pairs of ribs possess heads. Tlie skull of this specimen shows that the 

 auitual was quite youuj^"; the bouudaries of the occipital eleaieuts are 

 plainly discernible. 



The skull " b " is also youug and shows the outlines of the occipital 

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

 mind me of those of Sa<jmatia-i amblodon. The hinder margins of the 

 temporal fossae are but faintly marked out in this and the ijreceding 

 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 sj'm- 

 })hysis is very short. I counted the following vertebra;: C. 7, D. 18, 

 L. and Ca. 45 = 05. The first six pairs of ribs are furnished with 

 heads and five pairs join the sternum. The scapula is 0*="' high, ll.!)*^^^'" 

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

 is 11. 7*='" long and 6.3^"' wide in front. The atlas 11.9'"' wide, 7.0'"' 

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

 teriorly and bend sli<:htly forward in the lumbar region, in this respect 

 somewhat resembling those of Lii'jenorhijnchus. Only the atlas and axis 

 are united.
