Do you judge the molecular sytematics of cowries developed by C. P. Meyer
(Malacologia, 2004, 46:127-156 and references therein) insufficient or
unreliable? I would like to know a different, grounded opinion (I am not a
genetist). I could save a lot of work. After having ordered for long time my
cowries according "groups" (and few subgenera) of a single genus, being
scarcely satisfied by the plethora of genera, subgenera, species,
subspecies, forms and so on, I am now reordering them according Meyer.
