Glyceridae, Capitellidae, Scalibregmidae, Ammocharidae and Cirratulidae are each 
represented by one species only. 
The winter quarters of the “ Aurora” were in Commonwealth Bay, Adelie Land, 
to the south of Australia; and it was here that most of the collecting was carried out. 
A small party had been left on Macquarie Island in connection with the Meteorological 
and Wireless Station, and during the two years spent here a number of Polycluetes 
and Oligochsetes were gathered around the shore. 
A few worms were also obtained by trawling off Maria Island, Tasmania, under 
the supervision of Professor T. T. Flynn, of the University of Tasmania, who had accom¬ 
panied the “ Aurora” on one of her trips to the Macquaries.
