descriptions and figures given so imperfect as not to admit of 

 any satisfactory definition of the species. The method here adopted, 

 viz., that of raising the forms artificially in aquaries from dried 

 mud, does, I certainly think, give promise to extend in a most 

 essential degree our knowledge of the exotic fresh-water Ento- 

 mostraca; and I hope to be still enabled to prosecute these in- 

 vestigations, which for a zoologist are connected with peculiar 

 interest and delight, and may perchance lead to important bio- 

 logical results. 



given by Mr. King have been reproduced. None of the species however, 

 are apparently identical with those examined by myself, a fact to be ac- 

 counted for perhaps from their having been collected in small ponds only, 

 whereas the species described in the sequel are derived from mud tåken from 

 a comparatively large lake, lying, moreover, in a wholly different region of 

 Australia.
