b. Antero-superognathal 

 (PI. 27, fig. 7) 



E 1946 A small left antero-superognathal which differs from all 

 other specimens of this element known to us. It con- 

 sists of a single small but powerful cusp. There is no 

 secondary cusp. The element is well shown in the figure 

 in Plate 27. There is no doubt that it belongs to an 

 Arthrodire, but we are unable definitely to assign it to 

 Dinichthys or to any other genus.
