S ummary . 1. The significance of the occurrence of biologic strains in T. dipsaci is discussed and reference made to previous work on the subject, 2. The technique by which the nematode may regularly be induced to set up an infestation in a favoured host plant is described, as is its application to the experiments made. 3. Experimental results obtained when fourteen strains of the nematode, of known history, are given facilities for entering alien host plants are presented in detail. 4. The conclusions arrived at are, that biologic strains of T. dipsaci occur, but that these strains are in some cases able to attack more than one host plant. Further, some affinity appears to exist between strains occurring in the narcissus and in the common plantains. 5. The practical application of our knowledge, in the event of a crop being attacked by the nematode, is discussed.
