The anterior limh is unknown. Of the posterior we have femora 

 in sufficient number and good preservation. It is, like the cor- 

 responding bone in the crocodiles, sigmoidally bent, with a com- 

 pletely-rounded head, which, seen endways, has a rhomboidal 

 outline, with diagonals 2*0 and i -4. On the inner face a prominent 

 boss, much as in steneosaurus, extends the spheroidal surface of

the head. No distinct trochanterial tubercle on the outer and lower 

 part of the bone. Capitular end strongly ridged. The distal 

 extremity is always found to be of compressed form and rounded 

 outline, with but faint marks of the condyles much as Cuvier 

 represents the bone in the Caen fossil. It is usually eleven inches 

 long, with diameters in the smallest part of 0-9 and 0*7 ; but some 

 specimens must have been fourteen or fifteen. There is ground for 

 distinguishing two forms; one less sigmoidal, and much more 

 slender toward the distal part of the bone. 



One metatarsal bone in the Oxford collection, 4-5 inches long, 

 is supposed to belong to this species : it indeed closely resembles 

 a middle metatarsal of megalosaurus ; but there is not much dif- 

 ference between that genus and crocodiles in the form of this bone. 



If the head of this teleosaurus may be taken as one-sixth of the
