2. Notice of the Remains of the Dinornis and other Birds, and 

 of Fossils and Rock-specimens, recently collected by Mr. 

 Walter Mantell in the Middle Island of New Zea- 

 land ; with Additional Notes on the Northern Island. 

 By Gideon Algernon Mantell, Esq., LL.D., F.R.S., G.S. 

 &c. With Note on Fossiliferous Deposits in the Middle 

 Island o/New Zealand. By Prof. E. Forbes, F.R.S. &c. 



The remoteness of New Zealand, and the long period required for 

 the transmission of specimens to England, together with the very 

 limited information we at present possess of the geology and palseon- 

 tology of that interesting antipodean colony, impart a certain degree 

 of importance to any accession of knowledge, however slight, relating 

 to the physical structure, and the ancient fauna and flora of those 

 distant islands. 



These considerations induce me to submit \o the Society the fol- 

 lowing remarks on a large collection of the bones of several species of 

 Dinornis and other birds, of rock-specimens, and of fossil shells, co- 

 rals, and infusoria, received a short time since from my eldest son, 

 Mr. "Walter Mantell, of Wellington ; and although the information 

 afforded by this collection respecting the geological structure of the 

 country is but scanty, I would fain hope that this brief communica- 

 tion will not be deemed an uninteresting supplement to the memoir 

 on the Fossil Birds of New Zealand, which I had the honour to lay 

 before the Geological Society in 1848. 



The specimens were accompanied by numerous sketches of the 

 country, find a copy of the official report on the colonial capabiUties 

 of the eastern coast of the Middle Island, from Kaiapoi to Akaroa in 

 Banks' Peninsula, and thence to the Scotch settlement at Otago, a 

 distance of about 260 miles, made during my son's exploration of that 

 tract in 1848, as Government Commissioner for the final settlement 

 of native claims. 



Such parts of this report as throw light on the geology of the 

 Middle Island of New Zealand, together with remarks on any parti- 

 cular locality, are embodied in the following extracts. As an apology 

 for the brevity of his notes, my son dwells on the arduous character 

 of a pedestrian journey through a country but very thinly inhabited ; 

 the engrossing nature of his official duties, and the limited time
