This list was composed because English conchologists were 
complaining of the great number of genera I was forming and 
naming, to show them that the genera used in the Museum 
collection had almost all of them been used by acknowledged 
authors, and very few of them named by me — and, at the same 
time, that many authors had written on the subject, and were 
far in advance of the Lamarckian system. Very shortly after 
the publication of this list, the genera brought together were 
adopted, and elementary books were published in different
