Nine genera, listed on pages 122–128 are recognized in the subfamily Rhabditinae Micoletzky, 1922, in place of three genera recognized by Osche (1952) in his recent revision of the genus Rhabditis Dujardin [1844] (sensu lato). Two of the genera—Pelodera Schneider, 1866 and Rhabditis (sensti stricto)—are subdivided into four and five subgenera respectively. One genus—Brevibucca Goodey, 1985—is accepted only provisionally in the Rhabditinae. The genus Neorhabditis Schuurmans Stekhoven, 1954 (syn. Pararhabditis Schuurmans Stekhoven, 1951; non Baylis and Daubney, 1926) is regarded as not belonging in the Rhabditinae

An account is given of observations on the occurrence of nematodes of the genus Meloidogyne in the Gold Coast. It includes a list of seventy-six host plants, both cultivated and wild, suitable for the sustenance and multiplication of the parasites as well as comments on the reactions of these various plant species to invasions of their root tissues. Many of the host plants listed constitute new records and the data submitted point to the conclusion that the root-knot eelworm has been long established in the Gold Coast.
