The little town or village of Bovey Tracey, in Devonshire, nestles at the foot of Dartmoor, very near its north-eastern extremity; it is situated on the left bank of the river Bovey, about two miles and a half above the point at which it falls into the Teign, and is about eleven miles from each of the towns Exeter, Torquay, and Totnes*,—bearing south-westerly from the first, north-westerly from the second, and northerly from the last. A considerable plain stretches away from it in a south-easterly direction, having a length of six miles from a point about a mile west of Bovey to another nearly as far east of Newton; its greatest breadth, from Chudleigh Bridge on the north-east to Blackpool on the south-west, is four miles. It forms a lake-like expansion of the valleys of the Teign and Bovey rivers, especially the latter, whose course it may be said to follow in the higher part, where it is most fully developed; whilst the Teign constitutes its axis below the junction of the two streams. Its upper, or north-western portion, immediately adjacent to the village, is known as “Bovey Heathfield,” and measures about 700 acres.

Abstract New determinations of ocean tides are extracted from high-rate Global Positioning System (GPS) solutions at nine stations sitting on the Ross Ice Shelf. Five are multi-year time series. Three older time series are only 2–3 weeks long. These are not ideal, but they are still useful because they provide the only in situ tide observations in that sector of the ice shelf. The long tide-gauge observations from Scott Base and Cape Roberts are also reanalysed. They allow determination of some previously neglected tidal phenomena in this region, such as third-degree tides, and they provide context for analysis of the shorter datasets. The semidiurnal tides are small at all sites, yet M2 undergoes a clear seasonal cycle, which was first noted by Sir George Darwin while studying measurements from the Discovery expedition. Darwin saw a much larger modulation than we observe, and we consider possible explanations - instrumental or climatic - for this difference.

A taxonomic revision of the Nystiellidae from Brazil, including samples from the Rio Grande Rise, South Atlantic, was performed based on shell morphology. Five genera and 17 species were recognized. For the richest genus,Eccliseogyra, the three species previously recorded from Brazil were revised:E. brasiliensisandE. maracatu, previously known only from their respective type series, were re-examined. Newly available material ofE. maracatuexpanded the known geographic range of this species to off south-east Brazil.Eccliseogyra nitidais now recorded from north-eastern to south-eastern Brazil, as well as from the Rio Grande Rise. Three species ofEccliseogyraare newly recorded from the South Atlantic:E. monnioti, previously known from the north-eastern Atlantic, occurs off eastern Brazil and on the Rio Grande Rise; its protoconch is described for the first time, confirming its family allocation.Eccliseogyra pyrrhiasoccurs off eastern Brazil and on the Rio Grande Rise, andE. folinioff eastern Brazil. The genusIphitusis newly recorded from the South Atlantic.Iphitus robertsiwas found off northern Brazil, although the shells show some differences from the type material, with less-pronounced spiral keels. Additional new finds showed thatIphitus cancellatusranges from eastern Brazil to the Rio Grande Rise, and Iphitusnotiossp. nov. is restricted to the Rio Grande Rise.Narrimania, previously recorded from Brazil based on dubious records, is confirmed, including the only two living species described for the genus:N. azelotes, previously only known from the type locality in Florida, andN. concinna, previously known from the Mediterranean. A third species,Narrimania raquelaesp. nov. is described from eastern Brazil, diagnosed by its numerous and thinner cancellate sculpture. To the three species ofOpaliopsispreviously known from Brazil, a fourth species,O. arnaldoisp. nov., is added from eastern Brazil, and diagnosed by its very thin spiral sculpture, absence of a varix, and thinner microscopic parallel axial striae.Papuliscala nordestina, originally described from north-east Brazil, is recorded off eastern Brazil and synonymized withP. elongata, a species previously known only from the North Atlantic.

The distribution of Mesolithic sites in Wales is controlled to a great extent by the terrain, for physiographically, Wales is a highland block defined on three sides by the sea and for the greater part of the fourth side by a sharp break of slope. Geologically the Principality is composed almost entirely of Palaeozoic rocks, of which the 600-foot contour encloses more than three quarters of the total area. There are extensive regions above 1,500 feet and 2,000 feet and in the north the peaks of Snowdonia and Cader Idris rise to 3,560 feet and 2,929 feet respectively. Indeed North Wales consists of an inhospitable highland massif, skirted by a lowland plateau and cut deeply by river valleys, providing only limited areas for settlement. The hills and mountains of Snowdonia with their extension at lower altitudes into the Lleyn Peninsula, and the ranges of Moelwyn, Manod Mawr, Arenig Fach and Cader Idris, are discouraging obstacles to penetration, save for a short distance along the river valleys. To the east of these peaks are extensive tracts of upland plateau dissected by rivers, bounded on the west by the vale of the river Conway and cleft by the Vale of Clwyd. To the east of this valley lies the Clwydian Range and further again to the east these uplands descend with milder contours to the Cheshire and Shropshire plains.To the south the district merges into the uplands of Central Wales, which are continuous until they are replaced by the lowland belt of South Wales.

The precise dating and determination of the source of timbers in shipwrecks found around the coasts of the North Sea and the Baltic Sea, through dendrochronology allows us to see connections between north and  south, east and west throughout the region and to a high chronological precision. In this paper we take a look at results of recent analyses of timber from ships, and timber and barrel cargoes, to try to draw a chronological picture, from the twelfth to seventeenth centuries, of links between regions, through transport in oak ships and trade of timber. Archaeological finds of oak from timber cargos in shipwrecks and fine art objects (painted panels and sculpture) show the extent to which timber was shipped from Hanseatic towns along the southern Baltic coast, to western and north-western Europe.

In 2012, in the village Davidovac situated in south Serbia, 9.5 km south-west from Vranje, archaeological investigations were conducted on the site Crkviste. The remains of the smaller bronze-age settlement were discovered, above which a late antique horizon was later formed. Apart from modest remains of a bronze-age house and pits, a late antique necropolis was also excavated, of which two vaulted tombs and nine graves were inspected during this campaign. During the excavation of the northern sector of the site Davidovac-Crkviste the north-eastern periphery of the necropolis is detected. Graves 1-3, 5 and 6 are situated on the north?eastern borderline of necropolis, while the position of the tombs and the remaining four graves (4, 7-9) in their vicinity point that the necropolis was further spreading to the west and to the south?west, occupying the mount on which the church of St. George and modern graveyard are situated nowadays. All graves are oriented in the direction SW-NE, with the deviance between 3? and 17?, in four cases toward the south and in seven cases toward the north, while the largest part of those deviations is between 3? and 8?. Few small finds from the layer above the graves can in some way enable the determination of their dating. Those are two roman coins, one from the reign of emperor Valens (364-378), as well as the fibula of the type Viminacium-Novae which is chronologically tied to a longer period from the middle of the 5th to the middle of the 6th century, although there are some geographically close analogies dated to the end of the 4th or the beginning of the 5th century. Analogies for the tombs from Davidovac can be found on numerous sites, like in Sirmium as well as in Macvanska Mitrovica, where they are dated to the 4th-5th century. Similar situation was detected in Viminacium, former capital of the roman province of Upper Moesia. In ancient Naissus, on the site of Jagodin Mala, simple rectangular tombs were distributed in rows, while the complex painted tombs with Christian motifs were also found and dated by the coins to the period from the 4th to the 6th century. Also, in Kolovrat near Prijepolje simple vaulted tombs with walled dromos were excavated. During the excavations on the nearby site Davidovac-Gradiste, 39 graves of type Mala Kopasnica-Sase dated to the 2nd-3rd century were found, as well as 67 cist graves, which were dated by the coins of Constantius II, jewellery and buckles to the second half of the 4th or the first half of the 5th century. Based on all above mentioned it can be concluded that during the period from the 2nd to the 6th century in this area existed a roman and late antique settlement and several necropolises, formed along an important ancient road Via militaris, traced at the length of over 130 m in the direction NE-SW. Data gained with the anthropological analyses of 10 skeletons from the site Davidovac-Crkviste don't give enough information for a conclusion about the paleo-demographical structure of the population that lived here during late antiquity. Important results about the paleo-pathological changes, which do not occur often on archaeological sites, as well as the clearer picture about this population in total, will be acquired after the osteological material from the site Davidovac-Gradiste is statistically analysed.

In the classification of Romance along a northern–southern continuum the languages which exhibit patterns of active-middle alignment (notably, the HABERE ~ ESSE alternation in the perfect) are also known to have undergone the aoristic drift. This article starts from Smith’s (2016) observation that the north-western oïl varieties have maintained the preterite, while also alternating the two auxiliaries, whereas the north-eastern oïl varieties have lost the HABERE ~ ESSE alternation and undergone the aoristic drift. It is argued that the developments which have occurred in the north-western varieties are not theoretically challenging or unique within the Romània. With respect to the generalization of habere in the north-eastern areas and, less conspicuously, throughout Gallo-Romance, it is claimed that this development was engendered by the rise of a dependent-marking system which follows undifferentiated nominative alignment. It is concluded that the modern Romània exhibits a stronghold of active-middle alignment in a group of central languages, which are essentially head marking.

Two nymphs of the rare Tasmanian grasshopper Schayera baiulus (Erichson), a male and a female, have been discovered in the north-eastern and north-western corners of Tasmania respectively, thus confirming its Tasmanian provenance and suggesting a former wide distribution across the north of the island. The nymphs are described and figured. The female was reared to maturity and the adult genitalia described. The very different environments at the two capture localities are documented. The problems involved in defining the habitat requirements and securing the survival of the species are discussed.

Tibetans inhabit three major regions, Tibet proper, Khams, and A-mdo. Tibet is the region so marked on the maps; Khams is the province marked as Sikang; A-mdo does not exist as a political entity, but is divided into a number of Hsien (counties) in the north-western part of Szechwan, the south-western part of Kansu, and the area inhabited by Tibetans in Ts'inghai or Kokonor. My four years' field experience of Tibetan culture was in A-mdo on the Kansu-Ts'inghai border. My study of Tibetan folk-law, therefore, is based on conditions in A-mdo. The appended translation of “Rules of Punishment for Tibetans” (promulgated by the Manchu Imperial Court in 1733) applies mainly to Tibetans in A-mdo and secondarily to those in Tibet and Khams.
