A glance over this list shows that one of the six species discovered by Mr. Coode 

 Hore {Mastacembelus tanganicce) and six of those in Mr. Moore's first collection are 

 unrepresented in the collections subsequently made. 



Apart from many important additions to our knowledge, the collection now worked 

 out calls for the following modifications to the conclusions previously arrived at as to 

 the general character of this remarkable fish-fauna : — 



Two new generic types of Siluridas are here described, all previously known 

 autochthonous genera falling under the family Cichlidse. 



One species of Cichlids, Tilapia nilotica, of wide distribution (Jordan, Nile, East 

 and West Africa), previously known from Lake Kivu, is, with T. burtoni, also found in 

 Lake Kivu, the only non-endemic species of that family the occurrence of which has 

 been ascertained.
