What I suppose to be the posterior end of the maxillary bone exhibits 

 the grooves to near its apex as well as a considerable surface of articulation 

 for the malar. 



Two dorsal vertebra are preserved, whose neural arches are coossified, 

 with a trace of the suture remaining. Both articular faces exhibit a transverse 

 fossa for ligamentous or bursary attachment. Round these, on the convex 

 face, there are transverse rugosities, while oblicpie-ridged lines descend on 

 each side from the floor of the neural canal. The centra are shorter than 

 deep, and subquadrate in a horizontal section. The sides are concave ; the 

 anterior one compressed with lenticular vertical section with the angle below. 

 The more posterior is less compressed, and the surface is smooth ; in the an- 

 terior, it is thrown into weak longitudinal ridges near the edges of the articular 

 extremities. There are large nutritious foramina on the sides. The neura- 

 pophyses are excavated vertically on their posterior edges. Neural canal on 

 the anterior dorsal, a broad vertical oval. A caudal vertebra is rather elongate 

 and depressed. ; as it has no cliapophysis, it is not from the anterior part of the 

 series. There is no prominent lateral angle, but the two inferior angles con- 

 necting the chevron-facets are well marked. Neurapophysis only measuring 

 half the length of the centrum. The articular faces exhibit the same trans- 

 verse fossa as is seen in the dorsals. The anterior is plane, the posterior 



reniformly concave.

The femur is only represented by the distal end, with the condyles per- 

 fectly preserved. The latter form a single trochlear surface, whose borders 

 form arcs of circles. It is slightly hour-glass-shaped, chiefly by excavation 

 of the posterior face, which is, however, shallow, the deep fossae seen in
