Bath sink drain ...

Weird. Whatever it is it appears to have leaked judging by the stains.

Without xray vision I'll hazard a guess you're looking at a bottle trap set in the floor of the vanity, a type of internal partition trap, which are not allowed by most codes (partitions can fail/erode allowing passage of gas and they don't scour, hence the handy clean out at the top for clearing snags).

Thanks. This is below an S trap in a 1974 home, if that makes any difference. S traps are rampant in these parts, even in new construction. I imagine many inspectors don't even bother.
