surface has been completely destroyed. The 4th digit is apparently 

 complete and uninjured, but has only three phalanges, and the last 

 is rudimentary and had no claw. The 5th digit in both feet has 

 only two phalanges. 



The digital formula for the manus would thus be 2, 3, 4, 3, 2. 



The following are the measurements of the bones of the 4th and 

 5th digits the former taken from the left and the latter from the 

 right foot :

The pelvis is fairly well preserved, but a little distorted. The 

 pubes and ischia of both sides are complete, and the greater part of 

 both ilia are present. In fact, the only part that requires to be 

 restored is the tip of the anterior process of the iliac crest. The 

 right ilium has the base of the anterior process preserved, and 

 the left ilium the greater part of the iliac crest ; so that the small 

 missing part can be restored with much probability. 



The iliac crest is much straighter than in Plateosaiirus or 

 T&ratosaurus, and the anterior iliac spine is unusually small. The 

 acetabulum is large, and the portions of the ilium which form both 

 its anterior and posterior walls are well developed. 



The pubes and the ischia form a complete symphysis, with no 

 opening of any sort in it from the front of the pubis to the posterior 

 end of the ischium. The upper end of the pubis is large and fairly 

 flat and forms a wide angle with its neighbour. It has a large 

 nearly round pubic foramen. The anterior portion of the pubis 

 is broad and flat, the two together at their narrowest part 

 measuring 122 mm. across. The greatest length of the pubis 

 435 mm. 



The ischium is rather shorter than the pubis. In general shape 

 it fairly resembles that of Sellosaurus and Plateosaurus. Its anterior 

 part has a long articulation with the pubis extending from the 

 acetabulum to the symphysis. The greatest length of the ischium 

 is 405 mm. The greatest measurement across the two ischia where
