The following pnper deals witli I'l-a vKin'Dtils, and extends tlie known 

 yange of several otliei- Australian ci'nstaceans. The former is represented 

 in the Australian Museum collection by several large series of specimens, 

 which afford an opportunity to give a few notes on tlie variation and 

 characters of the species. For assistance in the formation of the paper I 

 am indebted to Mr. A. R. McCulloch, whose tuition in the past has laid 

 the foundation of my work.

Hess^ has incorrectly recorded (hlasimia^ fiijinifiis aud Lj. variafiis 

 ^= tetrai/oiioii) from Sidney, but no species of the genus is known to occur 

 so far south as Port Jackson. I am now able to record the presence of 

 JJi-a in New South Wales' waters, however, a fine series of IL inarionis 

 having been recently collected by Mr. J. R. Kinghorn on a lagoon mud-flat 

 near South West Rocks, Trial Bay.
