In young kittens four portions may be distinguished in this bone. These are, a basal portion (the basioccipital bone), two lateral portions (the exoccipital bones), and a dorsal por- tion (the supraoccipital bone). These four bones remain separate through life in many lower vertebrates. In the adult cat they are completely united into a single bone, but it is convenient to describe this bone as made up of four parts: a basal portion {a) (pars basilare), corresponding to the basi- occipital, two lateral portions {b) (partes laterales), corre- sponding to the exoccipitals, and a squamous portion {c) squama occipitalis) corresponding to the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Reighard, Jacob Ellsworth, 1861-1942; Jennings, H.
