Bulletin of Zoological Nomenclature 54(1) March 1997 II Case 2940 Riisea and riisei Duchassaing & Michelotti, 1860 (Cnidaria, Anthozoa): proposed conservation as the correct original spellings of generic and specific names based on the surname Riise Frederick M. Bayer Department of Invertebrate Zoology, National Museum of Natural History, Washington, D.C. 20560, U.S.A. Manfred Grasshoff Forschungsinstitut und Museum Senckenberg, Senckenberganlage 25, 60325 Frankfurt am Main. Germany Abstract. The purpose of this apphcation is to conserve the name Riisea for a genus of gorgonian corals, and the specific names of Carijoa riisei (originally in Clavularia) and Thalamoplxyllia riisei (originally in Desmopliyllum). These names have been universally accepted for more than a century and are attributed to Duchassaing & Michelotti, 1860. However, the names were originally published as Rusea and rusei; they were based on the supposed personal surname Ruse or Riise, but in 1864 Duchassaing & Michelotti corrected the names to correspond with the actual surname Riise. Keywords. Nomenclature; taxonomy; Anthozoa; corals; Riisea: Carijoa riisei; Tltalamopliyllia riisei. 1. In their important memoir on West Indian corals Duchassaing & Michelotti (1860) established (p. 294 [p. 18 in the separates, also issued in I860]) the genus Rusea for the single new species of gorgonian R. paniculata. They stated that the specimen was 'donnee par Mr. Riise savant Pharmacien a St. Thomas". 2. In the same memoir Duchassaing & Michelotti established a new species of 'Alcyoniens Sclerodermiques" called Clavularia Rusei (p. 310 [p. 34]) and a species of scleractinian coral Desmophylhim Rusei (p. 337 [p. 61]); the latter was 'trouvee a St. Thomas par Mr. Ruse, Pharmacien de cette ville'. A species of 'Zoanthinae' called Gemmaria Rusei was described on p. 331 [p. 55] with the comment 'Nous la dedions a Mr Riise, Chimiste-Pharmacien des plus distingues, qui demeure a St. -Thomas et vient de la trouver dans cette lie'. 3. In a supplementary memoir Duchassaing & Michelotti (1864) recognized that there had been a mistake about the surname of the 'pharmacien': Clavularia Rusei was emended (p. 117 [p. 23 in the separates]) to C. Riisei with the comment 'On doit ecrire Riisei, non Rusei'. Similarly, but without comment, Rusea was emended (p. 108 [p. 14]) to Riisea; Desmophyllum Rusei became D. Riisei (p. 158 [p. 66]) and Gemmaria Rusei became G. Riisei (p. 1 35 [p. 43]). The surname Riise had been misread as Riise or Ruse. 4. Since there was no internal evidence of error in the original (1860) publication, under Article 33b of the Code the spellings Riisea and nwe/ are unjustified
