Sorry about the cutting off of the end of the jaw there. it is in the next view which is a three quarters view. Note the bones of the ear canal. pretty low placement considering how high the ears seem to sit on a live monkey. my thumb is resting on the rest of the structure. which will be shown in the bottom view. also the brain case seems to be rather large but the front third of that is indeed where the eyes sit back in the skull. so while the frontal lobe does extend bewteen the eyes the bulk of the brain sits in the back two thirds of the brain case.
