Since the publication of the writer's (1932) paper on the nematode genus Anguillulina, opportunities have occurred from time to time for making further observations on the morphology and anatomy of some of the species of the genus found associated with the roots of plants. Certain of them are parasitic in roots, at least during part of their life, at other times occurring free in the soil. Others have not been found within roots but have been obtained only in water extracts of turf and their exact relation to the roots of plants is at present undetermined.
