From Dicynodon lutriceps this type seems to differ in having the 

 intertemporal width greater than the interorbital, in not having the 

 parietals so fully covered by the postorbitals, in the position of the pineal 

 foramen, and in the size of the preparietal. 



The form is also strongly reminiscent of D. mustoi ; but the latter 

 is somewhat more slenderly built, the pineal foramen is further 

 forward, and the postfrontal is a much larger bone. 



The chief resemblance, however, is to Owen's Oudenodon laini, as 

 far as can be judged from the figure of the latter. The two agree in 

 general shape, in the relation between the interorbital and inter- 

 temporal width, and in the position of the pineal foramen. The species

Oudenodon laini cannot, however, stand. In the first place, we know 

 that Oudenodon is but the female of Dicynodon ; Owen had previously 

 described another specimen as the type of Dicynodon baini ; and, 

 lastly, Dicynodon baini is but a synonym for D. tigriceps.
