Lister was the first arachnologist and conchologist. This work was the first organized, systematic publication on shells. In spite of the wording of the title, the work contains four sections on spiders, land snails, freshwater and saltwater molluscs, and fossil shells.  In the first section Lister wrote of the many mistakes of previous authors writing on Arachnidae, to their venom and their use (!) in therapy. He provided a classification of British spiders preceding the second chapter of the first part, describing the different species of spiders according to their aspect and their alimentary habits. An appendix to this work was published in 1681.
