drawing of Broom’s restoration, slightly modified according to 
Osborn; z. ¢., the bone marked centrale 2 was called by Broom radiale. 
It will be seen that the carpus is essentially the same if the radiale is 
restored. The fifth carpal is missing, but that may well be left open 
for future evidence, as there is so commonly a fifth carpal in the 
primitive reptiles.
