Entomosiraca of the Albert Nyanzn. 83 



as I luive not been able to do so yet, the species just noticed 

 must remain as the only representative of the group now 

 known from tiio lake. 



Proceeding now to combine these records with the list of 

 forms identified by Prof. Sars from Dr. Leiper's material, a 

 complete list of the Entomostraca which are at present known 

 to occur in the Alljeit Nyanza will be obtained. 



Complete List of Entomostraca knoion from Albert JTi/anza.

It will be seen that in all only ten species have hitherto 

 been taken in Lake Albert. This is a small number when it 

 is remembered that tiie lake in question lias a superficial 

 area of some 2000 square miles, and there is every reason to 

 believe that it will be greatly increased when the lake has 

 been adequately explored from the biological standpoint.
