MOLLUSCA FROM ONE HUNDRED AND ELEA^EN 

 FATHOMS, EAST of CAPE BYRON, NEW SOUTH 

 AVALES. 



By Charles Hedley, Conchologist. 



(Figs. 5-L>L>). 



Incidental to his official duties on the Coast Survey, Mr. G. H. 

 Halligan, L.S., Government Hydrographer, took, on the 10th 

 of November, 1902, a haul of the dredge in 111 fathoms, at 

 twelve and a half miles due east of Cape Byron, itself the 

 easternmost point of Australia. 



The product was at once sent to the Australian Museum for 

 examination, but constant pressure of work has delayed an earlier 

 report. 



The contents of the dredge were mostly shells and foraminiferal 

 sand. Accompanying these was an interesting Hydro-coralline, 

 identified by Mr. T. Whitelegge as Conopara tenuis, Moseley,^ 

 hitherto known only from the Kermadec Archipelago. 



Mr. H. J. Jensen has given an account of the Foraminifera 

 obtained.'^ 



A number of the shells discovered by the "Thetis" Expedition 

 recur here, thereby extending their range northwards. 



Omitting the pelagic shells dropped from the surface the knowii 

 ^tollusca taken at this station are as follows : —
