Remarkable invasion of San Francisco Bay (California, USA), by the Asian clam Potamocorbula amurensis. I. Introduction and dispersal

“…Habe (1949, and Potamocorbula ustulata has a thicker and more triangular shell than either P. laevis (thin and oblong) or P. amurensis (thin and ovate) (Zhuang & Cai 1983), although it possesses the keel and pallial sinus of P. amurensis. Habe (1977) included P. ustulata (resurrected by Zhuang & Cai) within the synonymy of P. amurensis, but he believed the name dated from Reeve (1865), rather than from Reeve (1844), and thus retained the name amurensis as the senior synonym of this species group. If Habe (1977) is correct.…”

Systematic revision of the Plectopylinae (Gastropoda, Pulmonata, Plectopylidae)

“…Godwin-Austen (1875a) claimed that the two species are identical, based on the examination of Cuming's shells, which were labelled as Plectopylis refuga. According to Gude (1914b), the same shells, which were examined by Godwin-Austen and figured by Philippi (1847), Pfeiffer (1848a) and Reeve (1854) (now NHMUK 20150360), are in fact C. leiophis. However, since Gude could not examine the type specimens of P. refuga, he was unable to recognise that the sample of Cuming contained both species.…”

The functional morphology of Penicillus philippinensis (Anomalodesmata: Clavagelloidea: Penicillidae) and the evolution of an unique muscular system in the Bivalvia

“…3) describe and illustrate the true shell valves of a specimen of Penicillus pulchrum (Reeve, 1860, species 13) (= P. penis) (Smith 1976). The shell valves of P. philippinensis are illustrated in Figure lA in relation to the adventitious tube and in greater detail in Figure lE.…”

“…The watering pot shells of the C1avagelloidea have long been of interest because of their distinctive structure and figure prominently in early malacological texts (Bruguiere 1789;Chenu 1843;Reeve 1860) and were similarly objects of great scientific interest in the 19 th century (Owen 1835;Gray 1847Gray , 1858aLacaze-Duthiers 1870, 1883. More recently, a number of c1avagelloids have been described in greater detail, for example, species of Clavagel1a (Soliman 1971;Morton 1984b), Bryopa (Appukuttan 1974;Savazzi 2000) and Dianadema (Morton 2003b) (C1avagellidae), and Brechites (Purchon 1956(Purchon , 1960Morton 1984aMorton , 2002a, Humphreyia, Foegia, Kendrickiana and Nipponoclava (Morton 1984a(Morton , 2002b(Morton , 2004a (Penicillidae).…”
