Isoetes jarmaniae sp. nov. is described as a new lycophyte endemic to Tasmania, Australia, where it is confined to peat-bound karstic wetlands in several river valleys in the south-west wilderness. While seemingly morphologically closest to I. drummondii, this quillwort has features that are globally uncommon in Isoetes and unknown in other Australasian taxa. Most notable are its markedly flattened, strongly recurved leaves and disproportionately large sporangium ligules that are more suggestive of South American than Australian taxa. As well, the exceptionally thin and wide (alate) megaspore equatorial ridge is swollen at suture intersections, presenting a slightly triangular shape suggestive of the Indian taxon I. udupiensis. The microspores of I. jarmaniae exhibit exceptionally, perhaps uniquely, fine-papillate ornamentation. An original key placing I. jarmaniae in context with the other Tasmanian Isoetes species is provided. This diminutive, apparently diploid species is evidently maintaining a self-sustaining population within a regionally unique habitat and small geographic range.

The author remarks that the existence of Annelida during the Palæozoic formations is manifested in two conditions. In the one, we have the shelly envelope which invests the order Tubicola, in the form of Seapolites; and in the other, the tracks of the orders Abranchia and Dorsi-branchiata are found impressed on deposits which were, at one time, in a sufficiently soft state to receive the impressions of the wanderings of these animals.Among the strata which have hitherto afforded annelid tracks, those which, in the county of Clare, represent a portion of the equivalents of the Millstone Grit, contain such tracks, in their most perfect state of preservation in great abundance; and these strata also furnish evidence concerning the circumstances which prevailed during their deposition.

The American excavators in the south-west area of the Forum at Corinth have revealed an intriguing architectural complex, which they have called the ‘Punic Amphora Building’. Evidently it housed a thriving import business with a speciality in fish and wine, whose trade extended in one direction to Sicily and perhaps Spain and in the other to Chalkidike and Chios. Masses of fragments of Punic and Chian amphoras were found crushed and pounded in the make-up of successive floor-levels in the courtyard, together with numerous pieces from Mende and elsewhere. Many others emerged from the single floors of most of the rooms or were discovered in the littered debris from the final phase of occupation. The life of this business house was somewhat short, but a domestic building on the same site had earlier been partly devoted to the same trade. All this activity ceased with dramatic suddenness; the emporium went out of use and in the late fifth century it was overlaid in one area by a new road. The end seems to be securely dated c. 430 B.C. by Attic black-glaze pottery in the final floor-level or in the debris covering the last floor. Professor Williams plausibly links the collapse of business with the interruption of Corinth's trade caused by the outbreak of the Peloponnesian War: one of Athens' first war measures was to blockade both the Saronic and the Corinthian Gulfs. This new material evidence for Corinthian commerce is most welcome in itself and, as I hope to show in this paper, it may help clarify other problems.

Borobudur temple has been famously known as one of the Indonesian heritage masterpiece. Various aspects of it had been studied thoroughly since the beginning of 20th century A.D. Those studies tended to be monumental centric, giving less attention to the cultural context of the temple and its surroundings. Settlement in the nearby places is one of the topics which not have been studied much yet; leaving a big question about how the settlement supported continuity of many activities in the temple, or even the other way around; how the temple affected the settlement. There is only a few data about old settlement found in situ in Borobudur site, only abundance of pottery sherds. The analysis applied on to the potteries find during the 2012 excavation had given some information about the old settlement in Borobodur site. The old settlement predicted as resided in the south west area, in the back side of the monument.

Ronald George Hatton was a distinguished pomologist, an able administrator and a man who won the affection and esteem of his friends and colleagues alike. Ronald was born on 6 July 1886, in Yorkshire, a county for which he always retained a great affection. He was the youngest child of Ernest Hatton who was a barrister of the Inner Temple. Ronald’s mother was Amy Pearson, a woman of forceful character who came from a similar environment, since she was the daughter of William Pearson, also a barrister, who had taken silk. With such legal forebears on both sides of the family it would scarcely have been surprising if their son had followed the law, but perhaps this hereditary influence manifested itself, in later life, in a marked ability for administration and the handling of finance. But, though Ronald’s ancestry was mainly non-scientific, there was one very distinguished scientist on the mother’s side, namely his uncle, Professor Karl Pearson, F.R.S., the famous statistician and author of The grammar of science . The other members of the family were two sisters. The elder of these, Margerie, followed a successful career as a nurse. She became Matron of the Cottage Hospital at Lyme Regis and, later, for a period of thirteen years till the time of her death, was Matron of the hospital at Teignmouth. The younger sister, Dorothy, studied modern languages at Exeter and was indeed the first woman to receive the Batchelor of Arts Degree from the, then newly established, College of the South-West. She next turned her attention to chemistry, though at this time and subsequently, after her marriage, outdoor pursuits always claimed her great interest.

Two vases, a cup and an oinochoe, from Arkesine in south-west Amorgos are published for the first time. It is argued that both are probably Middle Protogeometric, one an import from Euboia, the other from the south-east Aegean; chemical analysis supports both attributions. Their implications for the early history of Amorgos are discussed.

Almost due west of Mozambique Island, at a distance of about forty-two miles from the sea, the military road from Mosuril to Nampula crosses the Ampwihi River, an important tributary of the Monapo. During the dry season the stream is reduced to a string of stagnant pools, separated by long reaches of sand and gravel that here and there are interrupted by outcrops of the underlying formations. Throughout the greater part of its course the Ampwihi flows through a region in which gneisses persist with monotonous regularity, the only variation being that due to occasional intrusions of granite and of still later pegmatite dykes. At the point where the military road crosses the narrow channel a welcome diversion is introduced by the presence of a dark compact dyke about 10 feet in thickness. The dyke appears on the right-hand bank and crosses obliquely to the other side, taking a N.N.W.–S.S.E. course across the strike of the older rocks. Upstream, about seventy yards to the south-east, the Ampwihi bends to the south-west, so that it returns towards the dyke, which is again exposed across its sandy floor. The dyke was traced by Mr. E. J. Wayland in July, 1911, for a distance of altogether 200 yards, and was examined by Mr. D. Alex. Wray and later by myself during the same year. It is clearly the latest rock of the district, and is intruded along a line of fault, for in two cases pegmatite dykes seen on the eastern side are broken across and reappear on the western side with a well-marked northerly displacement.

The pollen grains of 300 species of 71 genera of the family Myrtaceae have been examined and their characteristic features summarized in tabular form. The investigation has been mainly concerned with those species that occur in the south-west, Pacific area, particularly Australia. For comparative purposes, the pollen morphology of a limited number of South American and two South African species has been included. The significance of pollen characters for distinguishing genera and species within the family is discussed. In some instances pollen morphology has provided additional evidence for the classification of certain species as suggested by taxonomists. A provisional key to pollen grains of the genera examined has been included.

Densities of phyllosomata of Panulirus, Scyllarides, Parribacus and Scyllarus were measured by plankton sampling in November–December 1996 and 1997 in the lagoon, in a passage through the barrier reef and above the outer slope to the south-west of New Caledonia. A total of 1017 phyllosomata were caught: 584 Panulirus, 66 Scyllarides, 6 Parribacus and 361 Scyllarus. More phyllosomata of Scyllarus spp. were caught in the lagoon than at the other two sites. The larval development of certain Scyllarus species can occur entirely in the lagoon, but morphology of the early stages of the four Scyllarus species caught here was too similar to permit conclusions about specific strategies. Phyllosomata of the Panulirus spp., Scyllarides spp. and Parribacus spp. develop only in the ocean. High densities of Stage I of Panulirus ornatus larvae caught in the passage and nearby ocean suggested that the reproductive adults of this species migrate from coastal areas towards more oceanic areas to hatch their phyllosomata. Stage I phyllosomata of Panulirus and Scyllarides were near the surface and would be carried quickly from the lagoon by the current, whereas this behaviour was not shown for Stage I phyllosomata of Scyllarus sp., and this would probably limit their passive wind drifting.

In 1906, Clarke described C. hypsipedos based on specimens of Weberbauer 2617 and placed this species in subgenus Vignea. In 1909, Kükenthal also described the name C. umbellata var. depressa on the basis of the number Weberbauer 2617, a species attributed to section Acrocystis of subgenus Carex. Wheeler in 1988 also placed C. hypsipedos in section Acrocystis while reducing Kükenthal’s name to synonymy. During a recent herbarium survey, we studied syntypes corresponding to Weberbauer 2617 at B, F, G, and MOL. The study of these materials revealed important inconsistencies between the specimens and Clarke’s protologue and Wheeler’s study, suggesting that Weberbauer 2617 is a mixed collection of two different species. One plant conforms to Carex sect. Acrocystis, while the other bears resemblance to subgenus Vignea. Several salient characters distinguish these two taxa from each other, most notably including: stigmas 3 vs. stigmas 2, achenes trigonous vs. lenticular, and perigynium pubescent to puberulent vs. glabrous. Carex hypsipedos from Peru, corresponding to Clarke’s original description, is here lectotypified. The Carex sect. Acrocystis species is assigned a new name, Carex punicola, from Argentina, Bolivia, and Peru (South America). In addition to Wheeler’s (1988) observations, we here provide additional detail and illustration of this species. It is closely related to C. geophila, another American species in section Acrocystis.

Opening ParagraphThe Ethiopic syllabary employed for writing the classical Ge'ez and also, with certain modifications, the contemporary South Semitic vernaculars of East Africa, was formed by super-imposing a system of auxiliary vowel-marks upon a basic consonantal alphabet; this alphabet occurs, alongside of the syllabic script, in the Old Ethiopic inscriptions of the Axumite Kingdom in the fourth century of our era, and is a derivative of the Sabaeo-Minaean or Old South Arabic script found in the monuments of the south-west Arabian kingdoms. But although the Ethiopic syllabary is thus genetically connected with the other main branches of the Semitic alphabet, the traditional order of the signs, in which the consonantal component and the accompanying vowel are the primary and secondary determining factors respectively, does not agree with that of any Semitic alphabet hitherto known. There is no old or reliable native tradition as to the reason underlying the order of the signs; no help is to be had from numerical signs, which elsewhere, as will shortly appear, afford valuable testimony to the order of the letters; for Ethiopic borrowed Greek alphabetic signs for this purpose, while the South Arabian inscriptions used single strokes for the units, and for higher denominations the initial letters of the native words for five, ten, hundred, &c. The mnemonic word-groups reconstructed by Bauer and others are open to objection on grounds of language and sense. Other external criteria yield only tentative and inconclusive results, and the subject has accordingly remained one of speculation and controversy.
