The total number of species arid varieties in the foregoing 

 list is sixty-three, distributed as follows : 



Holopediidae 1 



Sididae 5 



Daphniidae 16 



Macrothricidae 9 



Bosminidse 2* 



Lynceidae 28 



Polyphemidae 1 



Leptodoridas 1 



63 



It is not impossible that the forms described as Daphnia 

 Schoedleri, Sars, and D. pidex, var. pulicaria, Forbes, are really 

 the same. More than two varieties of D. Kahlbergiensis, Schdl. , 

 might have been enumerated, and almost every lake has its 

 own variety of D. hyalina, Leyd. Among the Lynceidae the 

 several varieties of Chydorus sphmricus were noted but their 

 distribution was not determined. These were the forms, C. 

 coelatus, Schdl.; punctatus, Hellich; nitidus, Schdl., and minor, 



* Besides several unidentified forms.
