below. The centrum of the most posterior vertebra preserved is as broad 
as long and the anterior and posterior faces are roughly quadrate, with 
the breadth greater than the height. The intervening vertebrae grade 
from the one type to the other. Laterally and inferiorly they are concave 
fore and aft. 
The anterior caudals bear moderately stout transverse processes, 
but these diminish rapidly as they proceed backward. They spring 
from the supero-lateral borders of the centrum and the base of the neural 
arch. 
The scapula is longer, straighter, and more slender than that element 
in T. annectens or T. edmontoni , the greatest breadth being 160 mm. and 
the greatest length 850 mm. 
The coracoid resembles that element in T. annectens , but is propor- 
tionately smaller. Part of it is broken away, so it is not possible to give 
details of the coracoid foramen, but it seems to have been surrounded 
by bone rather than an open notch. 
The ischium is long and slender and closely resembles that element 
in T. annectens. Though the distal extremity is not preserved there is no 
doubt that it was bluntly pointed as in T. annectens and other members, 
of the Hadrosaurinae. Between the face which articulates with the pubis 
and the rugose area, on the inferior surface, for articulation with the 
postpubis, there is a well-defined notch. 
The femur is long and massive and considerably curved. The great 
trochanter is large and rises above the head of the bone. The lesser 
trochanter, on the antero-external face, is separated from the great 
trochanter by a narrow channel as in T. annectens , but is smaller than in 
that species and is located at a lower level. The fourth trochanter is below 
the midlength of the bone as in the above-mentioned species. The distal 
condyles are large antero-posteriorly and the articulating surface runs well 
up the posterior face. The condyles do not unite anteriorly to enclose 
a foramen, as in some forms, the only union between the two being a 
comparatively low and narrow ridge at their midlength. Length of femur 
1,000 mm. 
The tibia is much shorter and of lighter construction than the femur. 
It closely resembles that bone in T. annectens. Length of tibia 790 mm. 
The right astragalus and calcanium are present, but show no differences, 
when compared with other members of the genus. 
Only fragments of the ribs are present and these do not appear ta 
differ from T. annectens.
