Among the synonyms is F. nimbosa (afterwards rosea) of Philippi, but not Patella nimbosa of Linne. 1. EMARGINULA FISSURA, Linn§. Patella fissura, L. S. N. p. 1261. E. fissura, B.

His description of the colour (" rubra aut albo rubroque variegata") is not applicable; and the habitat ("les mers de l'Europe?") is given with a doubt. He does not even notice any transverse striae. The aberrant form or variety (E. pileolus, Michaud=£l. capuli-formis, Philippi, = E. curvirostris, Deshayes, = E. costa, Tiberi) is connected with the typical form by intermediate and insensible gradations. 3.
