454 MOLLUSCA OF MAST HEAD REEF, QUEENSLAND, I., 



species are here noted from Mast Head than have been observed 

 in any single area of like dimensions in Torres Strait itself. For 

 this marine fauna I have already proposed* the title Solanderian. 



Prompted by a wish to better define the distribution of the 

 East Australian marine fauna, I suggested to several friends the 

 advantage of examining the southern extremity of the Great 

 Barrier Reef. Ease of access induced us to select Mast Head R,eef 

 as the point of investigation.

 A. Liddell, H. C. Skeet, H. L Kesteven and A. R. McCulloch. 

 Leaving Sydney, 15th October, 1904, we reached Gladstone, 

 Queensland, on the 19th. There we engaged a cutter of 15 tons 

 burden, and after a rough trip landed on Mast Head on the 23rd. 

 We pitched tents ashore and spent the week collecting on the 

 reef, and dredging in its immediate vicinity. On October 31st 

 we struck camp, packed and returned to Gladstone. Sydney was 

 reached on November 7th. A popular account of our trip 

 appeared in the ' Sydney Mail' of 7th December, 1904. 



The Bunker and Capricorn Archipelagoes were visited by Prof. 

 Jukes on H. M.S. 'Fly ' in 1843, and I am not aware that any 

 naturalist has worked there since. Jukes gave a description! of 

 One Tree, Heron and Wreck Islands (not to be confused with 

 Wreck R,eef about 200 miles to the north-east). On the former 

 he noted Hippopus and Tridacna. Our party failed to find the 

 Hippopxis on Mast Head. Probably the ' Fly ' collectors 

 obtained the Scapha pulchra Sowerby, which Gray has recorded! 

 from Heron Island. Another rare Volute, V. canaliculata McCoy, 

 has been reported under the name of V. harfordi from Wreck 

 Island. § As this reef is the nearest to a trunk railway, and 

 therefore easiest to reach from the large cities of Australia, it will 

 probably be revisited by scientific folk. For their use I preface
