The I was able to obtain photocopies of all of the pages first printed works dealing with Crustacea (Belon, 1553, of these manuscripts dealing with Crustacea. Many 1555; Rondelet, 1554; Aldrovandus, 1606, etc.) mainly illustrations are present, among them several showing dealt with Mediterranean species. But it was not until species that had been insufficiently described by Risso. A. Risso in 1816 published his "Histoire Naturelle des In several instances they enabled the identification of Crustaces des environs de Nice" that the knowledge the dubious species. of the Mediterranean Crustacea obtained a firm basis. In the present paper I have listed all species of After the publication of Linnaeus's Systema Naturae and before 1816, it is true, several publications appeared in Decapod and Stomatopod Crustacea dealt with by Risso which Mediterranean Crustacea were dealt with (Briin- in his various publications and in his manuscripts.
