leading forward from the supra-orbital foramen, and 

 extending ventro-laterally to the infra-orbital foramen 

 (this is probably a variable character) ; malar below 

 orbit as robust as in M. culbertsonii; sagittal crest and 

 postorbital processes of frontals very rugose.

Holotype. One lialf supe- 



The skull is fully adult and not crushed, although the 

 teeth are damaged. The distal end of the radius shows 

 that the facets for the scaphoid and lunar bones were 

 separated by a space of a little over 1 mm., which is an 

 unusually large interval in this genus.
