DESCRIPTION OF THE LIMBS

while the magnum behind is in contact with the scaphoid, lunar, and cuneiform. 
The massive posterior portion of the lunar bears a prominent mass of bone 
projecting behind the articular facet for the magnum. 
The dimensions of the lunar are : 
mm. 
Greatest width from before back . . . . . . . . . . 175 
Greatest width radial facet from before back . . . . . . 133 
Greatest width radial facet from side to side . . . . . . 134 
Greatest depth of anterior face . . . . . . . . . . 94 
Greatest width of anterior face from side to side . . . . . . 158 
The Cuneiform (PI. IV, fig. id). — No specimen of this bone was found with 
the Upnor skeleton. The British Museum collection contains a large imperfect 
fore-foot from Grays, probably belonging to E. antiquus, and of about the same 
size as our specimen ; the cuneiform and unciform (both regd. 18246) of this foot 
have been used in making the restoration of the fore-foot for the mounted skeleton. 
The Pisiform (PI. IV, fig. 2). — The pisiform is a strongly curved bone 
terminating distally in a roughened tuberosity. The facet for the ulna is very 
small and narrow, and it makes an oblique angle with the facet for the cuneiform. 
This tongue-shaped surface is long, extending over nearly a third of the length of 
the bone. The form and arrangement of the facets is very unlike what is seen in 
E. antiquus vecki, E. maximus, and E. africanus, but is somewhat similar to what 
occurs in the pisiform of a Mammoth from Klinge figured by Dietrich (1916, pi. v, 
fig- 8)- 
The dimensions of the pisiform are : 
mm. 
Greatest length . . . . . . . . . . . . . . . . 188 
Greatest width at upper end . . . . . , . . . . . . 9 7 
Greatest length of the facet for the cuneiform . . . . . . 90 
The Trapezium (PL IV, fig. 3«).— This bone is preserved on both sides, but 
that from the right is in much the better condition of the two. The angle between 
the facets for the trapezoid (tz.) and for the second metacarpal (me. 2) is a very 
obtuse one, so that they are not far from lying in the same plane. In E. maximus 
this angle is only a little greater than a right angle ; in E. africanus it is more 
obtuse, but not so much as in our specimen. The facet for the scaphoid is smaller 
than that for the second metacarpal, and it makes about a right angle with the 
facet for the trapezoid. The distal articulation for the first metacarpal is oval 
and slightly convex ; in E. africanus it is nearly flat. In E. antiquus recki the 
whole bone seems to be proportionately shorter and stouter. 
The dimensions of the trapezium are :
