clawphalanges, the articulation surface is divided by a vertical ridge into two 
parts, of which in this case the medial one is slightly broader in its lower end 
than the lateral one. Through the position of the distal articulation surface 
of the preceding phalanx, the clawphalanx must lie obliquely from above 
downwards and inwards. The clawphalanges of the second and third fingers 
are much less curved. The lateral groove for the claw is slightly higher than 
the medial one, although the difference in height is scarcely noticeable in the 
third clawphalanx.

A few millimetres are missing from the extreme end of the clawphalanx 
of the first finger. The length of its lower surface has been taken for the length 
of the ultimate phalanx of the fourth finger. 
Ileum. 
Both ilea are preserved, but they have suffered greatly from pressure. 
The ileum is a broad plate with a short spina anterior and a long spina pos- 
terior (PI. XIX, fig. 2) . The acetabulum cuts deep into the bone and is bordered 
in front by a long processus praeacetabularis and behind by a short processus 
postacetabularis. The upper portion of the ileum is thin, the lower portion 
thicker. Both spina anterior and posterior are directed outwards and the 
outer surface of the bone is therefore concave. The length of the bone from 
the spina iliaca anterior to the spina posterior is 19-9 cm. in the left and nearly 
21 cm. in the right ileum. The upper border, which is damaged, is convex. 
The outer surface of both spinae and of the upper border as far as preserved 
is coarse, and has apparently served for the attachment of muscles. This 
coarse surface is especially large on the spina posterior. The hinder end of 
the spina posterior is truncated. Nothing can be said of the medial surface 
of the bone, for in both cases it is covered by matrix and other bone material, 
which could not be removed. The height of the ileum, from the processus
