these animals was 20 19J, and 10 J inches respectively. The 
massive transverse processes were each perforated by a large oval 
foramen, the boundary of which was ossified in the adults, and also 
on the right side of the young Alloa specimen, but on the left side it 
was completed by cartilage. In the Granton specimen the superior 
and inferior transverse processes of the 3rd cervical had joined exter- 
nally so as to complete the boundary of the vertebrarterial foramen ; 
but in the 4th, 5th, and 6 th they did not quite meet, so that the 
osseous boundary was incomplete externally. In the Dunbar speci- 
men the osseous boundary of this foramen externally was incomplete 
in the 3rd as well as in the 4th, 5th, and 6th cervicals. In the 
Alloa specimen, and apparently also in Knox’s skeleton, the 
boundaries of these foramina were completed by bars of cartilage. 
In the 7th cervical, the inferior transverse process was represented 
by a faint tuberosity on the side of the body ; but the superior was 
long, and the diameter between the tips of these processes was in the 
Granton specimen 19 J inches, and in that from Dunbar 15 J inches. 
The neural arches were complete in all the cervicals in the adult 
animals, except in the 3rd, in which a gap of If inch existed in the 
Dunbar specimen, whilst in that from Granton a chink admitting 
the blade of a scalpel separated the right lamina from the spinous 
process. 
The dorsal mrtehrcB in the Granton specimen increased in magni- 
tude from before backwards, both as regards the bodies and spinous 
processes. The transverse processes of the 1st dorsal were not 
quite so long as those of the last cervical, but were longer than those 
of the 2nd, 3rd, and 4th dorsals. A mesial keel appeared on the 
ventral surface of the body of the 4th dorsal, and was seen also in 
those which were posterior to it. The relative magnitude of the 
1st and last dorsal vertebrae was as follows in inches : —
