Latin help needed

[ffutures]

In Weinbaum's story the main city on Titan is called "Nivea." I've tried to look that up on line, and in other contexts (e.g. as part of a scientific name) it appears to mean "snow white" or "snowy white" according to the site I look at.

It's not particularly important, but if anyone happens to know which is correct, or if there is a better translation, I'd be grateful.
