704 THE AMERICAN NATURALIST [Vol. XL VIII 



bone is pierced by two large foramina; each of the other two 

 bones shows in this view a foramen which branches and opens 

 both on the antero-median and the postero-lateral surfaces. The 



ventral view. Fig. 2. shows a very irregular group of bones, the 

 smallest of which is for articulation with the following vertebra. 



The second vertebra (ax), supposedly the axis, exhibits no 

 indication of an odontoid process and articulates in a very crude 

 way with the preceding bone. Its dorsal spine is rather elon- 

 gated in an antero-posterior direction, but otherwise it bears no 

 closer resemblance to an axis than to any other cervical vertebra. 



The third vertebra exhibits no peculiarities that warrant de- 

 scription.
