venous foramina of the distal co-ossified cervicals are in pairs, and of large 

 size. In the proximal caudals, the diapophyses are above the middle of the 

 sides of the centra. In one, the basis of a chevron is preserved. It is 

 cylindric and striate. The zygapophysis on the hinder aspect of a dorsal has 

 a disciform articular surface directed outward and downward ; the prominence 

 of its upper face is continuous with the lateral ridge of the neural spine. 

 The anterior up-looking surface is equally small and little divergent.

It may be observed that the anterior caudals have a nearly round articu- 

 lar extremity ; one of them is a little wider than high, but they are too much 

 distorted to furnish reliable measurements. 



The portion of the ilium preserved is an extremity. It is flat on one side 

 and convex on the other. The shaft is solid. The articular extremity is 

 oblique in one direction and truncate in the other, which is at right angles to 

 a short, recurved margin, which has been an insertion or articulation ; the flat 

 surface is rugose distally. Long diameter of extremity, 2.75 inches ; of shaft,- 

 1.9 inches. The articular faces of the extremity of the femur are at an open 

 angle with each other, and are strongly concave in transverse section. The 

 femur is here very flat, with narrow margins ; it becomes stouter with dimin- 

 ishing width. Distally, the surface is marked by grooves and small foramina. 

 What may be tibia is the basal frustum of a wedge ; the articular faces are 

 broad; the outer margin narrowed ; the faces slightly concave. The inner 

 margin is shorter than the outer, and the distal part of it presents a broad 

 articular face. Some of the tarsal bones have been already described. There 

 are thirteen metatarsals and phalanges. They are of stout proportions and
