This peculiar condition of the cervical metapophysis is well seen 
in large specimens of the genus Canis*, in which (figs. 7 & 9, m) 
the third dorsal vertebra, like all those posterior to it, bears its own 
metapophysis only, and supports the whole of it. The second dorsal

vertebra bears but a portion of its metapophysis, which is continued 
on to the first dorsal vertebra. This first dorsal supports the other 
part of the metapophysis of the second dorsal, but scarcely any of its 
own, which, on the other hand, is almost entirely borne by the seventh 
cervical vertebra upon its posterior zygapophysis. The sixth cervical 
vertebra similarly supports the metapophysis of the seventh cervical ; 
but in addition it bears, beneath and outside its anterior zygapo- 
physis, a marked portion of its own true and proper metapophysis. 
The same is the case in the fifth cervical vertebra; the fourth, how- 
ever, bears scarcely any of the metapophysis of the fifth cervical, 
but, on the other hand, has its own metapophysis well developed, and 
situated in its normal position, beneath the anterior zygapophysis. 
In the Malay Tapirt the cervical metapophyses are strongly 
marked, and are somewhat divided, the greater part of each being in 
the normal position beneath the anterior zygapophysis, but part also 
being above the posterior zygapophysis next in front, in the last five 
cervical vertebree. 
In the Indian Rhinocerost the cervical metapophyses are almost 
entirely confined to the anterior zygapophyses.
