Cephalobus parasiticus is described from eleven out of sixteen young specimens of Macacus irus mordax (synonym, M. cynomolgus) caught in the vicinity of Batavia.
The species, which strikingly resembles and is easily capable of being confused with the rhabditiform free-living generation of Strongyloides, is found in the stomach and intestine of the monkeys but is apparently non-pathogenic. This nematode appears to be unable to establish itself in the rat and guineapig but is capable of being propagated indefinitely on bouillon agar at room temperature.
