Remove inter-post navigation links

At the bottom of the two posts i’ve put up so far I seem ot have a back and forward navigation link that I can’t shift. I took out the CSS that I could find in the stylesheet but thats only removed the coloured box that they were surrounded by. Where do I need to look for this bit of code to remove it?
