Coast, collected by M. E. Deplanclies. Millions of an Avicula 
{Monoiis)^ allied to M. salinaria of Groldfuss, of which M. Bich^ 
mondiana, of Zittel, is a variety, also occur. Astarte, Turbo 
Jouaiii^ and one other ; Spirifera Caledonica ; S. Blancliesi ; 
Scyphia armata — all these arc Upper Triassic. 
M. G-arnier’s fossils, examined by M. Fischer, were pronounced 
to be Monotis ; Halolia (an Austrian species), and Mytilus 
prohlematir.its of the same formation. 
The supposed Jurassic rocks contain Nucul a near X. Ilammen 
(De Fr.) a Littorina, Cardium, and an Astarte resembling 
A. Yoltzii (Goldf ) M. Fischer believes, however, that these are 
more likely to bo Triassic also. 
AI.Munier-Clialmas names also as Jurassic, Ostrea siiblcniiellosa; 
Astarte (or Ticniadon) prceecursor ; Pellatia Garnieri and 
Cardium Caledoiiiciun. 
A large Pinna seems to represent the Cretaceous rocks. A 
tolerably full account of the G-eology of New Caledonia will be 
found in my Anniversary Address to the Foyal Society of New 
South Wales on the 12th May, 1875. 
New Zealantl exhibits abundance of proofs that Secondary 
formations exist there, and not the least remarkable fact is tliat 
Professor llochstetter in 1859 discovered there the same Avicula 
Pichmondiana as above, and Halobia Lomelll^ Avicula scdlnaria 
with Monotis, vSpirigora, Spirifera, belonging to the Triassic 
epocli. 
In my paper “ On Recent Geological Discoveries" I collected as 
much of this kind of information as I then could; but since then 
the skill and labour of the Geological Survey of New Zealand, 
under tlie direction of Dr. Hector, have produced an abundant 
harvest of scientific details ; and to the able publications and 
Eeports from that authority I may refer those who are interested 
in the development of that most intei'esting group of islands. 
They will find there ample evidence as to the existence of Triassic, 
Jurassic, and Cretaceous, as well as of Palaeozoic rocks. The 
Saurian discoveries of Mr. T. Hood Cockburn Hoovl also deserve 
commemoration ; nor must the labours and great discoA^eries of 
Dr. Ilaast be unrememhered. 
So far as the Trias is concerned, Ilochstetter’s discoveries of 
the genera and species about Eichmond have been rivalled by 
Captain Hutton in Southland, Otago, who found in 1872, on the 
Moonlight Eange, Monotis Pichmondiana (Zitt), and Ilalohia 
Lomelli (Wissm). On the Avestern slope of ITokanuis, and on 
the south side of the Wairaka Hills, he obtained the same 
species, with others, prOA'ing that the rocks are the same as the 
sandstones of Eichmond, near Nelson, and also the Triassic age 
of the deposits. {Geologg of ^oiUliland, Report of Explorations^
