Early in 1938 the writer received a tube of nematodes from Mr. Colin Smee, Entomologist, Department of Agriculture, Zomba, Nyasaland, collected from a rotting peach fruit in which he had been trying to hatch fruit-flies. According to Mr. Smee's letter the worms had formed masses in the fruit and had also appeared on the surface as waving threads or tendrils composed of numerous eelworms massed together. The material had been fixed in glycerine alcohol and consisted of numerous adult males and females as well as large numbers of larval forms. Fixation was not good as although the gross morphology and anatomy was fairly easily discernible, some of the finer structural details were not as clear as one could have wished.
