Entomostraca of the Albert Nyanza. 83 



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

 must remain as the only representative of the group now 

 known from the 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 Albeit Nyanza will be obtained. 



Complete List of Entomostraca known from Albert Nyanza. 



(The letters in brackets which follow the author citation refer to the 

 collections from which the forms in question have been obtained, 

 namely: — L. = material collected by Dr. Leiper ; S. = material collected 

 by Dr. Schubotz during- the German Central Africa Expedition, 11)07- 

 1908.)

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 the lake in question has 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.
