As already mentioned, in the two or three vertebrae (pectorals) behind the cervical series the rib-articulation is borne partly on the centrum and partly on the arch; in the dorsal region it passes entirely on to the arch and is situated at the end of a more or less elongated transverse process ().)- In the anterior dorsal region these processes are comparatively short and stout (PI.

Further back the processes arise higher and higher up the arch, and at the same time they become more slender at the base and curve a little backwards, so that the rib-
