thought to be purely a lapse, these species are not 
included in the systematic part of that publication 
(Lohmann 1893) and no Australian record is given 
in Lohmann (1901). 
The present knowledge of halacarids from 
Australian shores represents only scattered bits of 
information; the number of shore lines visited and 
habitats surveyed is small. In respect to Agauopsis, 
eastern and western Australia have no co¬ 
occurring species. The two species of Halacaropsis 
are sibling but distinct species. It is reasonable to 
expect distinct faunas in western and eastern 
shores of southern Australia. 
ACKNOWLEDGEMENTS 
The material described was collected during the 
Fifth International Marine Biological Workshop 
organized by Dr F.E. Wells. Flis help and that of 
other participants in the workshop is 
acknowledged. Thanks are also due to Drs H. 
Dastych, R.B. Halliday, J. Otto, and R. Smiley for 
loan of halacarid specimens lodged in the 
Zoological Museum in Hamburg, the Australian 
National Insect Collection and the United States 
National Museum of Natural History.
