Boulenger's (1914) original description of H. pappenheimi is quite inadequate by current standards, and thus it is impossible to determine from it the morphological limits of his species. The reason for my deciding that certain specimens are ' H. pappenheimi ' is essentially an attempt to avoid unnecessary nomenclatural change. There is certainly a biologically and morphologically vaUd taxon, occurring in both Lakes Edward and George, whose characteristics are recognizable in 16 of the H. pappenheimi syntypes (4 specimens from the [] and 12 from the Berlin Museum ( lot nos. 22689 and 22697). The four [] fishes are those on which Regan [1921] based his redescription of the species). It is to these 16 specimens that I have decided the name ' pappenheimi ' should be restricted and from which the lectotype should be chosen. If any of the other syntypes was chosen as lectotype, then the name ' pappenheimi' would either fall into synonymy or would replace the name of an already established taxon. Either way, a new name would have to be found for the taxon here considered to be Haplo- chromis pappenheimi. Regrettably, the specimen illustrated in Boulenger (1914, 1915) cannot be referred to the taxon H. pappenheimi as recognized by Regan {op. cit.) or myself. It is a fish of 66-0 mm standard length, probably a female, ZMB no. 22692. As far as I can determine this fish is a specimen of H. editardii Regan. To avoid the nomenclatural changes that would follow the choice of this fish as lectotype, I have selected for that purpose a specimen from the 16 syntypes showing the diagnostic features of H. pappenheimi, sensu
