Maxilla, plate V, robust, high at the centre, sloping downward toward either end, 

 the dental chamber occupying nearly the whole of its length. Seen from above, the 

 posterior half slopes obliquely forward and outward, while the reverse is the case in 

 front ; at the extreme anterior end there is a limited slope inclined obliquely outward. 

 Also, viewed irom above, the posterior half is straight and broader than the front half 

 which narrows to a- rounded, outwardly turned point. Inner surface rather flat. Outer 

 surface with a rounded ridge running horizontally from the posterior end to meet the 

 facet for the articulation of the anterior end of the jugal. On the inner, upper side behind 

 mid-length, a facet, probably for the palatine, is present. Teeth replacing each other from 

 the inner side, apparently not more than two, of a series in v;se in the grinding surface at 

 the same time ; the carinated, enamelled faces of the crowns facing outward. A row of 

 foramina, similar to that of the lower jaw, conspicious in the upper part of the inner side. 

 Several large foramina occur in the anterior half of the outer side.

Pubis, plate X, fig. 1 (provisionally associated with T.marginatvs), produced forward 

 into a broad, thin, transversely compressed, spatulate expansion that is slightly concave 

 on its outer surface. Posteriorly a slender postpubic process, springing from a point 

 inside and in advance of the base of the pedestal bearing the ischiac facet, is directed 

 backward on the lower border of the ischium with which it effects a ligamental union.
