Super cool snail. Pusula is my best guess based on images (banded shell, gold-flecked antennae). Not sure if one can tell apart P. californiana and P. solandri from a photo like this, though some sources say the latter is more of a SoCal species. It seems like this is also called Trivia, and Light's manual lists only Trivia californiana. Not sure which name is current, but maybe someone more knowledgeable about CA inverts can chime in.

Trivia is the current name and I'm pretty certain T. californiana is the only one found in central/northern CA.

Yes! thank you! my far more knowledgeable dive buddy ID-ed it for me as Trivia at the time but my memory was a little shaky along with the rest of my body at the time....How do you guys go about looking these up? I'm very impressed

If I'm at a complete loss I usually start with some kind of pictorial guide. In this case it was The Beachcomber's Guide to Seashore Life of California. If I find something close I'll search books and the web for congeners and other alternatives since casual guides like that usually aren't comprehensive. I also use Google Images a lot for the same purpose, maybe searching for things like "striped shell monterey" or something.

If that fails I'll try to key things out in Light's manual, which is this giant taxonomic manual to intertidal inverts of central CA. It's super technical, so I usually don't get very far.

In 2014, in a study of what used to be the whole old genus Trivia, this species was moved from the genus Pusula to a new genus Pseudopusula.

The other (bigger, more southerly) species is still Pusula solandri. That species only ranges as far north as Palos Verdes, but occurs all the way south to Panama.
