What are these odd lines?

What are these strange marks appearing on my prints? I can't reason out what they are. Looks almost like some in camera flaring, but they are definitly not represented on the negatives. And any odd light reflections hitting the paper would make it darker, not lighter. The set of prints I made before this one din't have these starnge lines, and the last two negatives I tried printed have been showing them. Any Ideas?

On second look, the condesors seems to not be in as good as a shape as I originally thought. Can see the black lines easily when I remove the negative. Thought I can't figure out why they didn't show up on the last prints I was making.

I was going to tell you they are sprites - small, alien negative-energy beings, flying around in your dark room, but it sounds like you've identified the source.
