Early dorsal vertebrae, reputed to be part of 
the foregoing series, but showing characters 
that might belong to a different species. 
They are intermediate in osteological posi¬ 
tion between the series on Shelf c , called 
mid and early dorsal. 
An associated series of vertebrae of a dif¬ 
ferent species, including cervical, early 
dorsal and mid-dorsal bones. The species 
is characterized by greater antero-posterior 
length of centrum, by stronger processes 
for ribs, and by lateral compression on the 
under side. 
Atlas and axis, 3rd cervical, early dorsal, 
and late dorsal vertebra of a small species 
distinct from the foregoing.

1 —7 Early dorsal, mid-dorsal vertebrae, and ribs. 
1—14 Late dorsal, early middle and late caudal 
vertebrae, fragment of humerus, epiotic and 
undetermined bone. 
This is a selection from an associated 
series numbering nearly 50 vertebrae. 
They are badly preserved, and, from 
some of the bones being invested with 
iron pyrites, appear to have lain on the 
Galt. They are regarded as a distinct 
species from the series a, b , c, and from 
d . 3—9 ; differing from the former in 
greater breadth, and rotundity of trans¬ 
verse outline, especially on the ventral 
part of the centrum; and from the 
latter in wanting the pinched aspect of 
the ventral surface of the centrum. 
g . 1 shows on the left side three articular 
tubercles for the rib.
