The fauna of the continental shelf and slope between Ireland and Spain has been described by Le Danois (1948), but very little faunistic work has been carried out in the area recently. Since R.V. ‘Sarsia’ was brought into service at Plymouth there have been several opportunities of investigating that part of the slope lying to the south-west of the British Isles. It has been found that, in addition to beds of coral, quite extensive exposures of rocks, stones and gravel occur between 200 and 1000 fathoms. There is a rich epifauna in this area and barnacles are one of the dominant groups.

We examined the spatial and temporal variations of coastal and oceanic epipelagic copepods (rainy–dry seasons of 2009) in a tropical area of the south-west Atlantic. Zooplankton samples were obtained at 48 stations along six transects perpendicular to the coast, in the subsurface water between the 25 and 3000 m isobaths, by horizontal hauls using a Multinet. Abundance (42–64,753 ind. m−3), biomass (0.08–113 mg C m−3) and daily copepod production (0.17–163.20 mg C m−3 d−1) showed longitudinal and latitudinal variability. The highest values were observed over the southern continental shelf during the dry season. Temoridae, Undinula vulgaris and Paracalanus quasimodo dominated the biomass and daily copepod production during the rainy season; while Calanoides carinatus, Calanopia americana, Clausocalanidae, Temoridae, Paracalanidae and Subeucalanidae dominated during the dry season. The copepod assemblages formed four different groups: rainy season–continental shelf (1), dry season–continental shelf (2), rainy season–continental slope (3) and dry season–continental slope (4). Temperature, salinity, chlorophyll-a and suspended particulate matter explained 45% of the productivity distribution of the dominant copepod species. This study is the first attempt to examine the biomass and daily copepod production in oceanic waters in the south-west Atlantic Ocean, and it showed that copepod biomass and production in a tropical region can be relatively high compared with other regions of the world's oceans.

Celtic Sea

In the Celtic Sea, to the south of Ireland, water in some winters becomes sufficiently cooled and heavy to flow to the edge of the continental shelf and to run down the continental slope to a depth of several hundred metres. A theory of the phenomenon, termed ‘cascading’, has been developed. Three winters have been examined in detail.In February 1927 much water, heavy enough to cascade, was present in the Celtic Sea and also in the English Channel. A probable course and speed of the cascading water over the shelf has been established. Since there were few observations of salinity and temperature over or beyond the slope, and none of oxygen anywhere, the theory cannot be completely established on the basis of the 1927 observations, full though they were.

Significant Difference

The sex form of each species in the flora of the south-west of Western Australia was determined, and the proportions of the different forms compared with data available for South Australia. Although the western flora has been substantially isolated since at least the mid Tertiary, no significant difference in the proportion of hermaphrodite species from that of South Australia was found. A re-analysis of the sex forms of the flora of the British Isles was also made, and it was found that this flora has a higher proportion of non-hermaphrodite species than has either Western Australia or South Australia. The possible evolutionary significance of these observations is discussed.

In a recent number of these Proceedings, the present writer defined a type of megalithic burial chamber which was there called the transepted gallery grave, and discussed the distribution of this type in southern Britain. The transepted gallery grave (sometimes called the cruciform gallery grave, or the cruciform allée couverte) consists, as was pointed out, of a central gallery grave or allée couverte with one or two pairs of small rectangular side-chambers: in plan this type of monument resembles either a Latin or a Lorraine cross. Sometimes the gallery extends beyond the last pair of side-chambers, at others it stops flush with them. It will be remembered that we listed eight tombs of this type in England and Wales: Pare le Breos Cwm and Penmaen Burrows in Glamorgan, Nempnett Thrubwell and Stoney Littleton in Somerset, Wayland's Smithy in Berkshire, and three Gloucestershire sites—Uley, Nympsfield, and Notgrove. From the distribution of these chambers it was suggested that some of them formed the primary settlement on the shores of the Bristol Channel of a culture which subsequently spread over south-east Wales, the south-west Midlands, Wiltshire and Somerset, and which we called the Severn-Cotswold culture.It was, moreover, suggested that the origin of the transepted gallery grave in Britain, and therefore of the Cotswold-Severn culture, must be sought for outside the British Isles, and we agreed with Fleure, Forde, and Le Rouzic in deriving these early settlers on the shores of the Bristol Channel from Brittany. In 1936, when the article was written, I knew of only about half-a-dozen transepted gallery graves in France: but in the following year I discovered among the Lukis MSS. at St. Peter Port a number of plans of other transepted gallery graves in western France.

Puzzling Aspect

Saccorhiza polyschides (Lightf.) Batt. is a laminarian alga found in the sublittoral region. It is widely distributed around the shores of the British Isles and is particularly common on the south west coast of Ireland. A puzzling aspect of the distribution of the species in Southern Ireland is its absence from Lough Ine, in County Cork.
