Hi, John!
David Campbell wrote: "There are some Lea "types" (probably mostly merely specimens identified by Lea) in the collection of the Paleontolgical Research Institution, but none identified as "types" that were labeled "Anodonta" fragilis or marginata based on the list I have."
Maybe some Lea specimens are there but not labelled as "types". If so, then A. fragilis" may still be there.

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.
