The highly interesting material which forms the subject of the present 
Monograph was collected by Prof. R. Douglas Laurie during the visit of the 
British Association to Australia in 1914. We may quote his own description, 
which is as follows : — " It consists of material taken from between tide- 
mark at ' Middle Beach ' on the east side of the Island, which is the exposed 
side, i. e. without a coral reef. There is a little coral to be seen growing on 
this shore at low tide, but on the other — on the west side of the Island — is a 
coral reef quite well developed and protecting a lagoon, about a mile from 
the land. 
"Middle Beach, observation spot; Lat. 31° 31' 30" S., Long. 159° 15' 
28" E. 
" Lord Howe Island is the most southerly Pacific Island with a coral reef. 
Norfolk Island, though about 2° 30' further north, has none, nor is there one 
on the Australian Pacific coast at similar latitude. 
"The whole of the material was collected from one small beach;. from 
two different levels. 58 6, hardened coral sand and weed from rock-pools at 
lower half of the beach ; 58 c, loose surface coral sand to an approximate 
depth of J inch, from three-quarter high-tide line." 
Prof. Laurie sent us a jireliminary sample, with a view to ascertaining the 
value of the material, from 58 c, and, this having promised excellent results, 
he subsequently sent us seven bottles, which may be described as follows :— 
No. 1. In 70 7c ^It'o^ol- This had never been dried. (58 6.) 
„ 2 & 3. ,, „ This had been previously dried at 50° C. These 
yielded about 10 cc. of " floatiugs." Much byssus and organic 
material. Many species in the finer siftings, and notable specimens of 
Nubecularia bradyi, N. schauinslandi, and Discorbina polystomelloides 
in the coarser grades. 
„ 4. A small bottle containing Orbitolites only ; ranging from minute speci- 
mens up to individuals 6 mm. in diameter. Dried without heat. (oS b.) 
„ 5. Similar materialin 70 % alooliol- Never dried. (58/).) 
,, 6. A single dried specimen of Orbitolites eomplanata, with the monstrous 
rectangular secondary outgrowth. (From 58 6.)
