The distribution of about 80 species of medusae from the Scottish and neighbouring areas over the periods 1935\–1939 and 1946\–1968 is given. A method of charting has been adopted to give an average picture over the 28-year period so as to reduce as far as possible the effects of variations in annual and seasonal sampling intensity. When the occurrence of a species has, in any one year, been particularly different from the average this has been noted in the text and it is hoped that the average picture given here can be used as a basis for comparison in future years.

In July 1976 six rocky littoral sites and eight rocky sublittoral sites in Lewis and Harris were sampled for polychaetes. The sites ranged from those on the exposed west and north coast to more sheltered east coast sites.

A total of 107 species were recorded during the survey and are presented in an annotated species list. Syllidae are the dominant family both in number of species and number of individuals present, although the Serpulidae, Spionidae and Sabellidae are also well represented. Similarity of habitats sampled at different sites makes it possible to relate differences in species composition to the conditions prevailing at these localities. Such comparisons are made for four habitats\—Corallina officinalis, sediment under stones on the shore, Laminaria holdfasts and the upper shell valves of Pecten. Twenty polychaete species were found in the C. officinalis habitat, 24 species in sediment under stones on the shore, 61 species in laminarian holdfasts and 22 species on the upper shell valves of Pecten.

In general the sublittoral macroinvertebrate fauna, although lacking the Lusitanian elements found in the warmer waters of south-west England and Ireland, was found to have a high species diversity and to exist in an environment virtually free from man-made pollution.

The abundance and composition of the macrofauna of Outer Hebridean beaches is determined mainly by the degree of exposure to wave action. Most of the beaches are on the western seaboard, many without any form of shelter, and thus receive the full force of the Atlantic swell.

Twenty principal sites in Lewis and Harris were sampled for intertidal macrofauna.

Beaches of open aspect are populated by amphipods and Eurydice pulchra with very low densities of polychaetes. The sands of the Minch coast and some of the western beaches which are sheltered by islands or headlands usually have a Tellina\–Nephtys association, with a tendency for Tellina tenuis to be replaced by Donax vittatus with increasing shelter. Very sheltered inlets and the fords of the Uists have a well-developed Cerastoderma-Macoma association, while Traigh Mhor in Barra, dominated by Cerastoderma edule, has the richest fauna of any beach in the Outer Hebrides.
