(Plates VIII— XI.) 



The specimens dealt with in the following pages were secured by Captain 

 Hoiilt during the trawling operations of the Queensland State trawler 

 "Bar-ea-mul." This vessel worked along the entire coast between the southern 

 boundary of the State and Cairns, principally in the ship channels inside the 

 Barrier Reef, but ocea.sionallv in the passages through the reef to its outer edge. 

 Captain Hoult found the area between Roekhanipton and the Whitsunday 

 Passage to be swarming with .small fish of many kinds, but too small to be of 

 commercial value. Even the Cato .Bank in the Coral Sea, eastward of Roek- 

 hanipton, was investigated, but, though the trawl -was hauled successfully over 

 the rough coral ground, fish were not secured in payable quantities, and the 

 investigations were brought tO' an end early in 1921. Line fishing, on the other 

 hand, produced an abundance of large edible fishes, and the ship was sometimes 

 stocked up with supplies so obtained.
