On Fresh-water Entomostraca. 75 



Remarks. — Although Mr. Kiug would seem io have 

 comprised several species under the above name, 1 think I 

 am right in restricting the specific denomination proposed 

 by that author to the present species, all the other forms, 

 with which I am acquainted, having turned out to be 

 identical with well-known European species. The present 

 species is a very distinct one, differing, so far I can judge, 

 from all the other known forms. For want of room on the 

 plates, I have not been enabled to give any figure of this 

 form, but I hope, that the above diagnosis will suffice 

 for easily recognizing the species. 



Occurrence. — This form was found in 4 different 

 samples, the localities of which are as follows: Waterloo 

 Swamps, Centennial Park, waterholes at Bourke Street, and 

 «Near Sydney». It was not hatched in my aquaria. 



38. Cyclops albidus (Jurine). 



Syn. C. tenuicornis, Glaus. 



A few specimens of this well-known European species 

 were found in a sample from the Centennial Park. 



39. Cyclops Leuckartii, Claus. 



Numerous specimens of this form were picked up from 

 3 different samples, the localities of which are as follows: 

 Centennial Park; Bourke Street; Waterloo Swamps; water- 

 holes at Bourke Street. 



40. Cyclops serrulatus, Fischer. 



Found rather abundantly in 2 samples, the one from 

 the Centennial Park, the other from the Waterloo Swamps. 

 It also developed in great numbers in my aquaria.
