OSTEOLOGY OF E. DOLLOVIANUS, COPE 



comparison with the figure of the interclavicle published by 

 Cope (2), PL III, Fig. 5, it would seem that there were strong 

 radial processes. The length of the bone was about 0.31-32", 

 and the width of the expanded exterior end about 0.120"". 



In Fig. 6 is shown in 

 diagrammatic manner the 

 shoulder girdle with bones 

 in their proper positions. 



The fore limb. — The hu- 

 merus and radius conform 

 very closely in size and shape 

 with the same bones of Di- 

 ■metrodon ; see (i), PI. Ill, 

 Figs. 32 and 33. The ulna 

 is represented by the proximal end only, but this is quite differ- 

 ent from the ulna of Dimetrodon. Compare Fig. 7 with (i), PI. 

 Ill, Figs. 34 and 35. The olecranon fossa is more widel}^ open.

and the whole bone is more clumsy and less finely moulded — 

 a remark which may apply to all the bones of the skeleton in a 

 general way. 



Length of the humerus 0.191'" 



Width lower end humerus - 0.103 



The front foot of the left side is nearly perfectly preserved.
