are two rather large lobes forming the 
articulating processes which overlap the succeeding bone, The 
transverse processes are well preserved throughout nearly the

of the articulating processes. 
The ribs, well developed throughout, are remarkably well pre- 
served; each has a short head, and behind this, a well marke 
tubercle, showing two points of articulation, and consequently
