much damaged) : 16*5

2. Dorsal vertebra. (Pl. I, Figs. 12, 14 & Pl. II, Figs. 5, 7, 
8, 10). The two remains of fossil dorsal vertebrae are probably dorsal and 
not dorsolumbal vertebrae 1 which supposition may be established by 
the large facies costalis on the part forming the centre (on the left side). 
The two remnants of dorsal vertebrae are most likely parts of the 
same vertebra, as may be surmised from the fractured surfaces and the 
faint structural lines apparent on the bones. One of the fragments re¬ 
presents the whole centre together with the anterior region of the 
upper arch, on the left side of which we find the proc. obi. ant. tolerably 
well preserved, slightly damaged only on peripherical parts ; the other frag¬ 
ment shows the posterior part of the upper arch, with, on the right 
side, proc. obi. posterior also in perfectly good condition. I therefore 
with the aid of paraffin adjusted at their corresponding extremities 
these two fragments to eachother, the vertebra thus reconstructed being 
described as follows : 
The shape of the vertebra is of a most striking Varanus type: the 
front part of the upper arch compared with the back one, formed by the 
proportionally small proc. obi. post., is very large and broad. The centre 
is wedge-shaped, with no median ridge, or only presenting a scarcely 
visible elevation on each side of the median line ; at the extremity 
of the front of these elevations we find the large, considerably deep, 
ellipsoid shaped articulating cavity, on both sides of which, in vertical 
direction, the facies costales — a clearly marked proc. trans v. not being 
present in this region of vertebral column — rise towards the upper arch, 
revealed under the form of large subellipsoid-shaped surfaces ; under the 
base of these latter, consequently on the centre, on both sides of the arti¬ 
culating cavity, two tolerably accentuated hollows are present, which 
I determine as foveae paraglenoideales. These hollows practically 
forming the base of the region represented by the facies costales and 
proc. obi. ant. have been closely examined by me on the dismembered 
spine of F. griseus Daud. 2 In this species the particularities mentioned 
are already visible on the seventh vertebra, — thus first noticeable on 
the last cervical vertebra — and whilst most marked on the ninth, tenth
