Found in brackish water on the coast of County Wexford. Eylais neglecta, Sig Thor. 1899. Arch. Naturv. Christian, vol. xxi. p. 12, pi. xvii. figs. 156-158. A form resembling this species occurs in Ireland. The group to which it belongs is an extremely difficult one to differentiate with any degree of certainty. I have taken specimens approaching very closely to E. similis, Thon, E. tenera, Thon, E. rimosa, Piersig, &c, in the structure of the eye-plates. Owing, however, to the great variation which occurs, I should prefer to treat these Irish specimens as varieties or aberrations of the same species. Eylais undulosa, Koenike. 1897. Ver. Bremen, Bd. xiv. pp. 283, 295, fig. 2. This is certainly an Irish species ; specimens taken in the Koyal Canal, near Dublin, agree very well with the types.
