This is the 4th volume in this series of landshell books that focuses on the family Camaenidae. It includes 463 shells belonging to 259 species, including 20 new species and 7 named forms. As with the other volumes in the series, there is little text, but the high quality photographs, generally of several views of a single species and variations within a species, make this a useful reference guide.
The lack of text may be a drawback for some users, but the photographs are more than enough to compensate for this. The photographs are large, clear, and in color, and they show the shells from all angles. This makes it easy to identify different species and to see how they vary within a species.
The book is well-organized and easy to use. The shells are grouped by species, and each species has its own page with several photographs. The photographs are accompanied by a brief description of the species, which includes its size, range, and habitat.
Overall, this is a very well-produced book that is sure to be a valuable resource for landshell collectors and researchers.
