TEliTIAllY VERTEBEATA OF THE FAYEM. 
Tlio length ol’ tlie upper teeth from pm. 2 to m. 3 is tlierefore about 34'5 cm. against 
about 2(3 cm. in A. zilleli. The lengtli of tlie lower molar series is 23*5 cm., that of 
the lower prcmolars 14 cm. The total length of the mandible is 73 cm., its height at 
coronoid 43‘5 cm.; width of the condyle 12’1 cm.; width of ascending ramus 22‘5 cm.; 
depth of ramus behind m. 3, 1 1'2 cm.; length of symphysis 21’5 cm. 
The almost complete cervical vertebra has a centrum which is very short in 
proportion to its other dimensions. Its measurements are : width of centrum 
18'.') cm. ; height of ditto 1,5’2 cm.; length of ditto 4'8 cm. The posterior thoracic 
and lumbar vertebra? have both lost their anterior epiphyses, indicating that the 
animal was comparatively young, an Inference that is confirmed by the slight degree 
of wear of the third molar in both jaws. The dimensions (in centimetres) of the 
thoracic vertebra are: width of centrum lt3’2 ; height of centrum 10‘5 ; length of 
centrum without anterior epiphyses 8‘2 ; height to ti]) of neural spine 24+ ; width at 
transverse processes 37. The same measurements in the case of the lumbar vertebra 
are 15'6, 1()'8, '.)'4, 30, 31‘8. The dimensions of the enormously massive humerus 
are : width of shaft at narrowest 18 ; greatest width of distal expansion 34‘5 ; width 
of distal articulation 23. In form this humerus (text-fig. 38) differs very little from 
that of the smaller species, except that the condyles are somewhat more prominent. 
The length of the rdna is GO cm. Its inner face is imperfect.

M. 8462. Back of skull and axis vertebra found in association. The dimensions (in centimetres) 
of the skull are : width above auditory opening 41 ; width of roof lietween temporal 
fossae 18'5; width between outer angles of occij)ital condyles 24 +; width of Ibramen 
macrnum 9‘5 ; height of ditto G'5. 
A maxilla and mandible (M. 84G2 n, b) found near this skull seem to be too small 
to belong to the same species ; thus in the maxilla the length of the molar series is 
only 17 cm., about the same as in A. zitteli. 
The dimensions (in centimetres) of the axis are : length along ventral surface to 
tip of odontoid 17’8 ; width of proximal end 20'3 ; width of posterior face 16.

M. 8467. Left femur. The dimensions (in centimetres) of this specimen are : length 80 ; greatest 
width of upper end 28 ; diameter of the head 13'5 ; width of middle of shaft IG'3 ; 
greatest width of distal end 20‘3 ; width of distal articulation 1,5'7.

As above remarked, it is jtrobable that bones of this species may be included amongst those 
referred to si. zitteli : e. y. the large pelvis ((1 8413) described and figured above may belong
