Gymnuridae

* Gymnura altavela (Linnaeus, 1758)—Spiny butterfly ray

Gymnura hirundo (Lowe, 1843) —Madeira butterfly ray

Though the species was originally described from Madeira, it is not mentioned by McEachran & Capapé in Whitehead et al. (1984), who treated it as a doubtful species. The species was considered as valid by McEachran & Séret in Quéro et al. (1990: 65) and as questionably valid by Compagno (1999: 497). There are no specimens in the collection of the MMF.
