Abstract

This paper discusses the name Strombus muricatus and related matters. The name Strombus muricatus was introduced three times, twice by Röding (1798), in the same publication for two different species of Cerithiidae; and once by Watson (1886) for a species of Strombidae. Both Röding’s introductions are junior synonyms of species previously described (Cerithium adansonii Bruguière, 1792 and Rhinoclavis sinensis (Gmelin, 1791)) and were never used again as valid names. The name Strombus (Canarium) muricatus, as a species within Strombidae, resurrecting the unavailable Strombus muricatus of Martini (1777), as introduced by Watson in 1886, however, has been used a few times as a valid name in the 20th century. Based on the specimen that Watson had at hand, here selected as lectotype, this taxon name is removed from the synonymy of S. urceus Linnaeus, 1758 and placed as a synonym of Canarium erythrinum (Dillwyn, 1817) sensu Abbott (1960). Some notes on the type species of Canarium and the primary type of S. urceus are included. It is confirmed that C. ustulatum Schumacher, 1817 is the type species of Canarium by monotypy. Canarium orrae (Abbott, 1960) is reported from the eastern coast of Queensland, Australia, but these records are very doubtful and need to be confirmed. As the references accompanying the original description of both Strombus muricatus R. B. Watson and Canarium ustulatum are a mix of species, lectotypes for these taxa are designated. An appendix listing and discussing Watson’s references to his S. (C.) muricatus is added.

Abstract

In the 20th century, Pilsbry, Preston and Rolle published a few papers in which new species of Peruvian terrestrial gastropods were described. Some helicinids and scolodontids described in these papers were not (or seldom) figured and only briefly described, resulting in confusion about the identity of these species. In preparation of further studies into the Helicinidae and Scolodontidae from Ecuador and Peru, these species are imaged (types) and briefly revised in the current paper.

Notes on Canarium sensu Abbott. 2. On the identity of Strombus dentatus Linnaeus, 1758 with the designation of a neotype and notes on its subjective synonyms (Caenogastropoda: Strombidae)

Abstract

For a long time the nominal taxon Strombus dentatus Linnaeus, 1758, currently Tridentarius dentatus, has been a source of confusion. Herein the early sources of confusion are investigated based on literature roughly up to 1800. A lectotype for S. dentatus has been designated earlier on, but, as the specimen is not a syntype, this lectotype designation is not in agreement with the IZCN Code. To fix the identity of S. dentatus unambiguously, a neotype for this species is designated. Lectotypes for the nominal taxa Lambis dentata, a subjective synonym and secondary homonym of S. dentatus, and S. samarensis, a subjective synonym of S. dentatus, are designated. Information, on the (possible) whereabouts of specimens referred to by subsequent authors, is added. An appendix with notes on Martin Lister’s Historiae Conchyliorom is added.

Abstract

Tritia crassisculpta (Harmer, 1914), syn. Nassa dautzenbergi Harmer, 1914 (non De Gregorio, 1885), is reported from the Late Pliocene North Sea Basin in the Netherlands and Belgium. For the preoccupied name Buccinum granulatum J. Sowerby, 1815 (non Born, 1778) [= Semicassis granulata (Born, 1778)] the name Tritia waltonensis nom. nov. is proposed.

A review of Moerchia A. Adams, 1860 and Microthyca A. Adams, 1863 from the Indo-West Pacific, with the description of a new subfamily, Moerchiinae subfam. nov. (Gastropoda: Pyramidellidae)

Author: J.G.M. (Han) Raven
Basteria, 89 (1): 138-186Published:

Abstract

The shells of Moerchia A. Adams, 1860 are unique pyramidellids with a planispiral shell that have a shoulder and keel and the aperture at an angle of up to 90° from the vertical axis. In their monography on the genus, Rubio & Rolán (2014) discussed three previously described species: Mo. obvoluta A. Adams, 1860, Mo. morleti P. Fischer, 1877 and Mo. introspecta Hedley, 1907 to which they added Mo. deformata and Mo. perforata, all from the Indo-West Pacific. They overlooked Mo. biplicata P. Fischer, 1877 and Mo. mariae Jousseaume, 1898 (which were never figured) and Mo. intermedia (Thiele, 1925) and did not review the type material of Mo. morleti. Herein all these species are discussed.
The present study concludes that Mo. deformata is a junior synonym of Mo. morleti, that Mo. perforata is a junior synonym of Mo. biplicata, and that Moerchia mariae is a ‘’nomen dubium’’. A neotype is assigned for Mo. biplicata. The rows of nodules on shoulder and keel show the genus Microthyca A. Adams, 1863 to be closely related, albeit that these shells are globose with an about vertical aperture. Two species were known: Microthyca crenellifer (A. Adams, 1862) and Mi. laevis Thiele, 1925, the latter of which was never recorded after its description. Marshall (in Marshall et al., 2023) concluded Lissotesta aupouria A. W. B. Powell, 1937 also to be a Microthyca, which is herein confirmed.
For the present review numerous lots from various museums and private collections were studied, besides literature and type specimens, showing both genera to be more speciose and to have a much wider distribution than thus far known, comprising many undescribed species. Moerchia arabica, Mo. corrugata, Mo. philippinensis, Mo. zuluensis, Microthyca aotearoa, Mi. australiana, Mi. corrugata, Mi. foliata, Mi. magna, Mi. marshalli and Mi. norfolkensis are described as new species, bringing the total number of species within Moerchia to 9 and in Microthyca to 10. These two genera are interpreted to represent a single clade within the Pyramidellidae. Based on their unique features a new subfamily is herein defined: Moerchiinae subfam. nov.

A lectotype for the stabilization of the name Chama magna da Costa, 1778 (presently Lutraria magna (da Costa, 1778); Bivalvia: Mactridae)

Author: Peter W. Moerdijk
Basteria, 88 (2): 220-224Published:

Abstract

Chama magna da Costa, 1778, currently belonging to the genus Lutraria, has been considered a synonym of Lutraria lutraria, or a species of its own. It is here argued that the original description and figure is based on a species that is not conspecific with L. lutraria, but that the references accompanying the description partially refer to L. lutraria. To end this unwanted situation, the original figure is selected as the lectotype of Chama magna. By doing so, the name is stabilized and Mya oblonga Gmelin, 1791 becomes a junior synonym of L. magna (da Costa, 1778).

Pododesmus subrugosus (A. d’Orbigny, 1852) (Bivalvia: Anomiidae) from the Pliocene of the North Sea Basin

Author: Peter W. Moerdijk
Basteria, 88 (2): 246-251Published:

Abstract

In 1845, P.H. Nyst described the species Anomia? rugosa from Pliocene deposits of Belgium. This common Pliocene North Sea Basin taxon is currently attributed to the extant species Pododesmus patelliformis (Linnaeus, 1761). However, the Pliocene species is different from the extant species and hence reintroduced here under its valid name Pododesmus subrugosus (A. d’Orbigny, 1852). A lectotype is designated.

Röding’s Stromboidea (Caenogastropoda): the remains of the Bolten collection in the Museum der Natur Gotha (Germany), a critical review of Röding’s taxa, and notes on the Schmidt catalogue

Abstract

We examined the collection in the Museum der Natur Gotha (MNG) for specimens of Stromboidea, once in the collection of the German physicist Joachim Friedrich Bol­ten, first described in a sales catalogue by Peter Friedrich Röding in 1798 and subsequently auctioned in 1819. We were able to recognize nine specimens of Stromboidea originat­ing from the Bolten collection with certainty, all once in the private collection of Friedrich Christian Schmidt, that is indicated as ex Bolten in the collection catalogue of mng. Apart from that, we discovered 45 specimens acquired pos­sibly once being part of the Bolten collection. A critical listing of all Stromboidea we encountered in Röding’s sales catalogue is added. Names attributed to Bolten (= Röding) by the compiler of the catalogue in NMG are discussed. Turris operosa Röding, 1798 is the first available name for Strombus turritus Lamarck, 1822 (non Röding, 1798 nec Link, 1807) and is here recombined to Doxander operosus (Röding, 1798) comb. nov. The family-level taxon Seraphsi­dae should be attributed to Gray, 1853 and the genus-level taxon Terebellum should be attributed to Bruguière, 1798. Lectotypes are designated for ; Lambis velum; Lambis con­torta; Tibia indiarum; Turris operosa; and Terebellum lin­eatum all of Röding, 1798. There are two different printings of the Museum Boltenianum by Röding. Possible future research is briefly addressed.

Abstract

One of the syntypes of Strombus robustus G.B. Sowerby III, 1875 has been discovered in the collection of NHMUK and is designated as lectotype. The status of this species, allocated to Margistrombus Bandel, 2007, is addressed. Both Strom­bus (Dolomena) marginatus sowerbyorum Visser & Man in ’t Veld, 2005 and Margistrombus bouchet Thach, 2016 are junior subjective synonyms of S. robustus. The lectotype of S. robustus and the holotype of respectively S. (D.) m. sow­erbyorum and M. boucheti is illustrated.

The identity of Meioceras elongatum de Folin, 1881 (Gastropoda, Caenogastropoda, Caecidae)

Author: Angelo Vannozzi
Basteria, 83 (1/3): 35-38Published:

Abstract

Meioceras elongatum de Folin, 1881, has been described from “mers de Chine” (China Seas) and was never recorded thereafter. The three syntypes are not conspecific and have probably a different origin. To stabilize the nomenclature, the specimen best fitting the original description and illus­tration is here selected as lectotype. As a consequence, Mei­oceras elongatum has to be considered a junior synonym of M. nitidum (Stimpson, 1851).
