diameter is about 3 mm. and the distance from the scapular border is between 
2 and 3 mm. 
Humerus. 
Both humeri are present. Their proximal ends are fairly well preserved, 
but their distal ends are poor. The very broad proximal end is hollow in front 
and convex behind. Its upper border is convex and its upper-lateral border 
slightly so. There is no distinct demarcation between the upper end of the 
processus lateralis and the upper border of the bone. The lateral border of 
the humerus is strongly concave immediately below the processus lateralis. 
The medial border of the proximal end is concave throughout. There are 
indications that the caput humeri was not situated on the extreme medial 
end of the upper border. The breadth of the proximal end, measured from 
the lower corner of the processus lateralis to the upper medial end, is 45 mm. 
in the left and 52 mm. in the right humerus. 
The shaft is very narrow; at its narrowest place it measures 9 mm. in the 
left humerus. All that can be said of the distal end is, that the condyli project 
forwards and do not make themselves apparent on the hinder surface. The 
length of the humerus differs considerably in the two specimens. The right 
humerus measures 93 mm. in length and the left only 80 mm. The length of 
the left humerus is most probably reduced by crushing, as it stands nearly 
vertically on the general plane of the remains. The lower end of the processus 
lateralis lies 53 mm. above the distal end in the left humerus and 58 mm. in 
the right one. 
Ulna and Radius. 
There is not much left of these two bones. Only those of the right side 
have been preserved and these are really nothing more than impressions. The 
proximal end of the ulna is broad. The line marking its articulation surface 
is not perpendicular to the axis of the bone, and therefore, what is most 
probably the hinder portion of this end, is higher than the front portion. The 
breadth of this end of the impression is 18 mm. (this would in reality be the 
thickness of the bone). Distally this dimension is gradually reduced towards 
the middle of the shaft, which has a breadth of 9 mm. Then the breadth 
increases again towards the distal end, which may have been as broad as the 
proximal end. The total length of the bone is 64 mm. 
The impression of the radius has a proximal breadth of 10 mm. and a 
distal breadth of 14 mm., while the shaft has a breadth of 8 mm. The total 
length of the bone is 58 mm. The line marking the proximal end of the im- 
pression seems to be concave, so that probably the proximal articulation 
surface was hollow, at least near the side which made the impression. 
Carpus. 
The remains of probably four carpalia are present and still in their original 
position, but they are so fragmentary that nothing can be said about them. 
Ileum. 
Both ilea are present. The left ileum is visible from the medial side. Its 
contour is complete, but most of the surface of the bone has broken off and 
portions of the upper part of the bone are only represented by impression. 
The right ilehm is badly preserved. It is visible from the ventral side and its 
position is more or less vertical to the plane of the remains. Therefore it has 
suffered greatly from crushing; 
The ileum consists of a large plate, which is slightly longitudinally convex 
as seen from the medial side, and which has a short anterior and a long pos-
