212 NOTES ON A COLLECTION OF FISHES FROM QUEENSLAND, 



Mr. Morton also ascertained from an old resident and fisherman, 

 that he had observed the Ceratodus going in pairs in the months 

 of June, July, and August, that they make slight indentations in 

 the muddy bottom in from six to ten feet depth of water, in 

 which they deposit their spawn ; that the male and female seem 

 to remain near the spawn, and are then not easily disturbed ; that 

 they frequent the same places every year, and that the spawn much 

 resembles that of a frog. The same informant also says that he 

 has taken the spawn, hatched it in a tub of water, and kept the 

 young alive for some weeks.

Disk sub-circular; tail one-half longer than the body, with a 

 broad rayless fin beneath extending to the extremity. Disk in 

 the centre dark brown, covered with close minute spines and 

 with three or four round flattened tubercles in the line of the back 

 on the scapular region. Sides of disk smooth, or finely granular 

 and of a paler colour. 



Lower Burdekin. Salt water. 



In the foregoing list, I have included all the fishes taken by 

 Mr. Morton within the mouths of the Burdekin and Mary Rivers, 

 but it is evident that numbers of them are purely sea fishes, and 

 have no more right to be classed as belonging to these rivers, than 

 fishes caught in Port Jackson, have to be called Parramatta River 

 fishes. Of the 51 species mentioned, 17 are essentially sea fishes.
