Tn tho thi-oe (ollowiufi liorizons very large species of Spiriferina and 
S'pirigera, belonging cliieHy to tlie group of Sp. Wrei/i Zitt., predomi- 
nate. From the nppermost of those three horizons all the ammonites 
hitherto known have been (;olleeted. Besides Rhucophi/llites cf. naoju- 
rensis (^nenst. and Sfenarcestes nov. sp. ind. described by E. v. Mojsiso- 
vics (Ammonites triasi(pies de la Nouvelle Caledonie, Compte Rendu 
Acad, des Sciences, Paris, 18, Novembre 1895), several indeterminable 
species of Arcestes have been found hy Piroutet, among them repre- 
sentatives of the groups of intaslahlati, hicarinati, coloni, sublabiali. 
This cephalopod-bearing horizon is overlaid by a bed containing 
numerous bivalves, among them Hnlobia austriaca Mojs., //. cf. Suessii 
Mojs., H. cf. celtica Mojs., H. cf. coinata Bittn. Those species point to 
the carnic stage as decidedly as the ammonites of the preceding horizon 
to the noric stage. In the topmost beds of this division an amalgama- 
tion of carnic and noric elements seems to exist, which recalls the 
two different faunae — one with carnic and the other with ]ioric affinities 
— in the Tropites limestone of Byans. 
The highest division of the Trias in New Caledonia agrees with the 
middle one lithologically, if we except the occasional intercalation of 
calcareous sandstones, but is of very considerable thickness (about 1,800 
metres). It has yielded Halobia rarestriata near its base and Pseiidomo- 
notis Richmondiana in the upper part of the series, together with plant 
remains. It is only in this horizon of undoubtedly noric age, that the 
Alpine fauna is replaced entirely by an element characteristic of the 
Arctic-Pacific province. 
The affinities of the Triassic faunte of New Caledonia with the 
Indian and Mediterranean faunae are so close, that the Trias of this 
island can scarcely put in a claim for being separated from the Indian 
Triassic province as a special faunistic district. 
No more recent data are available respecting the Triassic deposits of 
New Zealand, which belong to the noric stage. In South America the 
presence of the marine Trias has been denied altogether by Steinmann,' 
who examined the section of Utcubamba in Peru, where the fossils 
reported hitherto as Triassic had been collected. Those fossils, which 
had been assigned to the Upper Trias by E. v. Mojsisovics [Pseudomo- 
notis ochotica, Metasibirites, Helictites) have their habitat in a bed
