PREFACE.


In Professor Sars' "Crustacea of Norway," quite a number of the British
species of woodlice are figured in detail and described in English, but
few copies of this fine work are to be met with in our country. The
Rev. Canon Norman has from time to time published notes on the British
species in "The Annals and Magazine of Natural History;" these are,
however, scattered, and contain but few figures, while other literature
that exists
