No reference has previously been made to tlie occurrence of Cladocera in 

 Soutli Australia; eight species are here recorded, all of which were collected in 

 the Botanic Gardens, Adelaide. 



Only one species has been recorded for Western Australia, Moina flexuosa, 

 a species described as new by Sars in 1896. 



In Tasmania, G. W. Smith in 1909 recorded eleven species, eight of which 

 were described as new. 



Preserving and Mounting. — The best preservative for Cladocera is 10% 

 glycerine in alcohol. T^his does not distort or render them brittle as do so many 

 preservatives ; they can be mounted directly from the glycerine alcohol in glycerine 

 jelly, but an excellent mounting medium can be made bj' a mixture of gum 

 arabic, cocaine, chloral hydrate and water. If a stain is required, borax carmine 

 is fairly satisfactory, after staining, the specimens arc cleared in the usual way 

 and mounted in Canada balsam. 



The writer's thanks are due to Acting-Professor L. Harrison for his interest 

 and valuable advice in the. preparation of this paper, and also to many friends, 

 who have so kindly collected material.
