1988 184 p., 135 full-colour plates, hardbound. Spine slightly discoloured, else a very good copy.Part of a very useful series of, currently, ten volumes (this being the third), describing and illustrating juvenile gastropods, whose identification can be quite a challenge, especially when they resemble the adults of other, smaller species, or look entirely different from the adults of their own species (e.g., Triviidae). In all instances, both the juvenile and adult form are shown.
