of the back, loins, and tail, bones of the fore-limb and of the hind- 

 limb, for the most part in remarkable perfection. They present 

 some difficulty. Teeth of Megalosaurus Bucklandi well charac- 

 terized were scattered in confusion through the mass, and still 

 remain attached to some portions. The portions of jaws found 

 are also megalosaurian, one specimen being the anterior portion 

 of one ramus of the lower jaw, much like that in the Oxford 

 Museum, another being a pair of intermaxillary bones, with four 

 tooth-sockets on each side, a tooth remaining in one.

 Upper figure, a side view ; left-hand figure, from above ; right-hand, from below. 



The fore-limb bones are one incomplete humerus, considerable 

 portions of radius and ulna, and two phalangal bones. Of the 

 hind-limb, a pair of femora complete, with a long spirally-ridged 

 pubis laid by each; a pair of tibiae, each having portions of a 

 fibula near it, in one case almost the complete bone slightly dis- 

 placed; an astragalus to match each tibia, in one case so placed 

 as to justify the approximation originally suggested by Cuvier 

 (see Diagram LXIV., #); five nearly complete and three broken 

 metatarsals, several phalanges, and one claw-bone. 



A nearly complete ilium of the general pattern of megalosaurus, 

 and specially like the smaller one represented in Diagram LXVII. 



All the bones mentioned are in point of magnitude about half the 

 size (linear) of the largest megalosaurian bones of Stonesfield, and 

 in relative proportions they are much in agreement with them. 

 On comparing the bones of the hind and fore limbs, the former
