Tasmanites, Tytthodiscus, and leiospheres assignable to Leiosphaeritiia, are present in Neogene shales of the Gulf Coast area of southern Louisiana, U.S.A. Seven species of Tasmanites, one species of Tytthodiscus, and two species of Leiosphaeridia are described from sidewall core samples; all except Tytthodiscus are new.

Additional bryozoan species from the Harknessella subquadrata horizon of the Hoar Edge Limestone, Evenwood Quarry, include unique inverted cone-shaped colonies of Homotrypa atveni sp. nov. and two species questionably assigned to Amplexopora, Atnplexopora? evenensis sp. nov. and Amplexopora? sp. A.

Recent studies of young silicified productaceans from the Visean limestones of Co. Fermanagh, Northern Ireland, reveal, for the first time, that their pedicle valves were commonly furnished with a structure believed to have been a pedicle sheath.

Knowledge of the supposed reproductive structures of the Solenoporaceae (Rhodophyta, calcareous algae, mostly Palaeozoic and Mesozoic) is reviewed, and then compared with evidence from a study of well-preserved Tertiary Solenoporaceae. Even in this material reproductive bodies cannot be identified with certainty. A suggested evolutionary history of the family relates the supposed reproductive processes to cell-structure, anatomy, and palaeoecology, comparing each with that of the related Corallinaceae.

A fauna consisting of numerous specimens of the ammonoid Beyrichoceras travellynense sp. nov., together with the nautiloids Mooreoceras regulare sp. nov., Vestinautilus sp., and Knightoceras? sp., is described from the Bingleburra Formation of the Gresford District, north-west of Newcastle, New South Wales. It is suggested that the fauna may be correlated with the middle to upper part of the Beyrichoceras zone of Europe.

A fossil odontoma presumably derived from Mammuthus primigenius has been collected from late Pleistocene deposits in the Yukon Territory, Canada. Odontomas are not as commonly recognized as some other pathological conditions in extinct vertebrates, but the majority of undoubted cases reported are from Pleistocene proboscideans of North America and Asia. Some reports in other mammalian orders from other regions may be questioned.

Fifteen species of palaeotaxodont bivalves are described from the upper Artinskian and Kungurian marine deposits of New Zealand. New species are Nuculopsis imperta, N. oviformis, Quadratonucula asymmetrica, Polidevcia antequadrata, Glyptoleda intricata, G. flexuosa, and G. simplicata. One new genus Nucundata is proposed, with new species N, undata, N. truncata, N. obligua, and N. prolonga. An Australian species Nuculana concinna of Fletcher non Dana is renamed Polidevcia nodulosa sp. nov.

An investigation has been made of the miospore assemblages in the coals at the bottom and top of certain Yorkshire seams and in the adjacent seat-earths and roof measures. The assemblages from the sediments are similar and are often richer in numbers of species than those from the adjacent coals. The spores provide no evidence for the existence on the seat-earths of a distinctive type of vegetation differing significantly in composition from that which formed the initial peat layer. Several spore genera do, however, show greater frequency of occurrence in the sediments than in the coals.

Belemnopsis stolleyi sp. nov. is described, based on specimens originally identified by Stolley (1929) as Belemnopsis aucklandica (Hochstetter). Adult specimens of B. stolleyi usually show secondarily deepened ventral grooves, sometimes also found in Dicoelites, and the causes of this are discussed.
