To all interested in bivalves, particularly unionids:
I need answers/ideas on several questions asap.  Many thanks.
     1.  Does anyone have any actual expericence with, or know of published/
unpublished studies/observations, anywhere, dealing with the effects of a
bentonite slurry on mollusks  (slurry used in directional borings for
cables/pipes under rivers/lakes)?  The effects would result from the bentonite
leaking out thru a fracture in bedrock etc.
     2.  Similar vein: Does anyone know of studies/having any experience
regarding the effects of pressurized polybutene (200 psi) in cables, or
pressurized polybutene alkylbenzene (34-40 psi), both used in "pipelines"
under rivers, in the event of pipeline failure.
     3.  Does anyone know of any museum or otherwise, specimens of
Pseudomulleria dalyi (EA Smith 1898), that would give the exact locale for
this freshwater bivalve?  Haas (1969) gives the general locale as 'Mysore in
Sud-Indien, Budra Fluss" (Budra River, Mysore, India).
     Thanks.
