In 1899 the East African streptaxid Ennea (Gulella) fortidentata E.A. Smith, 1890, was wrongly incorporated by Smith in the Mollusca checklist of “British Central Africa” [now Malaŵi]. Preston showed in 1913 that Smith’s material represents a new species, E. nyikaensis Preston (here figured for the first time), thereby deleting the former from the list. Now the real Gulella fortidentata has turned up in Malaŵi, considerably extending the range of the species. On the other hand, G. nyikaensis has not been found since its description – it is probably a local endemic still awaiting rediscovery. However, a doubtful lot from the Misuku Hills is discussed in detail. The somewhat similar G. cruciata (Von Martens, 1900) (described from a locality in Tanzania close to the Malaŵi border and here figured for the first time) is also new to the Malaŵi list and occurs in the Misuku Hills and on the Nyika Plateau.
