pairs of ribs possess beads. The skull of tliis specimen shows that the 

 animal was quite 3'ouug; the bouudaries of the occipital elemeuts are 

 plaiuly discernible. 



The skull "^" is also young and shows the outlines of the occipital 

 element. The intermaxillai are very thick and high proximally and re- 

 mind me of those of Sagmatiai anibludon. The hinder margins of the 

 temporal fossaj are but faintly marked out in this and the preceding 

 skull. 



The skeleton No. 1670a, at Oxford, is also young. The palate is very 

 flat, the rami of the mandible are strongly bent outward, and the sym- 

 physis is very short. I counted the following vertebra': C. 7, D. 13, 

 L. and Ca. 45 = 05. The first six i)airs of ribs are furnished witli 

 heads and five pairs join the sternum. The scapula is 9*='" high, 11.9^'" 

 long. The humerus and radius together measures 9.7"". The sternum 

 is 11.7^'" long and ii.o"" wide in front. The atlas 11.9"" wide, 7.0'"' 

 deep. The carpels are five. Tiie neural spines are narrow antero-pos- 

 teriorly and bend slightly forward in the lumbar region, in this respect 

 somewhat resembling those of LaQenorhijnehas. Only the atlas and axis 

 are iinited.
