In two previous papers inserted in this Journal I have 

 Partly published the results of a series of experiments instituted 

 with a view to obtain artificially hatched and domesticated Aust- 

 ralian fresh-water Entomostraca, the material being parcels of 

 mud collected from lakes and ponds in that remote part of the 

 world, and subsequently sent to Christiania in a dried state. In 

 first of these papers, 1 published in 1885, I described five 

 different forms of Cladocera, examined in this way during the 

 summer of 1884, whereas the 2nd paper, 2 published in 1887, 

 was wholly devoted to a more detailed account of one very re-

 ln my aquaries during that summer, and these 1 promised to 

 describe subsequently. In the present paper I propose to give
