Abstract does not appear. First page follows.

Parthenogenesis and syngonism3 are recognized phenomena among the Nematoda, yet in the root-knot nematode, Heterodera marioni (Cornu),4 where males do occur, their function in reproduction has been taken for granted. (Byars (1914)), however, did suggest the possibility of parthenogenesis in this nematode. (Gabriel (1926)) assumed its probability because he found several generations in one gall.
