neural arch (126), and neural spine (43). (Plate XL) This 

 is seen also in text fig. 2. 



The 5th vertebra (88) of the spinal column is here seen pos- 

 teriorly. It shows the neural spine (43), neural arch (126), 

 centrum, and transverse processes (46). The last are here 

 horizontal, and receive the articulation of a pair of double ribs. 

 (Refer to Plate XI.) The neural spine of this vertebra may be 

 seen in Plate I. 



The 6th vertebra (89), 6th of the spinal column, seen from the 

 left side shows the neural spine (43), while the transverse 

 processes are over the body of the vertebra. Prezygapophyses 

 (127) and small postzygapophyses (128) are seen. This is 

 shown in Plate XI from the left side, and the neural spine is 

 indicated in Plate I.

The 7th vertebra (90) (42 in Plate I) is seen from the 

 anterior side, showing the neural spine (43), the transverse 

 processes (47), the neural arch, and the centrum (97). This 

 is indicated in Plate XI and, also, in Plate I. 



The 20th vertebra (91), from the posterior side in Plate XI, 

 shows the transverse process (49), the neural spine (43), the 

 neural arch, and the centrum (98). Transverse processes are 

 here passing toward the vertical. Plate I also shows this ver- 

 tebra from the left side. 



The 21st vertebra (92) is viewed from the left side. It 

 shows the prezygapophysis (127), the postzygapophysis (128), 

 neural spine (125 and 43), and the transverse process (49). 

 The transverse processes approach more nearly the vertical. 

 Plates I and XI illustrate this vertebra. 



The 22d vertebra (93) shows the neural spine (43), centrum
