The whole bone thus gets a ring-like form, and the salient processes of other vertebrae are but little de- veloped, with the exception of the transverse processes, which are wide and wing - like. In many Marsupials, such as the AV(unbat and Kangaroo, the arch of the atlas is open below, there being no centre of ossification. In others, such as Thylaciims, there is a distinct nodule of bone in this situation not con- crescent with the rest of the arch. The second vertebra, which is known as the axis or epi- stropheus, is a compound structure, the anterior " odontoid process, '' which fits into the ring of the atlas, being in reality the detached centrum of that vertebra.^ It is a curious fact about that jirocess that it has independently become spoon-sliaped in two divisions of Ungulates; that it has become so seems to be shown by the fact that in the earlier types of both it has the simple peg-like form, which is the prevailing form. The cervical ^ Its independence from the epistropheus is emphasised in Monotremes and some Marsupials by its late fusion with that vertebra..
