30 ’ MR. ST. GEORGE MIVART ON THE 
THE DORSAL VERTEBR. 
These vertebrae, the twentieth to the twenty-fourth inclusive, closely resemble the 
dorsal vertebre of Dromeus; but it is only the first which has a hypapophysis, and 
that is single and median. 
THE DORSO-LUMBAR VERTEBR/i. 
‘These vertebre, the twenty-fifth and twenty-sixth (the twenty-fifth, -sixth, and -seventh 
in ©. australis), so closely resemble the corresponding vertebre of Dromeus that the 
minute differences may be disregarded. ‘The last dorso-lumbar vertebra becomes 
ankylosed to the pelvis. 
THE LUMBAR VERTEBRA. 
‘The twenty-seventh vertebra (the twenty-sixth of C. bennettii and the twenty-eighth of 
C. australis) is part of the pelvic mass, and the first vertebra which has no conspicuous 
rib. It is still less concave ventrally than is its homologue in Dromeus; and its trans- 
verse process is still less directed preaxially. 
The next four vertebra, the twenty-eighth to the thirty-first inclusive, seem quite to 
resemble the corresponding ones of Dromwus, except that they are less concave 
ventrally. 
The thirty-second and thirty-third vertebre differ from those of Dromeus in that 
their transverse processes do not blend together so early. 
The thirty-fourth, -fifth, and -sixth vertebre are devoid of transverse processes, and 
have them represented only by minute rudiments. They are the LUMBO-SACRAL vertebre.
