Ah ha! I pick up the gauntlet. All of the L. s. straminea I have seen came
from small creeks. L. s. claibornensis seems to get in bigger streams as
well. So I don't see L.s.s. in a big river riffle. Has L.s.s turned up in
any archeological middens around Claiborne? Somewhere in the dark recesses
of my mind, I seem to remember someone telling me that a lot of "Claiborne"
material came from elsewhere, but was mailed from there, which was close
enough for government work. For this I suggest a new type designation - the
postaltype, material mailed from the nearest city but probably collected
who-knows-where.
