Description of Two Additional South African 

 Phyllopoda 



With 3 autographic Plates 

 By G. O. Saks. 



Introduction. 



The two remarkable Phyllopoda described in the present 

 paper were contained in a collection of fresh water Ento- 

 mostraca kindly placed in my hands for examination, by the 

 South African Museum in Cape Town. They were both 

 in an excellent state of preservation, so that they admitted of 

 being well examined, both as to the general habitus and the 

 anatomical details. As may at once be seen from the plates 

 accompanying this paper, they are very different from any 

 of the 4 species, recently described by the present author 

 in another paper of this Journal, from Port Elizabeth. The 

 one is a Branchipodid, which evidently belongs to the 

 genus Streptocephalus, though in some points differing rather 

 markedly from the previously known species. The second 

 Phyllopod is a Limnadiid, which forms the type of an 

 interesting new genus allied to Estheria. Both these forms 

 I regard as new to science.
