th;in the other, but the t\vo are of closely similar shape and proportions. 

 The larger (36O2) has a length of 600 mm. The breadth at the 

 proximal end, from the border of the caput femoris to the lateral 

 border is 175 mm. The proximal end is strongly rounded, and its 

 shape approximates closely to that of Plateosaunis erlenbergensis. The 

 upper end of the bone is 85 mm. thick, but it is compressed between 

 the upper surface and the trochanter major. At the trochanter major

it swells again, but not to such an extent as in Enskelesaurus. The 

 shaft is slightly S-shaped. 



The lower end of the ith trochanter lies 305 mm. below the top 

 of the bone. The trochanter is slightly curved, concave medially, 

 and lies nearer the medial than the lateral side of the bone. The 

 distal end is broadened and thickened. The medial condyle is consi- 

 derably larger than the lateral. Above the condyles on the hinder 

 face the intercondylar fossa is shallow and broad ; between the condyles 

 it is narrower and deeper. The medial condyle is a large rounded
