Abstract
Cephalobus parasiticus Sandground, 1939, reported from the stomachs of monkeys, is shown to resemble the sour paste eelworm, Turbatrix rediviva, so closely as to be identical with it.It is suggested that the monkeys probably acquired the nematodes by consuming fruit, or some other vegetable substance, on which the worms were living saprophagously; having been brought to the food by visiting flies.
