Abstract:
Latronema whataitai sp. n. is described from intertidal sediments of Hataitai Beach, North Island of New Zealand, and its placement within the Selachinematidae investigated using 18S and D2-D3 molecular sequences. Latronema whataitai sp. n. is characterised by relatively slender body (a = 22-25), outer labial setae and cephalic setae of similar length, anterior buccal cavity with three sets of seven teeth with larger central tooth positioned above the other six, circular amphid with faint outline, males with 12-13 precloacal supplements and spicules with pointed projection near distal end, and tail 2.0-2.6 anal body diam. long. The cuticle ultrastructure of the genus is investigated for the first time using scanning electron microscopy. Molecular phylogenies of near full length small subunit and D2-D3 expansion segments of the large subunit rRNA genes do not provide support for the division of Selachinematidae into the subfamilies Selachinematinae and Choniolaiminae, and do not support a close relationship between Latronema and Richtersia despite some morphological similarities. These preliminary results are based on a small number of molecular sequences, and therefore the current morphology-based classification remains the most tractable system for the Selachinematidae until more comprehensive analyses are conducted.

Abstract:
Wellington city is characterised by steep hilly terrain, and as such several tunnels have been constructed since the beginning of the last century to provide critical transport access in the city. These tunnels are still used today as part of the city’s transport routes, while also being an integral part of the city’s history and heritage. Wellington is among the most seismically active areas in New Zealand. Three major active faults located within the Wellington Region and the proximity to the subduction zone are the main contributors to the high seismicity. The aging tunnels were designed and constructed prior to the advent of earthquake design standards and are subject to deterioration. Hence, they require maintenance and strengthening to ensure operational integrity and resilience to earthquake and other hazard events. Authorities have been supported by the authors in managing the risk through identifying key vulnerabilities, and prioritisation and implementation of strengthening measures. Best practice investigation and strengthening techniques have been applied through the process to ensure resilience and cost effectiveness. The paper presents case histories that highlight the value of investigations and assessment in understanding the risks, and novel strengthening measures developed to enhance resilience while preserving the heritage of the tunnels. Case histories include the seismic strengthening of the Hataitai Bus Tunnel, the Northland and Seatoun road tunnels and the investigation and assessment of the iconic Wellington Cable Car tunnels.

Abstract:
Utatsusaurus hataii, an Early Triassic ichthyosaur from Japan, is represented by exceptionally well preserved materials but is poorly known because of incomplete preparation. Further preparation of the holotype and one of the paratype specimens has revealed nearly complete forefins that are pentadactyl, with no more than five phalanges in any of the digits. The first digit is not well developed, and the fifth distal carpal appears to be absent. The phalanges along the fin margin tend to be lunate; others are flattened cylinders. These findings indicate that the relationship of Utatsusaurus with other Early Triassic ichthyosaurs must be reconsidered.

Abstract:
Abstract. In this study, we investigated ostracod assemblages from the Co To Islands in northeastern Vietnam. We identified 77 ostracod species belonging to 46 genera in nine surface sediment samples and recognized three biofacies (I, II, and III) based on Q-mode cluster analysis. The dominant species of biofacies I and II were Aurila hataii, Loxoconcha japonica, and Xestoleberis hanaii, which commonly occur in seaweed beds from southern China to Japan. This is the first report on the ostracod assemblage from the open-sea area in northeastern Vietnam. We clarified that the ostracod assemblages in the Gulf of Tongking, including northern Vietnam, have a strong biogeographical relationship with East Asia seas. A new species, Loxoconcha cotoensis sp. nov., was described herein from the Co To Islands (http://www.zoobank.org/NomenclaturalActs/41d3fb9f-ae17-4215-82c1-0874a8bf1a30, last access: 3 June 2019).

Abstract:
Twenty-four species of pteropods are described from the Pliocene Miyazaki Group in the Tsuma-Takanabe district, Miyazaki Prefecture, southwest Japan. Five are new: Clio shibatai new species, Cuvierina miyazakiensis new species, Cavolinia floridana japonica new subspecies, C. itoigawai new species, and C. vendryesiana hyugaensis new subspecies.The pteropod fauna of the two lower members of the Miyazaki Group consists largely of extinct species. Whereas more than one-half of the species of the two upper members are extant.Twelve species, Limacina sp., Clio hataii (Noda, 1972), C. shibatai new species, Cuvierina miyazakiensis new species, Bowdenatheca? sp., Diacria digitata subsp. indet., Cavolinia floridana japonica new subspecies, C. cf. C. gypsorum (Bellardi, 1873), C. itoigawai new species, C. mexicana (Collins, 1934), C. rattonei Simonelli, 1896, and C. vendryesiana hyugaensis new subspecies seem to serve as good index fossils for the Pliocene.

Abstract:
The hitherto poorly known forefin of Chensaurus chaoxianensis (Ichthyosauria) from the Lower Triassic (Spathian) is redescribed on the basis of the holotype and two new specimens. The humerus resembles that of Utatsusaurus hataii but is distinctive in having an emarginated anterior margin. The anteroproximal prominence of the radius is well developed, unlike that of other ichthyosaurs. All three specimens have five metacarpals and many phalanges, but only three carpals, which are identified as the ulnare, intermedium, and fourth distal carpal. These specimens show that delayed mesopodial ossification occurred in ichthyosaurs, at least in an early evolutionary stage. Because delayed mesopodial ossification is common among diapsids and is unknown in Jurassic ichthyosaurs, it was lost during the evolution of the Ichthyosauria. The osteogenic developmental axis appears to have continued into the fourth digit, as in other amniotes. The ossification pattern provides conclusive evidence to support the suggestion that the basal element of the fifth digit in Early Triassic ichthyosaurs is a metacarpal, rather than a carpal.
