The earliest descriptions of Australian Phyllopoda are those of 

 the Rev. R. L. King, published in the Proceedings of the Royal 

 Society of Van Diemen's Land for 1855. Since then the list 

 has been considerably added to by various workers ; ^ but 

 frequently the want of figures and more detailed descriptions 

 than have been given, makes it almost impossible to accurately 

 identify the species. 



Our thanks are especially due to Prof. G. O. Sars for his very 

 careful rede.scriptions and figures of old species, as well as for 

 his care in presenting new ones. Besides describing some spirit 

 specimens he has received dried mud from different parts of the 

 continent and successfully hatched out in Norway a considerable 

 number of species, and given valuable information of the life- 

 history of several. 



The imporcant treatise of Messrs. Baldwin Spencer and Hall 

 on the Phyllopoda of Central Australia in the Report of the 

 Horn Expedition should also be mentioned here, wherein, besides 

 descriptions and figures of new species, records of their distribu- 

 tion and some interesting biological observations are made. 



My aim in this paper has been to present a complete catalogue 

 of the Australian Phyllopoda, including bibliographical references, 

 and redescribing and figuring more amply those that appeared 

 to need it, and of which I had specimens ; also giving sufficient 

 descriptive detail for a fairly accurate identification of each of 

 the others. Unfortunately the material to hand of the several 



1 In the Proc. Zool. Soc. London, 1886, Prof. Brady gives a list of species, not only of 

 the Phyllopoda, but all the Entomostraca known at that time.
