“Of the four digits in the manus all the phalanges are represented with 
the exception of the terminal one of digit II. As digits III, IV, and V 
ended distally in a hoof (or nail) carrying bone it is probable that digit II, 
the inner finger, bore a terminal hoof-phalanx also.” 
In Figure 6 the bones of the fore feet are shown in the position in which 
they were found, and as they are now in the mounted skeleton. They 
have been so little disturbed from their natural relationships that there 
appears to be no doubt of their proper arrangement in the manus which, 
it is believed, has been correctly interpreted by Lambe as shown in Figure 7, 
though his interpretation of the digits being uniformly spread is questioned. 
Figure 6. Fore feet of Thespesius edmontoni. Type, No. 8399, Geol. Surv., Can. Showing 
the position of the bones as found. Ra, radius; Ul, ulna; II, III, IV, and V, respective digits. One- 
tenth natural size. After Lambe.

Ra, radius; Ul, ulna; II, III, IV, and V, respective digits. One-tenth natural size. After Lambe. 
It appears to me from the evidence available that the articulated upper 
extremities, when viewed from above, would form an arc of a circle, and 
that digit V is probably more divergent than shown in Figure 7. This is 
demonstrated in the present specimen by the appressed arrangement of 
mtcs. II, III, and IV, whereas mtc. V is massive and less than half the 
length of mtc. IV.
