I've never seen some of these craters before. Yes, Gauss at far left has been imaged occasionally, but Joliot, a 164 km diameter, mare-floored with a rubbled central area that looks like it was trying to form a ring. Seneca is marked with a question mark, not because I am uncertain of the identification, but I am quite doubtful that that name is warranted.
