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.
