Marocco (Chemnitz), Algiers (Weinkauff, Jolg), Cadiz, Algesiras and Malaga (Hidalgo). I quite agree with Herr Weinkauff that this is Gmelin's species, which was founded on the description and figures of Chemnitz, Conch. Cab. v. p. 271, t. 188. f. 1917, 1918. It is Natica textilis of Reeve, and N. intricatoides of Hildago ex typo.

Pliocene : Coralline Crag (as N. multipunctata of S. Wood), Belgian Crag, South of France, Italy, and Algeria. Post-tertiary: Morea, Rhodes, Corinth, and Cyprus. Weinkauff has noted 14 synonyms. Martyn's specific name hebraa is four years older than that of Gmelin ; but, as Von Martens and Weinkauff have pointed out, Martyn's nomenclature is not in accordance with the Linnean system. Lamarck's name millepunctata has been used by many conchologists, although it must be borne in mind that the only habitats which he gave (the |
