This monograph shows in 186 colour-figures all known 26 species and subspecies of Xenophoridae. A quatro-lingual (English, German, French, Italian) determination guide helps to find the correct name, as well as the 44 b/w figures that show especially the base of the specimens, where the best discriminating features of the shells are found.
This is the first thorough treatment of this family for a long time. The book has 24 color plates that illustrate the 80 species of the Cassidae that are discussed in the text. There are also 17 species of Oocorythinae that are shown in line drawings. There are also many figures reproduced from antiquarian books concerning the shells under discussion in that part of the text. It is a well done monograph on a very popular family.
