I Contributed a paper to the April number of the Geological Magazine for 1900 on the geology and fossils of the Devonian rocks on the north coast of Cornwall, south of the River Camel. In the present communication I propose to notice a series of fossils which I have lately obtained from the slaty rocks of Devonian age in the parish of St. Minver on the north of the Camel, which, from Trewornan, one mile north of Wadebridge, for the lower five miles of its course as river and estuary, forms the southern and south-western boundary of this parish. The open sea-coast forms its northern and north-western boundary, extending from the easterly limit at the Cove of Port Quin, the site of an old but now forsaken fishing village, about eight miles south-west of King Arthur's Castle, Tintagel, westwards round the basaltic cliffs of Pentire Head, and thence in a southerly direction to the estuary of the Camel.

Although phylogeographic patterns of freshwater decapods elsewhere in Australia are well documented, little is known of the phylogeography and biogeography of the endemic freshwater fauna of south-western Australia. Here, the phylogeographic structure of a freshwater crayfish, Cherax preissii Erichson, 1846, was investigated to determine contemporary and historical patterns of gene flow and to examined evolutionary and biogeographical scenarios. Allozyme and cytochrome c oxidase subunit I mitochondrial DNA data were collected from 15 populations, sampled across the known C. preissii distribution. Both markers revealed a clear distinction and separation among populations occurring in the north-western and southern portions of the distribution. Inferences of allopatric fragmentation and molecular dating attributed the divergence of the aquatic fauna of these regions to periods of Pliocene–Pleistocene aridity. Connectivity appeared to be greater within each of these regions. Evidence suggested contemporary, but not ongoing, gene flow, particularly within the southern region. This was possibly facilitated by dispersal during pluvial Pleistocene periods or drainage connectivity during episodic marine regressions. The divergence and distributions of these lineages parallels patterns seen in other freshwater crayfish of the region. More explicit investigation of these and further fine-scale phylogeographic studies may contribute to the understanding of biogeography and evolution in the south-west, and may further refine currently recognised biogeographical regions.

Between May 1961 and November 1970 almost monthly visits were made to Duckpool, an exposed shore on the north coast of Cornwall, where Sabellaria alveolata (L.) is the dominant organism on low-level rocks uncovered only by spring tides. Massive colonies several feet across and up to some 2 ft thick, formed mainly of shell particles cemented together by the worms, as well as many smaller colonies and single tubes, here reach their maximum development in south-west England.Selected sites and colonies were photographed and some measured at frequent intervals over long periods of time. comparative studies of long series of colour transparencies examined closely with a binocular microscope have proved invaluable in elucidating the manner and rate of growth of varied types of colonies, their lengths of life and the manner of their ultimate destruction. Detailed histories of these selected colonies are given in this paper and reveal much that was previously unknown or only guessed.A short spawning period every year in July initiates each new generation. Experimental work, already published, had shown that individuals develop at different rates, the final stage with ability to settle being reached at any time from 6 weeks to 6 or more months, and when reached the ability can be retained for some weeks. This accords with observations on the shore, where settlement takes place in any month between late August and the following early May, or rarely June. The intensity of settlement varies enormously from year to year, there being none in some years, with slight or moderate or heavy settlements in others.

One of the key concepts of Max Weber's writings on cities was that in north-western Europe, the landed nobility and urban elites were clearly distinguished. For Weber, this was indeed a main reason to locate the occidental city in the north rather than in the Mediterranean. Christof Rolker tackles this question in his ‘Heraldische Orgien und Sozialer Aufstieg. Oder: Wo ist eigentlich “oben” in der spätmittelalterlichen Stadt?’, Zeitschrift für Historische Forschung, 52 (2015), 191–224. The in-depth analysis of one of the largest and at the same time most widespread armorials in the late medieval Holy Empire, namely that of Konrad Grünenberg (d. 1494), demonstrates that in Konstanz (where Grünenberg lived) guilds (and not the nobility) first insisted on patrilineal descent as a proof of status. Traditionally, Grünenberg is seen as a paradigmatic social climber, as he left his guild to join the society of the local nobility (called ‘Zur Katz’). Yet his sumptuous armorial, containing over 2,000 coat of arms mainly from the south-west of the Empire, does not mention any single member of this noble society. Instead, it praises the tournament societies of which Grünenberg was not a member, and highlights chivalric events in which he never participated. This, Rolker argues, indicates that armorials were not only about status already gained or to be gained, but also a manual for contemporaries to discuss the social order in a more abstract way. In his ‘Wappenbuch’, Grünenberg constantly explains why he could not join the noble societies he praised, while at the same time he ignored the ‘Zur Katz’ association of which he was a member. Therefore, Rolker concludes that it was not only members (or would-be members) of the respective social groups who knew and reproduced social codes. So the boundary between noble and urban elites was more blurred than Weber claimed – though Rolker is of course not the first to criticize Weber on this. Clearly, Grünenberg's armorial was part and parcel of a wider discussion of origins and kinship, namely patrilineal kinship that took place in several social milieux, rather than simply a book which displayed inherited status.

Since the last of my “Notes on Some Ontalio Acridiidæ” were printed, five species have been added to the list, and the number of localities for those already recorded has been considerably increased. I think,therefore, that it will make the notes more complete to conclude them with a full list of the species of this family known to occur in the Province, with their distribution as hitherto recorded.Only a small portion of the territory included in the Province of Ontario has been at all thoroughly explored by entomologists, but I do not believe there are very many native species of Acridiidæ not included in the present list. Doubtless, horvever, some of the Manitoba and Minnesota forms extend into the north-western part of Ontario, while it is extremely probable that there are unrecorded species in the south-west, and possibly a few in the east and extreme north.

This report presents the results of a historic building survey and archaeological watching brief undertaken between 1998 and 2001 during restoration work (undertaken as part of the Scottish Dance Base development) on the Flodden Wall running between Edinburgh's Grassmarket and Johnston Terrace. The Flodden Wall is the name given to the 16th-century extension of the capital's town defences, traditionally seen as having been constructed in the months following the defeat at Flodden in 1513. Prior to this project the extent and condition of this particular stretch of the Flodden Wall (the north-western boundary of the Grassmarket and a Scheduled Ancient Monument) was not fully understood. This project has shown that here the Flodden Wall and surrounding area had undergone three major phases of construction and redevelopment, from its origins in the early 16th century to the formation of a drying green (Granny's Green) to the west of the Wall in the late 19th century. In particular the results have demonstrated that the surviving southern section of the Wall here was largely rebuilt during the third quarter of the 18th century, when a complex of buildings was constructed along Kings Stables Road abutting the Wall's western face.

Abstract The paper presents the results of excavations and analytical studies regarding the taxonomic classification of a funeral site associated with the societies of ‘barrow cultures’ of the north-western Black Sea Coast in the first half of the 3rd and the middle of the 2nd millennium BC. The study discusses the ceremonial centres of the Eneolithic, Yamnaya and Noua cultures.
