7. Haplochromis adolphi-frederici, Bouleng., 1914. 

 Tilapia adolphi-frederici, Bouleng. Cat. Afr. Fish. iii. p. 220, fig. 143, 

 Apparently differs from H. graueri in the longer pectoral 

 fin. The coloration is of the ''bicolor" type, irregular black 

 bars extending on to the vertical fins ; but I have found in 

 the Lake Victoria Cichlidas that this occurs in individuals of 

 several species.
