You will receive replies in the 100,000 range. However, these are not
authoritative. As it just happens, I asked myself the same question about a
month ago and made a new years resolution to survey all the literature, create
a data base to prevent any double counts, and make a definitive count of all
published species. I restricted my search to Gastropoda amd Pelycepoda. I
eliminated all synonyms. I included all unidentified species published as
"sp.," "sp. aff.," "cf.," etc. reported in marine and fresh water surveys.
However, I counted these only as one half to adjust for duplicate "sp's." I
just finished about dinner time. The count was 132,306.5. Tomorow I leave
for a world wide tour to verify all material reposed in museums to be sure the
same shell species has not been given two names. I should be back home by
Sunday at which time I'll provide an update.
I hope you find this data helpful.
