2. Moina propinqva, Gr. 0. Sars. 



Moina projiii/qra, (}.(). Sars, On some Australian Cladocera, 

 raised from Dried Mud. Christiania Vid. Selskabs Forhandl. 1885, 

 p. 29, PI. 5, figs 4, 5; PI. 6. 



It is rather strange that Mr. King had not observed this spe- 

 cies, which, to judge from the great number of specimens contained 

 in the collection, must abound in some places in the neighbourhood 

 of Sydney. Mr. King describes 2 species of Moina, viz., M. kmrue 

 and M. Maclemjii. Of these the first, as I have observed at an 

 earlier date 1 ), does* not at all belong to that genus but appa- 

 rently to the genus Lathonura of Lilljeborg, and the 2nd is very 

 nearly related to the Ceylon species M. submucronata Brady, 

 both differing so markedly from the typical species, that I have 

 felt inclined to propose for them a new genus Paramoina. The 

 species represented in the collection, on the other hand, is a true 

 Moina and agrees in every respect fully with the species described 

 l»y me under the above name. 



Of this form, as has been mentioned above, a very great 

 quantity of specimens were contained in the collection, forming 

 as they did the main bulk of the contents of the tube. Most of 

 the specimens had their matrix greatly distended by ova and 

 embryos, and not a trace of ephippial formation was to be found, 

 neither any male specimens.

I have been somewhat in doubt whether my identification 

 species is correct, as the figure given by Mr. King does not fully 

 agree with the specimens examined by me. In his short description 

 1 find, however, nothing that seems to prevent an identification.
