The work, of which the results are described in the following pages, was carried out in the Department of Zoology of the University of Sheffield and at the Laboratory of the Marine Biological Association, Plymouth. I wish to thank the British Association and the University of Sheffield for the use of tables at the Plymouth Laboratory, and I would also express my gratitude to Dr C. M.

The work described in this paper was carried out in the Department of Zoology of Birkbeck College, University of London, and at the Marine Laboratories at Plymouth and Port Erin. I wish to acknowledge my indebtedness to the University of London for the use of their table at Plymouth, to Birkbeck College for a grant of £5 towards the illustrations, and, in particular, I would express my gratitude to Mr Graham, under whose direction the work was carried out, for his continued kindness and help.The specimens of Lepidochitona cinereus which were used for the investigation were collected at Bangor, Plymouth and Port Erin, and also obtained from Cullercoats. Most of the material from Plymouth and one specimen from Cullercoats was infected with the Haplosporidian parasite Haplosporidium chitonis (Debaisieux, 1920) and was therefore unreliable for histological and physiological work. Specimens of Acanthochitona crinitus were collected at Plymouth, and showed no sign of infection with Haplosporidium chitonis; a few, however, were slightly parasitised with another Sporozoan. The Californian species Ischnochiton magdalenensis and Cryptochiton stelleri were obtained from Turtox General Biological Supply House, Chicago. Specimens of these species were fixed in formalin, which proved to be a poor fixative for histological work.

Preliminary Account

The researches of which the present communication contains a brief summary, were carried on during the summer of the present year, at the Laboratory of the Marine Biological Association in Plymouth, where I occupied a table by appointment of the British Association Committee. The observations were made chiefly on larvæ of Palœmonetes varians , but other species have also been included, and will be mentioned in particular instances.

Inw “An Account of the Researches on Races of Herrings carried out by the Marine Biological Association at Plymouth, 1914–15,” Dr. J. H. Orton stated that the alimentary canal of each fish investigated was preserved for the future examination of the pyloric cæca. The present note gives the results of my counting of the latter, and the accompanying table on page 328 shows the number of pyloric cæca for each individual fish enumerated in Tables III and IV of the above publication.

Gordon Jackson who had represented the British Association for the Advancement of Science; Dr R. S. Clark, a former member of the Scientific Staff of the Plymouth laboratory; and Sir Sidney F. Harmer, F.R.S., a member of Council since 1895, who had represented the Royal Society, and was a Vice-President; also Mr R. Hansford Worth and Mr Arthur W. W. Brown, Founders of the Association, the latter having been the last survivor of the original members.

INTRODUCTIONMembers of the leucosiid genusEbaliaare typical oxystomatous crabs which live on subtidal coarse sediments at depths ranging from a few metres to over 2500 m. Although this genus has an almost worldwide distribution, no studies of the population biology of any species has been made.Five species ofEbaliaoccur round British coasts (Ingle, 1980), four of which have also been recorded from the Clyde Sea area (Allen, 1967). During dredging surveys in this region, a sizeable population ofEbalia tuberosa(Pennant) was located in the vicinity of the University Marine Biological Station on Great Cumbrae Island, and regular sampling of this population over a period of two years provided the data on which this study is based.Apart from a few references to the occurrence of female crabs in berry (Lebour, 1928a,b; Marine Biological Association, 1957; Allen, 1967) and to the occurrence of larvae in the plankton (Jorgensen, 1923, 1925; Lebour, 19286; 1947; Rees, 1952; Williamson, 1956; Marine Biological Association, 1957; Bruce, Colman & Jones, 1963; Crothers, 1966), no other information on the population biology ofE. tuberosais available.

Inspection of fauna lists suggests that many authors have found difficulty in identifying the British species of Thracia, most being content to list them as Thracia spp. Examination of museum collections and even keys to identification (Ziegelmeier, 1957) shows many errors of identification. The problem was brought to notice when some specimens dredged off the Northumberland coast appeared to differ from the five species recognized as occurring in British waters. It was decided that a study of the specific differences similar to that of Holme (1951, 1959) for Ensis and Lutraria, and Allen (1954) for Nucula, would be useful.Specimens, particularly undamaged ones, of the British species of Thracia are difficult to obtain because they are both fragile and rare, and I am greatly indebted to the many people who were so kind as to give material and information for this study. These included Mr J. H. Barrett, Dale Fort Field Centre; Dr C. Burdon-Jones, Marine Biology Station, Menai Bridge; Mr I. C. J. Galbraith, British Museum (Nat. Hist.); Prof. R. A. R. Gresson, Queen's University, Belfast; Prof. L. A. Harvey, The University, Exeter; Mr N. A. Holme, Marine Biological Association, Plymouth; Dr N. S. Jones, Marine Biological Station, Port Erin; Mr A. D. Mclntyre, Scottish Home Department, Aberdeen; Mr R. McLaughlin, The University, Aberdeen; Dr R. H. Millar and Dr R. B. Pike, Scottish Marine Biological Association, Millport; Mr A. M. Tynan, Hancock Museum, Newcastle upon Tyne. I also wish to thank Dr D. A. Edwards, King's College, Newcastle upon Tyne, for assistance in matters mathematical.

Two species of Lima are known from Plymouth: Lima hians (Gmelin), the commonest species, inhabiting small patches of stones with muddy gravel at extreme low-tide mark on the north side of the Breakwater, where many individuals may be found together, and Lima loscombi Sowerby, found on the coarse grounds west of the Eddystone, Rame-Eddystone Grounds, Mewstone Grounds, Stoke Point Grounds and southwest of the Eddystone (see Marine Biological Association, Plymouth Marine Fauna, 1931). The latter is a much smaller species than the former, not so highly coloured, and much rarer. Although it is often difficult to obtain Lima hians, as it is only accessible at very low tides, it occurs in numbers in the locality cited.
