By these means, I have been enabled to raise from the mud, 

 and domesticate, a number of Entomostraca belonging to all 

 of the 3 leading groups, Cladocera, Ostracoda and Copepoda. 

 As might be expected, the greater number of the species have 

 turned out to be identical with well-known European forms. 

 But, as the localities do not in fact belong to the European 

 continent, I think it may be of some interest to note the 

 species briefly, and I shall do so at the close of this paper. 

 Among the species raised was a rather beautiful Ostracod, 

 which I cannot identify with any of the earlier known 

 species, and which I therefore regard as new to science. 

 The description of this form will be the chief object of 

 the present paper, and I have much pleasure in dedicating 

 the species to the distinguished French zoologist, to whom 

 I am indebted for the mud from which it was raised.

This genus was established by the present author in his 

 paper »On some Australian fresh-water Ostracoda raised from 

 dried mud«, and the species S. Malcolmsonii (Baird) was 

 there described as the type of the genus. At the same 

 time, attention was drawn to the fact, that the well- 

 known Europeau form, Cypris fasciata, Müll., ought to be 

 referred to the same genus. With equal certainty another 

 European species, Cypris Fischen', Lilljeborg, may also 

 be adduced to this genus, and as a 4th species, the Algerian 

 form described below is now added.
