A Diagnostic Manual of Cowry Species, Subspecies and Forms

OUT OF PRINT.  This manual contains the main diagnostic shell characters of 189 species and 83 subspecies the taxonomic level of which is confirmed in a Project Intraspecific variation in living cowries (1998-2012). All the conclusions drawn in this project are based on the results of conchological studies. The diagnostic conchological information is supplemented in the Manual by discussion of the 18 main cowry forms and illustrated by more than 1,100 colour pictures.
