Evolutionary Biology, of which this is the eighteenth volume, con tinues to offer its readers a wide range of original articles, reviews, and commentaries on evolution, in the bro~dest sense of that term. The topics of the reviews range from anthropology and behavior to molecular biology and systematics. In recent volumes, a broad spectrum of articles have appeared on such subjects as natural selection among replicating molecules in vitro, mate recognition and the reproductive behavior of Drosophila, molecular systematics ofCrocodilia, evolution of the monocotyledons, and the com munication network made possible among even distantly related genera of bacteria by plasmids and other transposable elements. Articles such as these, often too long for standard journals , are the stuff of Evolutionary Biology. The editors continue to solicit manuscripts on an international scale in an effort to see that everyone of the many facets of biological evolution is covered. Manuscripts should be sent to anyone of the following: Max K. Hecht, Department of Biology, Queens College of the City University of New York, Flushing, New York 11367; Bruce Wallace, Department of Biology, Virginia Polytechnic Institute and State University, Blacks burg, Virginia 24061; Ghillian T. Prance, New York Botanical Garden, Bronx, New York 10458.
