PROC. BIOL. SOC. WASH. 92(4), 1979, pp. 773-782 RECTIFICATIONS IN THE NOMENCLATURE OF SOME INDO-PACIFIC LITTORINIDAE Winston F. Ponder and Joseph Rosewater Abstract. — Three species previously placed in the subgenus Littoraria Griffith and Pidgeon, 1834, are reassigned to Austrolittorina Rosewater, 1970. Several other nomenclatorial inconsistencies involving species of Indo-Pacific Littorinidae are clarified. New information which has become available since the publication by Rosewater (1970) of a classification of Indo-Pacific Littorinidae, subfamily Littorininae, has resulted in changes in the subgeneric assignments of cer-tain species. Assignments to subgenera had then to be made subjectively in some cases because of the lack of anatomical material, and decisions as to placement were based mainly on shell characteristics. As animals have now become available and have been examined with special reference to the radulae and male reproductive anatomy, certain changes have been deemed necessary. The opportunity is also taken to rectify the taxonomy of two small Aus-tralian littorinids not included in Rosewater' s (1970) revision: Laevilitorina johnstoni (Cotton, 1945), and L. mariae (T. Woods, 1876). In addition several other changes are brought to light, all of which are summarized in Table 1. Littorina {Austrolittorina) acutispira E. A. Smith, 1892. PI. l,figs. 1-4; PI. 2, fig. 5 Littorina acutispira E. A. Smith, 1892:487, pi. 40, fig. 3. — Rosewater, 1970:451, pi. 349, fig. 3; pi. 351, fig. 1. Types: 14 syntypes (B.M.N.H.\ 1891.11.6.216-225). Rock pools, Green Point, Watson Bay, Port Jackson, New South Wales. Littorina infans E. A. Smith, 1892:488, pi. 40, fig. 4; Rosewater, 1970:452, pi. 351, fig. 2. Types:— 14 syntypes (B.M.N.H., 1891.11.6.226-235). Green Point, Watson Bay, Port Jackson, New South Wales. Remarks. — Rosewater (1970) tentatively placed L. acutispira in the sub-genus Littoraria Griffith and Pidgeon, 1834, and L. infans was considered a doubtful member of the Littorinidae. Large samples collected in the vi-^ British Museum (Natural History), London.
