mm., also in the middle. As seen from behind the femur is 
straight, but the lateral view of the right femur shows a pronounced sigmoidal 
shape. 
Tibia. 
Both tibiae are preserved, but the surface of the bones is badly damaged. 
They both show their medial side. The proximal end is very large and the 
shaft, as seen sideways, is straight. The length of the left tibia (see fig. 6) is 
126 mm. ; that of the right one 129 mm. The length of the head is 36 mm. in 
the left and 38 mm. in the right tibia. The line of the proximal surface, which 
passes from behind upwards and forwards, curves gradually into the line of 
the anterior surface in the left tibia. In the right one, which is plainly damaged 
at this point, these two lines meet at an acute angle. Considering both bones, 
it seems that the tuberositas tibiae did not protrude much. Distally the 
proximal end becomes rapidly thinner and passes into the shaft. No thick- 
ening is visible of the distal end. The medial border of the distal surface is 
straight and at right angles to the shaft. The thickness of the distal end of 
both bones is 15 mm. The thickness of the shaft remains practically the same 
as that of the distal end till past its middle, where the shaft becomes gradually 
thicker towards the proximal end. The line of the anterior surface of the bone 
is very slightly concave and the line of the posterior surface is strongly concave 
in its proximal half. 
Fibula. 
Only the right fibula is visible. It is seen from the front, but its whole 
surface is very much damaged. Its length is 122 mm. The bone is slightly 
convex outwards. The breadth of the bone in the middle is 7 mm. and at its 
lower end 17 mm. The proximal end is partly covered by the tibia. The line 
of the distal surface is at right angles to the line of the lateral surface. 
Tarsalia. 
The right tarsus is complete and remains of the left one are also present. 
Of course all the bones are flattened and only show one side. 
The astragalus of the right foot has a length of 29 mm. and a breadth of 
12 mm. It shows probably its upper surface, but this has only partly been 
preserved. Its hinder border is thin. The upper surface is divided into three 
concave portions by two feeble ridges, which start at the front border, about 
8 mm. apart and diverge backwards.
