The nemerteans are a fascinating, common and often locally abundant group of invertebrates, yet for long have attracted the attention of only a handful of scientists. In recent years, however, increasing numbers of people have developed diverse research interests in the group with the result that our knowledge of these worms has rapidly advanced. Clearly there is a need for a regular series of international meetings where individuals working on these animals can meet to exchange ideas, review developments concerning nemertean biology and freely discuss future proposals. The first such meeting was held in Philadelphia during December 1983. Twenty-seven scientists from eight countries participated in the Second International Meeting on Nemertean Biology, held at the Tjarno Marine Biological Laboratory, Sweden, 11-15 August 1986. The meeting was divid ed into five sessions: two dealt with ecological studies, two with nemertean taxonomy, and the final session covered aspects of general biology. A total of 26 papers was presented; four, by N. Anadem, G. Berg, 1. Bierne, and 1.M. TurbeviIIe, were for different reasons not submitted for inclusion in this volume. Three additional presentations were made on behalf of B. Kulikova, E. N. WiIImer, and Z. Yin, all of whom were unable to participate in the meeting.

The dry land is one world and the wet sea is another, but the line separating them is ever-changing. Known as the intertidal zone, the area between the land and the sea is defined by the extremes of the tides. Sam Hinton provides an introduction to this fascinating zone and its contiguous waters and to some of the many creatures who make the southern California seacoast their home. This highly readable book has been for many years the handiest resource available for anyone wanting to explore that region's delights and mysteries. The book is filled with interesting anecdotes and drawings and has a thorough discussion of the natural forces¯the tides, winds, storms, currents, surf, and ocean chemistry¯that affect near-shore animals. Also included is a section relating the ocean forces to the intertidal habitat, along with a map of southern California locations where one might observe the organisms described in the book.
