Hi, Harry!
Thanks for the reference. Every bit of information counts in our efforts to track down the Isaac Lea specimen. Perhaps someone on the list may have some more information that may be helpful.
All the best!

Dear Listers,
Since these transactions are on very few collector's
shelves, here is the
passage in Lea (1837: 93 third paragraph:
<

which John made
reference below.

Hi
all
I am trying to locate a shell of Pyganodon (= Anodonta)
fragilis (Lamarck
1819) that was collected in Newfoundland by Bachelot de la
Pylaie and
given to Isaac Lea, in Paris, in 1832, by Baron Férussac
(see: Lea
(1837: 93; Anon 1887) - please find these references at the
end of this
post).
I have already canvassed USNM, MCZ, ANSP, AMNH, INHS, and
UIUC, but
without success.
Lamarck's TYPE series of Anodonta fragilis, consisting
of three valves
(all collected in Newfoundland by Bachelot de la Pylaie in
the same
year), is held in the Muséum d’histoire naturelle
in Geneva.
Two additional valves, from Bachelot's same original
Newfoundland
collection, are held in the Muséum national
d’Histoire naturelle in
Paris.
And then, there is the "lost shell" (one valve or
two?) given
to Isaac Lea by Baron Férussac in 1832.
It seems possible that Lea (or some later worker) placed the
Newfoundland
shell in question in a taxon other than "Anodonta
fragilis"
(possibly "marginata")? There is some confusion in
the
literature on this point.
[Thus, the key words employed to look for Lea's
Newfoundland Anodonta
fragilis collection should probably include
"Anodonta",
"Lea", "Férussac", "Bachelot de
la Pylaie"
[there are several (published) spelling variants and
combinations of this
name], "Newfoundland", and "Terre-Neuve"
[the French
for "Newfoundland".]
If anyone can tell me where the above described "Isaac
Lea
shell" presently resides (if, indeed, it still
survives), I would be
very interested in hearing from you.
