In Balcena the atlas is united to the other cervical vertebra?. The 

 atlas has a nearly circular body, with the lateral process on the upper 

 part of the lateral edge ; the process has a straight upper edge and 

 a slanting lower one, gradually shelving down towards the lower 

 part of the side of the body of the vertebra, where it is confluent 

 with the upper part of the base of the large, thick, lower lateral 

 process of the second cervical vertebra. 



The upper lateral process of the second vertebra is large and well 

 developed, bent forwards at the end, coherent with the ottter end of 

 the upi^er part of the lateral process of the atlas. 



The upper lateral processes of the third and succeeding vertebra? 

 are similar, but smaller, and united at the end to the upper pro- 

 cess of the preceding cervical vertebra. The lower lateral processes 

 are less developed, and unfortunately they are imperfect in the 

 specimen. 



The atlas and other cervical vertebrfe of the Lagoeetus latifrons 

 are aU united into a single mass. The body of the vertebra? is 

 nearly circular, with a very large superior conical process formed of 

 the united neural arches ; and 'on the lower part of each side, on a 

 level with, the lower edge, are two large, thick, conical processes.
