The helminths of South African lizards collected by Malan show a high degree of host-specificity. Among the species recorded the following are new: Paradistomum zonuri n. sp. and Thubunaea impar n. sp. from Zonurus cordylus; Oochoristica africana n. sp. from Agama hispida; Pharyngodon mabuiensis n. sp. from Mabuya trivittata; Thelandros rotundus n. sp. from Agama atra and Pseudocordylus rnicrolepidotus. Several generic diagnoses are discussed and emended. Notes are given on host-specificity, infection percentages and possible life-histories.
