What is this thing?!?

This appeared on my glass today - there's a virtually identical one on another location on the glass. Are they eggs from snails?
Anyone?
Thanks!

spiropid(sp) worm nm i dont know it looks like the pic of a sea squirt but.....not

I don't think so... I have plenty of spirobid worms and these do not look the same. This thing is about 1-2 inches long and the white lines are actually individual white specks. I'm thinking that a snail may have slowly laid eggs or something...
