612 PROF, H. G. SEELEY ON THE DINOSAURIA OF 
Tue Hinp Limes. 
The Femur (Pl. XXXY. fig. 6) is very imperfectly preserved, 
having been considerably fractured by the workmen. A portion of 
the proximal end is preserved, which is about 34 inches long, and 
displays a small piece of the outermost part of the proximal articu- 
lation (a), showing it to have been comparatively smooth and 
slightly convex from front to back, in which direction the measure- 
ment was rather more than 1 inch. The bone was flattened behind, 
but was not flattened on the external aspect at the proximal end. 
Here it is convex from within outward, and also rounds into the 
posterior surface. In front there is a strong proximal trochanter 
(fig. 6, b), somewhat of the type seen in Jguanodon, but more 
compressed ; it is closely adherent to the shaft without being anchy- 
losed to it. The cleft on the posterior side is more marked than on 
the anterior side, and extends for 13 inch below the proximal arti- 
cular surface. ‘This trochanter is broken away in its upper part, 
but its base is 74) inch wide and nearly ;%, inch thick. The inner 
half of the proximal end of the bone is broken away. 
The distal end is represented by a small portion of the shaft, also 
of a left femur, and therefore presumably the same bone. It is 
from just above the distal condyles, and shows on the posterior sur- 
face the usual groove between the condyles, which is placed, as 
usual, nearer to the inner than to the outer side of the bone. The 
fragment, which is only 14 inch long, is 2 inches wide at the distal 
end, and the greatest antero-posterior measurement is 1, inch, 
while in the condylar groove (fig. 7, a) the measurement is $4 inch. 
The front is flattened, with a slight tendency to a median longitudinal 
depression. ‘The inner side is slightly flatter than the outer side; 
but both are well rounded, and round into the two halves of the 
posterior surface. There is no indication of any expansion of the 
bone at the distal end, and it is improbable that the strong external 
muscular process seen in some genera was here developed. 
The bone had a large medullary cavity; it is dense at its circum- 
ference, and finely cellular internally. I estimate the length of this 
femur to have been about 12 inches. Its distinctive features are 
the compression and position of the proximal trochanter. Its im- 
perfect preservation renders comparison with other types at present 
difficult. 
The Tibia.—The left tibia is represented by two fragments of the 
shaft, which give no indications of the forms of either the proximal 
or distal articular ends. The distal end decayed before fossilization, 
but the proximal end and middle of the shaft appear to have perished 
under blows from the diggers’ picks. Proximally the larger frag- 
ment is triangular, being flattened behind and obliquely compressed 
from side to side so as to form a strong cnemial crest, which is di- 
rected outward in front of the proximal end of the fibula. The 
oblique inner and anterior surface of the bone is flattened. The 
external or fibular side (Pl. XXXYV. fig. 8,a) is gently channelled 
from front to back. The width of the fragment, as preserved, from
