The identification of Aglaja tricolorata has a confused history, and although most authors now consider the animal illustrated here to be A. tricolorata, I have a slight doubt because some reports describe an orange and a blue line at the edge of the parapodia, which has certainly not been noted in any specimen which looks like the accompanying photograph. Until Martinez et al's anatomical study (1993) of aglajids from the Iberian Peninsula, our knowledge of this species was based on Vayssiere (1880 - as Doridium membranaceum) and copied by Pilsbry (1896) and Pruvot-Fol (1954).
