On Steno cypris Chevreuxi. 25 



11. Ilyocypris gibba (Rhambdor). 



Of this species, easily distinguished from the preceding 

 one by the gibbous projections of the valves, a few speci- 

 mens were raised from mud derived from the other locality, 

 viz., the swamp of Kharezas. 



Copepoda. 



12. Diaptomus. sp.? 



This is a very small species, which I cannot identify 

 with any of the forms described by M. de Guerne et 

 Richard, but which seems to come nearest to D. graciloides, 

 Lilljeborg. It was raised in two of my aquaria prepared 

 with mud from the swamp of Bon Kamera, and a consider- 

 able number of specimens preserved in spirit was also sent 

 me by M. Chevreux from the same locality. 



In addition to the above enumerated Entomostraca 

 some colonies of a fresh-water Bryozo, Plumatella repens, 

 Lin, also developed in one of my aquaria prepared with 

 mud from the swamp of Kharezas.
