BY R. ETHERIDGE, JUN. 631 



When speculating on the geological history of Lord Howe 

 Island,* I referred to the 1000 feet submerged bank which 

 extends north-westerly from New Zealand to Lord Howe, and 

 quoted Mr. A. R. Wallace's view on the subject. I should also 

 have added that those interested in the possible oscillations of 

 old land surfaces in the South Pacific from Australia eastward, 

 and since Jurassic times, cannot do better than consult the highly 

 interesting and instructive addresses of Prof. F. W. Hutton " On 

 the Origin of the Fauna and Flora of New Zealand."! In these 

 papers a very exhaustive account is given of the possible exten- 

 sion of land around New Zealand in former times towards New 

 Guinea by New Caledonia and Fiji, reaching even to South 

 America ; besides a lucid exposition on the origin of the present 

 fauna and flora of New Zealand. 



In conclusion, I may remark that the deposit at Lord Howe 

 Island I have called the " Coral sand-rock, ":|: appears to be very 

 much akin to the " beach sand-rock " described by Dr. H. B. 

 Guppy,§ as found at the margins of coral islets around the 

 Solomon Group, and its formation seems to have given rise to 

 much speculation in his mind, as it did in mine, when at Lord 

 Howe Island. 



Addendum, 20th August, 1889. 



The original chart of Lord Howe Island, believed by us to be 



unpublished, and of which we were supplied with a tracing by 



the Deputy Surveyor-General, I find was published in Governor 



Phillip's " Voyage to Botany Bay " (4to, London, 1790, p. 183).
