Only two of the previous identifications of specimens considered to be teeth of Wealden mammals can be accepted without reservation. A special collecting technique including both chemical and mechanical processes facilitated the discovery of eight more Wealden mammalian fossils. Five were found in the Cliff End Bone Bed, a part of the Ashdown Beds, and the remainder in the Paddockhurst Bone Bed, a part of the Grinstead Clay.

Seventeen species of plant microfossils, made up of nine spores, six pollen grains, and two bodies of uncertain function, are described from the Kockatea Shale, a marine formation of early Triassic age, occurring in the Perth Basin, Western Australia. Nine new species are proposed and a new form genus Lundbladlspora is instituted to include certain trilete spores of probable lycopodiaceous affinities.

Triticites patulus Dunbar and Newell and Schwagerina adamsi sp. nov. from the early Wolfcampian (Permian) part of the Copacabana Group near Macusani, southern Peru, show morphological features that add new data concerning the evolution of the genera Schwagerina and Pseudoschwagerina from lineages arising within the genus Triticites near the close of the Pennsylvanian.

Mesotrypa bulmani sp. nov., Amplexopora thomasi sp. nov., Homotrypa sp. A, and Homotrypa sp. B occur in the Hoar Edge Limestone in the lower part of the Caradoc Series, near Evenwood and Harnage. These trepostome species show similarities with species from Cincinnatian strata in Ohio, Indiana, and Anticosti Island.

The type specimen of the Jurassic cidarid Cidarites moniliferus Goldfuss, recently designated as type species of the genus Eucidaris Pomel 1883, is redescribed. The species is considered to be a typical member of the genus Stereocidaris Pomel 1883. As these two genera were published simultaneously, it is recommended that Eucidaris should be abandoned in favour of Stereocidaris.

Sixteen species in twelve genera are described including the following new species, Bumastus powis-ensis, Marrolithus magnificus, M. lirellatus, Atractopyge sedgwicki, A. williamsi, and Metopolichas contractus. The fauna was collected from three small inliers of Llandeilo rocks in the Berwyn Dome, North Wales. There is a large indigenous element in the fauna, and an exotic element, in which two species appear to be from the Appalachian province, and one might possibly be from the Bohemian province. Two species are at present cryptogenetic.

Hystrichospheres are described from the Permian of Britain for the first time and are allocated to four genera and eleven species, two of which are new. Closest comparison is with other Permian assemblages but many of the hystrichospheres present appear to be virtually indistinguishable from forms known to occur in beds ranging from the Ordovician to the Eocene in age.

The calcareous structures of the triplesiaceid shell are discussed and interpreted in terms of the soft parts of the living animal. Special attention is paid to the pseudodeltidium, the pedicle tube, the muscle scars and pallial sinuses, which have received little consideration in the past. Relationships of the superfamily to other brachiopod stocks are considered. A new species of Cliftonia, C. oxoplecioides, from the Ashgillian, the earliest known for that genus, is described.

Three species (one of them new) of the ammonite genus Rasenia from the Leaver Kimeridgian of Eathie (Scotland) are described. They are of interest as being probable ancestors to different species of the one genus Aulacostephanus.

Various Cretaceous species of Polymorphinidae have irregular Jistulose end-chambers. Similar forms occur from the Jurassic to Recent. The Upper Cretaceous fistulose forms are considered to be abortive offshoots from either the chief smooth species or from the rarer ornamented forms. Their taxonomic significance and occurrence is discussed.
