Nudibranch ID

My wife & I did a dive this afternoon at Redondo and found a nudi that is new to us. I think I identified it from Behren's book as a Ridge-tailed Dorid (diaphorodoris lirulatocauda). Can anyone confirm?
I also want to confirm the ID of this guy, who I think is a Pearly Nudibranch (Flabellina japonica)

My initial guesses** put the first one as a small/young Barnacle Eating Dorid, Onchidoris bilamellata, and the second one as a Shaggy Mouse, Aeolidia papillosa.
** meaning I'm too lazy to do much research, and these are the critters I'm familiar with

I agree with the shaggy mouse . The photos in my books do not show two rows, which is what led me astray. Behrens describes the ridge tail as having unusually long antennae and distinct white spots which matches this photo.

Agreed about the first one, Onchidoris bilamellata.

Consider another possibility for the first one :

I think Jan might have it.
Definitely not a barnacle-eating nudi ... they have more rounded papillae ...
