See Conocoryphe trilineata, Wal- cott. This is not Triarthrus or Calymene beckii^ as asserted on page 108 of this Dictionary; for Walcott has a hundred specimens of it obtained by him on the typical field of Eastern New York; it is a blind triolobite, and belongs to the Olenel- lus {Georgian) Lower Cambrian zone^ beneath the Paradoxi- des zone; whereas Cal. or Triarthrus bechii is a Hudson River trilobite.
