4 GL O. Sars. 



of the Scientific Society of Christiania a short account of 

 the contents of the tube. Some years afterwards, several 

 additional samples preserved in spirit were kindly for- 

 warded to me by Mr. Whitelegge, who collected them from 

 several places in the neighbourhood of Sydney, and recently 

 a number of samples of dried mud have also been kindly 

 sent to me by the same gentleman. With this mud I have 

 made, in the course of the past summer, a series of hatching 

 experiments, and have thereby been enabled to examine the 

 greater part of the species also in the living state. Of the 

 Phyllopoda I have already in this Journal given a detailed 

 account accompanied by autographic plates, and propose 

 now to give a similar account of the other Entomostraca. 

 The number of species examined amounts to no less than 

 42 in all, 26 of which have been examined in the living 

 state. As several of these species have already been de- 

 scribed and figured in detail by the auther in previous papers, 

 some from the northern part of the country, some trom 

 New Zealand, these forms will be only briefly mentioned in 

 the present paper, whereas descriptions and figures will be 

 given of the remaining species. 



The plates accompanying this paper have been prepared 

 with the greatest care by the autographic process, and 

 I am glad to see that the printing of the plates has been 

 more successfully accomplished than has been the case with 

 the plates of some of my recent papers.
