Article Reference The Recent Typhinae (Gastropoda: Muricidae) of New Zealand.
The Recent Typhinae from the New Zealand region are reviewed. Four species are recognized: Monstrotyphis pauperis (Mestayer, 1916), M. montfortii (A. Adams, 1863), M. tangaroa n. sp. and Siphonochelus solus Vella, 1961. A possible fifth species, known from a single, subadult specimen, remains unidentified.

Article Reference New species of Muricidae (Gastropoda) and additional or noteworthy records from the western Pacific.
Fourteen species of Muricidae referable to the (sub)genera Promurex Ponder & Vokes, 1988, Pygmaepterys Vokes, 1978, Murexsul Iredale, 1915, Pazinotus Vokes, 1970, Prototyphis Ponder, 1972, Ponderia Houart, 1986, Gemixystus Iredale, 1929, Leptotrophon Houart, 1995 and Scabrotrophon McLean, 1996 are reported from New Caledonia, the Solomon Islands and Taiwan, to depths down to 1750 m. Five new species are described: Favartia (Pygmaepterys) lifouensis n. sp. from New Caledonia with range extension to the Solomon Islands, Pazinotus chionodes n. sp. and Gemixystus calcareus n. sp. from New Caledonia, Leptotrophon wareni n. sp. from the Solomon Islands and Favartia (Pygmaepterys) circinata n. sp. from Taiwan.

Article Reference The genus Pradoxa Fernandes & Rolán, 1993 (Gastropoda: Muricidae) in SãoTomé, Príncipe and Annobón.
The genus Pradoxa is revised and all the species are described, compared and illustrated. Two new species are described from São Tomé, Pradoxa gorii spec. nov. and P. urdambideli spec. nov. The radula is illustrated for P. confirmata (Fernandes & Rolán, 1990), P. thomensis (Fernandes & Rolán, 1990) and P. gorii spec. nov. The subfamilial classification is discussed and a comparative table is added in the appendix.

Article Reference Diverse assemblages of Mid Devonian megaspores from Libya.
A restudy of Devonian palynological assemblages of samples from the A1-69 borehole, drilled in the Ghadamis Basin, western Libya, North Africa has led to the discovery of numerous well-preserved megaspores amongst abundant miospores, rare acritarchs and rare chitinozoans. Thirteen samples from base to top, 1496 ft (456 m) up to 965 ft (294 m), contain the richest Devonian megaspore assemblages from northwestern Gondwana. The section is dated by a rich diverse miospore assemblage indicating the presence of the upper part of the AD pre-Lem Biozone up to the lower part of the TCo Oppel Zone, ranging from a latest Eifelian or earliest Givetian age up to a latest Givetian or an earliest Frasnian age. Seventeen megaspore taxa have been identified. Among them, two new species (Biharisporites lugardonii and Lagenicula milleri) and four new varieties (Corystisporites acutispinosus var. acutispinosus and var. bullatus, Heliotriletes longispinosus var. longispinosus and var. radiatus) are described. One new possible megaspore species is also described: Verruciretusispora labiosa sp. nov. One core sample (1293 ft, 394 m) contains several specimens of very large megaspores (ca. 1 mm), the largest known from Devonian localities (except for one specimen observed in the Givetian from Belgium). Among the 17 megaspore taxa from Libya, 6 are present on the Euramerican Continent. This observation is in accordance with previous palynological conclusions that favour the absence of palaeogeographic barriers between the Euramerican and Gondwanan continents that are suggested to be grouped together in a “Pre-Pangea” land mass.

Article Reference A Middle Devonian Callixylon (Archaeopteridales) from Ronquières, Belgium
A permineralized Callixylon trunk is reported from Ronquières, a mid to late Givetian (Middle Devonian) locality from Belgium. The specimen consists of an 80 cm long trunk adpression whose central area is preserved as a pyrite permineralization. The pyritized area is composed of a eustele surrounded by secondary xylem. Tracheids show radially aligned groups of pits separated by unpitted regions on the radial walls of tracheids. The specimen belongs to a group of species characterized by a predominance of uniseriate rays and the lack of ray tracheids. This Callixylon specimen is one of the earliest representatives of the genus. It coexists at the locality with large cladoxylopsids and provides direct evidence that the tree habit had evolved in the archaeopteridalean progymnosperms by the Givetian.
