OK, now I'm confused. It looks to me like breits have a complete ocular ring, including preocs. Are you saying there is a lack of preocs in breitensteini? Zach says that brongersmai have no subocs but from the picture they look like they do have preocs. I'm trying to get this straight. I was memorizing "breits and curtis have subocs, brongers do not." Now I' rattled!
