Ribs. — Imbedded in the same blocks of stone with the vertebrse 

 and jaws are fragments of several ribs. The longest of these, 12 

 inches long, lies across the outer surface of the lower jaw. Por 10 

 inches it is cylindrical ; and it has an average diameter of '8 inch. 

 Its distal end is flattened ; the flatness may have been slightly in- 

 creased by squeezing, as the texture of the bone shows here signs of 

 crushing. Its vertebral end is forked, and some of the other frag- 

 ments are also distinctly bifurcated ; but in none are the actual 

 articular surfaces preserved. 



Limb-hones. — The only limb-bone which I can identify is a long 

 bone, the distal half of which is seen lying across the lower jaw. 

 Its proximal half has been exposed in the reverse side of another 

 block, so that, very unfortunately, the entire bone cannot be viewed 

 at once. The broken ends, however, fit accurately, and there can- 

 not be the slightest doubt of the original continuity of the two 

 pieces. This bone agrees more closely with the femur of the liv- 

 ing crocodile than with the humerus of this latter ; and on this 

 ground I believe it to he the femur, the left one. In its present state 

 it is 14 inches long. The proximal end is expanded transversely, 

 and it measures 3 inches across. Its under surface bears a subhemi-
