Helmut added these names to the list: Capulus ungaricus Natica stercusmuscarum "Stercusmuscarum" translates more or less as "flyspeck" (the direct translation is a bit cruder, but that was probably the intended sense). What is the joke in Capulus ungaricus ("Hungarian swordhilt"), Helmut? An odd place to find a Capulus, to be sure... And who was the author of these jokes? Andrew K. Rindsberg Geological Survey of Alabama
