Well all of these are untranslated:
Shirogane Otome: A yuri harem game, haven't finished it due too distractions but it has been quite humorous. A warning though one of the heroines is a Trap, that there is 3 or so scenes with. Altough she becomes a female in the end so i still count it as a true yuri.
Syojokyu: A high drama, lots of sex, yuri vn set in a catholic school with art that makes the charactersgives the characters a somewhat loli look.
Class Zenin Maji de Yuri?! ~Watashi-tachi no Rezu Oppai wa Anata no Mono Joshi Zenin Shiofuki Keikaku~: A crappy yuri nukige with alot of boobs, panties and one dimensional characters.
WET BLUE ~Poolside no Tenshi-tachi~: A poolside centered yuri lolicon game.
Also some i haven't played so can't say that much about them:
Anaheim Girl's Love Story: Mecha yuri storiy that has been translated but not patched.
Fermion ~Mirai kara no Houmonsha~: old school (1995) sci fi yuri, think it contains male rape bad ends though.
Okujou no Yurirei-san: High school yuri with multiple pairs, have heard it should be quite good but haven't gotten around too try it.
Yuri no Hana Natsu Monogatari ~Amanogawa no Kirameki wo Kimi to~: Think its a highschool setting with quite a bit of sex, and there seems to be a whole "Yuri no Hana" series altough i can't say they seem that interesting.
As an endnote i would recommend aoishiro from the previous poster again, it's one of the best games i've read, even though it only really contains one heroine where you know they end up together as more than friends..
Also incase you don't know a good place to search for vns is here http://vndb.org/ , also if you want to search multiple tags (like say excluding male protagonist or rape) you have ot click visual novels then tags.
