(Plates XXYIIL-XXX.^) 



Among the material which has been most obligingly intrusted 

 to me for study by the Director of the Royal Natural History 

 Museum in Brussels there is a large and important collection of . 

 Fishes made by M. Maurice Storms, a cousin of the late Raymond , 

 Storms, so well known for his important contiibutions to palfe- 

 ichthyology, in the Lindi River, which flows into the Congo at 

 the Stanley Falls. As the fauna of this river had not previously 

 been explored, it is desirable to give a list of all the species repre- 

 sented in the collection, seven of which are new to science.
