The femur has a strongly curved shaft. The inner trochanter lies 
wholly on the proximal half of the shaft, and is compressed. Unfortu- 
nately it is incomplete, so that it is impossible to say whether it was 
of the pendent type characteristic of Camptosaurits or of the type seen in 
Iguanodon. The slender evidence available leads to the belief that it was 
not of the pendent type. Just in front of the trochanter on the inner side 
of the bone is a shallow depression with a rugose surface. The head 
is well developed and globular, and well seen in specimens 2731a and 
2731d. Between the head and the remainder of the articular surface 
is a well-marked shallow groove. A lesser trochanter rises on the antero- 
external surface of the shaft, nearly to the height of the greater trochanter. 
It is compressed transversely, and, in all the specimens, owing to crushing, 
it is compressed on to the shaft. Before compression it must have been 
separated from the shaft posteriorly by a deep and narrow cleft. In the 
posterior upper surface of the shaft are two concave depressions, separated 
above by a prominent wide ridge. The inner of the grooves is just behind 
the head. The distal end shows the usual two condyles. The inner 
condyle is more robust than the other. Both have rugose articular 
surfaces. The anterior intercondylar groove is wide and shallow as in 
Camptosaurus. The posterior groove is deep and fairly wide, its shape 
being best understood from the outline figure given. The femoral remains 
show the presence of at least three, and possibly four, distinct individuals, 
but there is no doubt that they are all of the same species. 
Only the proximal and distal ends of a tibia are present, so that it is 
impossible to give the relative lengths of the femur and tibia. The 
proximal end is very robust. The two condyles project posteriorly and 
are separated by an intercondylar groove. Of the two, the inner one is the 
larger and projects further back. The cnemial crest is very large and 
projects outwards in front of the external condyle from the top of the 
shaft. The broken end shows the proximal portion of the shaft to have 
been oval in cross-section, the longer diameter running in an antero-pos- 
terior direction. The distal end (2731^) of what is probably the same left 
tibia shows the usual malleoli, the outer being more slender and longer 
than the inner. They are separated on the anterior surface of the bone 
by a wide and shallow depression. 
The astragalus, calcaneum, one tarsal, and the proximal ends of three 
metatarsals are all present in the specimen 273iy, but as far as displayed 
call for no special comment. 
Specimen 2731/ shows two posterior caudal vertebrae and portions of 
two others. The neural spines pass back behind the level of the front 
of the next succeeding centrum. The anterior zygapophyses are finger- 
like processes which pass forward along the base of the neural spine 
of the preceding vertebra. No chevrons are displayed.
