On some West-Australian Entomostraca. 117 
In habits it exactly agreed with E. Packardi, likewise 
observed by the present author in the living state. More 
frequently it was found lying quietly on the bottom of the 
aquarium, where it had burrowed more or less deeply into 
the loose mud; but at times it was seen to make some 
rapid excursions through the water, moving about rather 
violently in different directions, the back generally upwards. 
It casts its skin several times, and a rather large number of 
exuviæ were found in the aquarium, consisting of the skin 
of the whole body with its several appendages, as also the 
inner coating of the shell.
