Alicyn--I know it is rather strange anatomy. I remembered reading it in several papers, but the one I cited it in my presentation for reproduction class was: Spotorno,

There's a link to the article on the article section in this forum actually (I could have saved some time if I looked there first!!)
I may be wrong, and these papers may be wrong (I deleted all my bookmarks to the other papers after I turned in my presentation since I had so many and only needed one to cite a fact from) but my teacher has yet to correct me if they are. Don't know if he would have in front of people anyways.
