three metacarpals and one phalanx. In structure they are 
not different from those of the right hand. 
The ilium of the left side is preserved, apparently entire. It 
is elongate and cylindrical. Its upper end lies adjoining the 
twenty-eighth vertebra. 
The head of the femur lies close to the lower end of the 
ilium, so that that element must have been suspended in the 
flesh much as in the modern salamanders. It could not have 
been of much use in support. The form of the femur is not 
unlike that described for the humerus, save that its lower 
end is smaller than the upper, while in the humerus both 
extremities are alike. A portion of the right femur is pre- 
served extending in an opposite direction to the left. No por- 
tions of the leg or foot are preserved.
