Nymphalis vaualbum or N. l-album, the Compton tortoiseshell, or false comma, is a species of butterfly in the family Nymphalidae.

An assertion that the name Nymphalis l-album is in fact the correct name over the widely used Nymphalis vaualbum proved to have backing when it was discovered the description covering vaualbum did not include a description or type specimen. Thus vaualbum can be considered nomen nudum, giving Nymphalis l-album priority.
