422 J. W. HULKE ON A NEW WEALDEN DINOSAUR. 
stout and trihedral. Extending directly outwards, they reach to 
nearly 1-3 inch beyond the root of the neural spine. Their upper 
surface is a flat triangular table with a rounded apex at the free end. 
The anterior border, stouter and shorter than the posterior, is im- 
pressed with a rib-pit close to the preezygapophysis ; and the free end 
of the process is distinctly articular. The posterior border is produced 
backwards along the summit of the neural arch to the postzygapo- 
physis, which gives to the transverse process the platform-like figure 
which has been considered characteristic of Dinosauria. The under 
surface of the process is upborne by a buttress which, beginning 
near the posterior inferior angle of the neurapophysis, is directed 
upwards and forwards, and extended nearly to the free end of the 
process. No. 28, a neural arch, somewhat squeezed by post mortem 
pressure, which has become detached from the centrum along the 
suture, has a similar transverse process to No. 24; but this slants 
backwards more than directly outwards, and a longer space intervenes 
between the capitular costal pit near the prezygapophysis and the 
tubercular articulation at the free end of the process. The anterior 
border of the process between the two rib-joints has also a linear in- 
dentation, against which the rib, when articulated, rested, as in extant 
crocodiles. The prezygapophyses have a stronger inward inclination 
in this vertebra than in No. 24. I regard this vertebra (No. 28) as 
dorsal, and as corresponding nearly to the 15th or 16th presacral ver- 
tebra in Crocodilus niloticus. Nos.25 and 26 are in undoubted natural 
sequence, the left postzygapophysis of No. 25 being cemented by 
fossilization to the corresponding prezygapophysis of No. 26. The 
neural arch is loftier than in No. 24 ; and the transverse process (lost) 
appears by its root to have been moreslender. The postzygapophyses 
very considerably overhang the posterior plane of the centrum. 
The neural spine, which was broken off but lying in juxtaposition 
with its centrum, is an oblong blade about 4 inches high and having 
near its free end an antero-posterior extent of 1°2imch. Its front 
border is thin ; its posterior is cleft towards the base by a deep groove, 
which, in the articulated vertebral column, received the anterior 
border of the spinous process of the vertebra behind it. 
The postsacral vertebra (figs. 2, 3) has lost its neural arch, which 
has become separated at the suture. Both articular surfaces are de- 
cidedly concave. Their circumferential contour is subcordate: the 
upper portion, straight, is the widest part of the centrum; it meets 
the lateral portions somewhat angularly. The lateral surface of the 
centrum is concave longitudinally, and nearly plane vertically from 
the neural suture to the lower border, which it meets in a slightly 
angulated ridge that begins behind at the chevron facet, and is sepa- 
rated from the ridge of the other side by a shallow median depression. 
On the posterior border of this, the inferior surface of the centrum, 
the chevron facet is very conspicuous, and it seems almost subdivided. 
The transverse process (lost) was attached at the line of junction of 
the neurapophysis and centrum. I take this vertebra to have been 
not far behind the sacrum, at the root of the tail. 
The bone (No. 22) which I regard as an ilium (fig. 1) consists
