 irregular anterior border. The postfroutals are apparently small.

This specimen is closely allied in general form to D. jouberti. It 

 differs in the possession of a postfrontal which is apparently absent in 

 D. jo^tbert^ and in the elevated pineal foramen. It is probable, how- 

 ever, that the two species are closely allied.

Another specimen (Cat. No. 3034) from the type locality is about 

 four-fifths the size of the foregoing, and agrees with it in general 

 proportions. The eyes are moderately small and rounded. The pre- 

 parietal is of slightly different shape, being more regularly oval, 

 although still considerably longer than broad. Its relations with the 

 frontals, the parietals, and the pineal foramen are as in the larger 

 specimen.
