The cephalic articular surfaces face clorsally and medially ; the 

 caudal articular surfaces lace ventrally and laterally. The neural 

 canal is wide and high, hut not long (Figs. 27 and 28). The spinous

process is about as long as the neural canal. It is flattened from 

 side to side, and pointed at the end, which is sometimes turned toward 

 the tail. Its general direction is dorsal and cephalic. The striking- 

 peculiarity of this vertebra lies in the form of the transverse processes. 

 Each transverse process has a short basal portion pierced by the 

 arterial canal (Fig. 28). The dorsal wall of the canal is thicker than
