Contribution towards the Knowledr/e'of the Freshwater Fauna of 

 the Vosges. By Dr. 0. E. Imhof. 



Of the basins upon tho chain of the Vosges, the Lake of Gerard- 

 mer, 600 metres above the sea, is as yet the only one that has been 

 investigated with regard to its fauna, and, indeed, for its Entomo- 

 straca and Hydrachnida. The determination of the material there 

 collected in July 1887 gave 16 Cladoeera, 7 Copepoda, and 16 Hy- 

 drachnida. Of forms living at tho bottom the genera Plauaria and 

 Pisidium also were named *. 



The following results of investigations may be ranged with, those 

 previously mado known from this geographical region (the Mitter- 

 sheimer-, Niederstein-, and Zummingen-Weiher in Lorraine) t.
