In connection with his original description of the type-skeleton, Cope recorded 
a number of measurements, some of which are taken from the same points as those 
above, and others from different points. Thus, the length of the forelimb is given 
as 9.05 feet, which is, of course, erroneous, and due to the incorrect mounting of the 
skeleton. The breadth of the cranium between the orbital processes of the frontals 
is given as 6.41 feet, and the breadth between the coronoids of the mandible, 5.75 
feet. The height of the scapula is recorded as 29.6 inches, and its breadth, as 44.4 
inches, which, it will be seen, are close approximations to my own measurements as 
given above. 
In the type-skeleton of JZ. osphyia all the epiphyses are unattached. Those 
of the vertebre are held together in pairs by the dried intervertebral cartilage. A 
few are wanting. The vertebra present are as follows: C. 7, D. 14, L. 10, Ca. 17 
= 48. Fourteen ribs are present on the right side and thirteen on the left side. 
Cope mentioned fourteen pairs of ribs, so that it is possible that one rib has been 
lost since he examined the skeleton. 
Skull—The nasal bones are wanting. The anterior border of the orbital 
process of the frontal is nearly straight. The breadth of the skull between the 
distal extremities of the orbital processes is six feet five and one-half inches. 
The occiput is swollen laterally, with a quite deep central depression and a small 
median ridge. The coronoid processes of the mandible are low and blunt, but the 
tips have, as already stated, apparently been cut off. 
Vertebre.—The antero-posterior length of the centra of the vertebre present, 
without the epiphyses, is as follows:
