what are these?

How would these be described?

I would describe the first one as a subset of the 1029/1024 planar
temperament, and the second as a subset of the 7-limit 81/80 planar
temperament. Since you've presented them as subsets of 31-equal, of
course other commas are tempered out, but they're not important for
the harmony.
