The following are parts of the same skeleton of the Layotis Cuvieri, 



Presented by J. B. Pentland, Esq. 



2017. The atlas. 



The transverse process is pierced both horizontally and obliquely, and the vertebral artery 

 also perforates the neural arch. 



2018. The axis. 



The under part of its body presents a flattened triangular discoid hypapophysis. 



2019. The fourth cervical vertebra. 



It shows the transversely oval form of the capacious neural canal. 



2020. The seventh cervical vertebra. 



It shows the simple imperforate transverse processes. 



2021. A middle dorsal vertebra. 



It shows the articular surfaces for the ribs upon the centrum and diapophysis : also, the 

 distinct anterior and posterior zygapophyses, and the common base of the equally distinct 

 anapophyses and metapophyses. 



2022. The succeeding dorsal vertebra. 



In this the anapophyses and metapophyses have as distinct an origin as the zygapophyses 

 and the diapophyses. 



2023. Two lumbar vertebrae. 



In both these all the processes above mentioned are more developed, and the metapo- 

 physes have ascended upon the anterior zygapophyses. The diapophyses are elongated by 

 coalesced antroverted pleurapophyses. The centrum is carinate beneath, and the fore part 

 of the carina is produced into a small tubercle. The anapophysis is long and slender, and is 

 applied to the outside of the metapophysis of the next vertebra. 



2024. The last lumbar vertebra. 



It is characterized by the suppression of the anapophyses. 



2025. The sacrum and anterior caudal vertebrae. 



Only two vertebrae are here anchylosed. Each is characterized by a very long compressed 

 spine : the metapophyses are retained at the sides of the interspace between the spines.
