The purpose of this application is to conserve the accustomed understanding and usage of the names for two European pulmonate gastropods, Helix lucorum Linnaeus, 1758 and Otala punctata (Miiller, 1774) (family helicidae). The two existing syntypes of H. lucorum are specimens of O. punctata and it is proposed that these be set aside and a neotype designated in accord with accepted usage. The species Helix lucorum as currently understood is found from Italy eastwards through to the former USSR and has been introduced in France; O. punctata is present in the south of France, Spain and the north of Morocco. Both the names H. lucorum and O. punctata refer to two of the most commercialised terrestrial snails of the food industry.

The purpose of this application is to conserve the specific name of Ceratichthys micropogon Cope, 1865 (now Nocomis micropogon) for the common and widespread river chub (family cyprinidae) of eastern North America. Cope's (1865) description has been shown to have been based on a hybrid between the river chub and the common shiner, Luxilus cornutus (Mitchill, 1817). The name N. micropogon has been used consistently for the river chub since 1926 but, under Article 23.8 of the Code, it is not a valid name for the parent species of the hybrid. It is proposed that the current usage of N. micropogon for the river chub be conserved by the designation of a neotype.

The purpose of this application is to conserve the subspecific name of Holacanthus ciliaris bermudensis Goode, 1876 (currently cited as Holacanthus bermudensis) for the blue angelfish (family pomacanthidae), a common, relatively widespread and visually prominent marine reef-dwelling species occurring in the tropical Western Atlantic. Goode's (1876) original description was based partly or entirely on hybrids (a total of 12 syntypes) between the blue angelfish and the closely related queen angelfish, Holacanthus ciliaris (Linnaeus, 1758) and, under Article 23.8 of the Code, H. bermudensis is not a valid name for the parent species. It is proposed that a neotype for H. bermudensis be designated in accord with the current usage of the name

The purpose of this application is to designate a neotype for Parasuchus hislopi Lydekker, 1885, a well-known crocodile-like archosaurian reptile (phytosaur or parasuchid) from the Late Triassic Maleri Formation of India. The lectotype is fragmentary (a premaxillary rostrum), and because of this some authors have recently suggested that the name of the nominal genus Parasuchus Lydekker, 1885 (of which P. hislopi is the type species) should be replaced by Paleorhinus Williston, 1904. To maintain stability of usage and in accord with Article 75.5 of the Code it is proposed that the lectotype be set aside and a complete articulated skeleton be designated as the neotype

The purpose of this application is to conserve the name Clytia noliformis (McCrady, 1859) for a well-known marine hydroid (family campanulariidae). McCrady's (1859) type material of C. noliformis is lost but the hydroid he described is now believed to have been a different species from C. noliformis auct. and perhaps conspecific with C. hemisphaerica (Linnaeus, 1767). It is proposed that a neotype be designated for C. noliformis in accord with usage during the past 100 years. The species noliformis as currently understood occurs circumtropically and is common on pelagic Sargassum and benthic substrates.

The purpose of this application is to conserve the accustomed understanding and usage of the names for two genera of tanager from South America, Schistochlamys Reichenbach, 1850 and Neothraupis Hellmayr, 1936, by the designation of Tanagra capistrata Wied, 1821 as the type species of Schistochlamys (family thraupidae, or family emberizidae, subfamily thraupinae). At present T. fasciata Lichtenstein, 1823 is the valid type species of both Schistochlamys and Neothraupis.

The purpose of this application is to conserve the well known and used specific name of Ampullaria canaliculata Lamarck, 1822 (currently known as Pomacea canaliculata, family ampullariidae) for a species of freshwater gastropod. The name has been used for the taxon for nearly 180 years but is a junior primary homonym of Ampullaria canaliculata Lamarck, 1804 (currently known as Natica or Amauropsina canaliculata, family naticidae or ampullospiridae), the name for an Eocene marine species from Europe. The species have not been considered congeneric since 1832. Pomacea canaliculata (Lamarck, 1822) is a major pest species of rice and taro, originally from South America but spreading in North America and introduced in south-east Asia and islands in the Pacific.

The purpose of this application is to attribute the specific name of the puffadder shyshark Haploblepharus edwardsii to Schinz (1822) as the author and to conserve edwardsii as the correct original spelling; Schinz used the spelling edwartsii

The purpose of this application is to designate Isospora suis Biester, 1934 (family sarcocystidae) as the type species of Isospora Schneider, 1881. At present the nominal species I. rara Schneider, 1881 is the type species by monotypy, but the original material (cysts recovered from a slug, and probably of avian origin) does not exist and the species is unrecognisable from its description; it probably belonged to the eimeriidae. The name Isospora is in wide use for parasitic coccidia which are of medical and veterinary importance because they cause the disease isosporosis in mammals, including man. To stabilise this usage it is proposed that I. suis Biester, 1934, which causes isosporosis in pigs, should be designated as the type species.

The purpose of this application is to conserve the name of the Palaearctic grassfly Chlorops meigenii Loew, 1866 (family chloropidae). This is a junior primary homonym of C. meigenii Fallen, 1823, but Fallen's name has been treated as a junior synonym of Cerodontha denticornis (Panzer, 1806; agromyzidae) since 1830 and the case is referred under Article 23.9.5 of the Code
