We thank the staff at ETI (now Naturalis Biodiversity Center) for producing and supporting the Linnaeus II software that enabled us to present all these data in a coherent and attractive way on CD-ROMs, and for developing a web-based version Linnaeus New Generation in which this website is produced.

The authors are grateful to all who have contributed in any way to the CD-ROMs and this website. We would welcome corrections and suggestions for improvements, and in particular we would be happy to receive colour slides, photographs or good digital images of species not illustrated here.
