Shemitic

God's providence allowed "a downward deviation from a stock coincident with the best Shemitic or Japhetic, to the lowest negro" that even under the best paternal care might not be restored.

The early word "Shemitic" settled down to become "semitic." And among amateur chroniclers writing in the ponderous style of the town historian, it's not hard to find references to the "Hamitic race" as a way of saying "black folks." Japheth never became a common adjective, perhaps because of that thicket of consonants.
