downwards on the left side is the inferior oblique process. The cup- 

 shaped articulating surface for the head of the third cervical vertebra 

 is well seen. 



This specimen was in the collection of fossils brought from Perim 

 Island by Captain Fulljames, and was described and figured by Dr. 

 Falconer in the Quarterly Journal of the Geol. Soc, vol. i. Plate XIV.
