DESCRIPTION OF THE LIMBS 
!7 
In E. antiquus recki the cuboid seems to be narrower from side to side in 
proportion to its antero-posterior diameter, and the long axis of the calcaneal and 
navicular facets are nearly parallel instead of converging posteriorly. 
The distal facets for the fourth and fifth metatarsals are more nearly similar 
to the same surfaces in E. maximus than in E. afvicanus. This is especially notice- 
able in the surface for the fourth ; in E. africanus this is separated posteriorly from 
that for the fifth metatarsal by a deep pit, not seen in E. antiquus or E. maximus. 
The dimensions of the cuboid are : 
Length of outer (volar) border 
Length of cuneiform border . 
Length of osterior border 
Greatest depth of anterior face

The Entocuneiform.— This bone is known Jrom the right side only. At its 
upper end it has an oval, nearly flat surface, looking upwards and backwards, for 
the navicular. On the posterior face of the bone beneath the navicular facet is a 
surface for the mesocuneiform, and there was probably also a distal facet on the 
inner side for contact with the second metatarsal. Beneath the proximal articulation 
the bone widens out and bears a tuberous prominence on both its anterior and posterior 
borders. Distally it then narrows and terminates in a gently convex, nearly circular 
facet for the first metacarpal, there having apparently been a well-developed hallux.

The facets are too much abraded to measure. 
Mesocuneiform. — No specimen of this bone was found. 
Ectocuneiform. — This bone is most similar to that of E. africanus. It is 
chiefly remarkable for the large size of the rectangular facet for the upper end of 
the fourth metatarsal. In E. africanus this facet is much smaller, and in E. maximus 
very small indeed (PI. VIII, figs. 3 a, 3 b, 3c). 
The upper surface for the navicular is gently concave from before backwards 
as usual ; it is much more elongated from before backwards than in E. antiquus 
recki. 
The dimensions of this bone are :

Greatest antero-posterior diameter . . . . . . . . . . 137 
Length of anterior face . . . . . . . . . . . . 93 
Depth of anterior face . . . . . . . . . . . . . . 54 
The Metatarsals. — The first metatarsal is not preserved on either side, but 
judging from the distal facet on the ectocuneiform it must have been of fairly large 
size.
