depressed, rapidl}' decreasing in size. The transverse pro- 

 cesses are slender. Tlie very low neural spines anchylose 

 into a long ridge. The number cannot be ascertained, owing 

 to the fragmentary state of the sacrum. The caudals in- 

 dicate a tail of not very great length ; as the neural canal is 

 small and persists in only a few of the anterior vertebras.

The ribs, of which great quantities of fragments remain, 

 were slender and not of very great width. 



The femw, which is figured in Plate I., has a small head, 

 supported by a short neck. The shaft, very broad below the 

 head, supports the third trochanter one third of the way 

 down ; below which it takes a cylindrical form, and expands 

 slightly above the trochlea. The two condyles, separated by 

 a wide and deep popliteal groove, are nearly sub-equal in 

 size — the internal somewhat the larger, while the trochlea is 

 long, narrow, and symmetrical. The great trochanter rises 

 slightly above the head, and overhangs a long and quite 

 deep digital fossa. The second trochanter is small. The 

 popliteal space is slightly concave. 



Tibia. — The proximal end of the tibia is very large, wnth 

 massive rugosities for muscular attachment. The two prox- 

 imal faces are sub-equal, slightly convex, and separated by a 

 prominent spine, which is grooved at the top. The shaft is 

 long, straight, and compressed antero-posteriorly ; the ante- 

 rior ridge on upper third is ver}^ high, and expands into the
