    the ilium ; but the posterior half is somewhat concavely exca- vated, as though it had contributed to the acetabulum. The surface which appears to be the articulation for the ischium is remarkably strong and irregularly four-sided, 2;^ inches deep, and wider above than below. It shows a carti- laginous surface, and may possibly have been connected with the ischium by a cartilage. The pubes appear to have been dii’ected downward and forv.'ard, and, as M. Fischer has stated, to have met in the median line; for at the transverse distal extremity along the inner margin an oblique articular surface extends over the bone, about an inch deep in the middle and rather narrower towards the inner and outer borders.

The pubis is constructed on the same plan as that of Massospondylus, but differs in having the obturator foramen or notch relatively smaller. The formation of the backwardly directed process above the obturator foramen is very similar in the pubes of Zanclodon., figured as sternum by Plieninger (Jahreshefte, Wiirtt. 1857, t. xi. fig. 1), in which the bone appears to retain the width of the plate from the distal end upward to the obturator notch. But in the Tiibingen speci- men, which I have referred to as Teratosaurus Quenstedti, there is no such development of a subacetabular process, and the acetabular notch is much larger. In Staganolepis the bone is apparently similar at the proximal end so far as the sub- acetabular process is concerned ; but these are the only genera known in which the pubis has a similarly expanded blade and a hook-like proximal end. I have no knowledge of the ischium or ilium. Vertebral Column. The only vertebrae of Euskelesaurus hitherto known are
