fialiiiity, in a dcptli of six feof of watov. All were taken well 
away frcm the shore and it is stated (192(), ]>. 14.1) tliat none w-'n'c 
found under debris on the shore — tliou^h cnrefiilly sought for. 
This little crustacean is said also to occur in other salt lakes, ia 
the neighbourhood. 
Our specimens found near Teniiidewa were, as stated above, 
found on land, though evidently at the surface from burrows ex- 
tending down into moist salt-impregnated mud. There is no means 
of knowing whether, in wetter conditions, the animals would have 
been found actually in the water.* There ai'e, in the near vicinity, 
no salt lakes, although some exist at a distance of about 50 miles 
to the east. A few weeks earlier there had been unusual and heavy 
summer storms, and many creeks were llowing out of season, so that 
these small forms might easily have been carried for a considerable 
distance. The creek is, however, normally regarded as a salt creek, 
and was described as having been at this seaseii rather less salt 
than usual. The visible salt at the surface suggestea a considerable 
degree of salinity. It is ])ossible, however, that the sea iii Miocene 
times extetided northwards from the Bight towards this southern 
fringe of the ilurchison country, and we may perhaps regard these 
isolated forms as survivors of a dehnitely terrestrial, but coast- 
haunting form which once was distributed along the entire South- 
ern Australian shore in Mid-tertiary times and which have remaiiuMi 
as tolerant of salt as those recognised coastal forms, the Rcy])haci lae. 
*It is my custom, when taking small crustaceans from the 
borders of streams or lakes, to ascertain by experiment, whether or 
no they will survive for any length of time in water. Unfortunately, 
on this occasion the ex])ei'iment was not made, no water being- 
available. — G.U.N.
