This species may be distinguished from all previously described avian members of the genus by the characteristic arrangement of the postanal papillae and the unusually large number of preanal papillae in the male. Dujardinia, sp. indet. Host: Myonax grantii. Locality: Kigogo, Tanganyika Territory. The material consists of four females and several small larvae and is, unfortunately, not in a satisfactory condition to make specific identifi- cation possible. The genus, which is readily identified by the structure of its oesophagus, has previously been recorded from fishes, reptiles and marine mammals (Dugong). It may consequently be a foreign or spurious parasite in the mongoose, where its presence is to be accounted for as the undigested remains of a previously consumed reptile. Amplicaecum involutum (Gedoelst, 1916) Hosts: Bujo regularis and Dispholidus typus. Locality: Mt. Silinda, Southern Rhodesia. In addition to a small infection found in Bufo regularis, the type host of A. africanum Taylor, 1924, the same species of parasite was found in.
