The Galway Bay area was sampled quantitatively for plankton during 1972–3. The larvae and/or post-larvae of 67 species of fish were identified from the plankton. The recorded occurrence per m3 and the percentage occurrence of the individual species is presented and discussed, and reference is made to the concurrent occurrence of various chaetognath species and copepod species. The results of previous investigations of the plankton of the Galway Bay area are mentioned.

Lycopodium complanatum L. has yielded a total of eight alkaloids, six of which appear to be new. They are complanatine (L1) (C18H31ON); alkaloid L2 (C18H29O2N); alkaloid L3 (C18H31O2N); alkaloid L4 (C16H27N); alkaloid L5 (C18H28O2N2); obscurine (L6) (C18H28ON2); the known lycopodine (C16H25ON); and nicotine. It is pointed out that this is the first recorded occurrence of nicotine in a pteridophyte. The isolation of nicotine from Equisetum arvense L. is also recorded.

AbstractThe occurrence of three accessory minerals with significant rare earth contents in Tertiary acid rocks of St. Kilda is described. Allanite, zirkelite, and chevkinite were identified by electron probe analysis (with energy-dispersive attachment) and the chevkinite confirmed by X-ray diffraction. Brief comparison is made with other Tertiary occurrences of RE minerals. This is the first recorded occurrence of chevkinite in Great Britain.

Six years ago, in a paper read before this Society, Dr. Herbert H. Thomas drew attention to the relative abundance of andahsite in the Plioeene deposits of Cornwall, East Anglia, and Kent, and also in various glacial and recent sands. When that paper was written, the only recorded occurrence of unaltered detrital andalusite in sedimentary rocks of greater age than the Pliocene was that in the Middle Chalk of Beer in Devonshire.

Proconchidium brodeurensis n. sp. occurs 212 m above the base of member B of the Baillarge Formation on Brodeur Peninsula, Baffin Island, 8 m below the Ordovician–Silurian boundary. Study of Proconchidium shows that it can be easily distinguished from Eoconchidium but possesses many characters that are similar to those in Tcherskidium. Analysis of internal structures suggests that the three genera can be distinguished from each other and belong to Virgianidae. Tcherskidiidae is a synonym of Virgianidae and should be abandoned.This represents the first recorded occurrence of Proconchidium in North America. Although this genus and its related genera Tcherskidium Sapelnikov, 1972, and Eoconchidium Rozman, 1967, are common in Ashgill strata of Eurasia, they have not been recorded or illustrated from North America. This led to the suggestion that distinct brachiopod biogeographic provinces may have existed during the Ashgill. The occurrence of these genera probably indicates that they may have lived in mostly tropical and subtropical zones.

ABSTRACTDirect fossil evidence of scavenging ostracods is rare. A convincing example, representing the earliest recorded occurrence of ostracods feeding on vertebrate carrion, is described from the Bowland Shale Formation (Kinderscoutian, Upper Carboniferous) of Derbyshire, UK. It consists of the anterior end of a shark (Orodus sp.) whose upper surface is crowded with adults and juveniles of the nektobenthic ostracod Eocypridina carsingtonensis Wilkinson, Williams, Siveter & Wilby, 2004 (Myodocopida: Cypridinidae). Extrapolation of their preserved density suggests that the entire carcass may have hosted over a thousand individuals. It presented a rare opportunity for benthic scavenging in the Widmerpool Gulf because it was sufficiently large to have protruded above the inhospitable, and probably soupy, substrate surface. Although not necessarily a necrophagous specialist, E. carsingtonensis appears to have been well adapted to rapidly locating and exploiting widely dispersed nekton food drops. Its absence from the background sediment suggests that it commuted to the shark over relatively large distances, probably from adjacent basin highs. This implies a well-developed chemosensory capability. The ostracods are interpreted as having been overwhelmed by sediment dislodged during the sudden collapse of the partially buried carcass.

A review of the native Iranian species of Lavandula is presented, including the first recorded occurrence of L. pubescens, new distribution records for L. coronopifolia, and a detailed description and observations of the poorly known endemic L. sublepidota. The phylogenetic relationships of several taxa, including Lavandula sublepidota and L. hasikensis from Oman, are investigated for the first time using molecular data (matK and ITS regions), and changes to the sectional classification are proposed.

Wood-ash stone, composed mainly of calcite (XRD, XRF, EMS and petrological determination), has been found within the remains of a large, standing and mostly burnt tree (Angophora costata) near Sydney, N.S.W. This may be the first recorded occurrence of wood-ash stone in Australia and outside North America. Slow burning of standing trees is proposed as a mechanism for producing carbonate features in nutrient poor and acidic soil parent materials such as the quartzose Hawkesbury Sandstone.
