part 3] jubassic eocks of new Zealand. 249 



In Prof. Marshall's company I collected from two or three 

 localities in the Hokonui Hills and from, most, if not all, of the 

 known fossiliferous localities round the shores of Kawhia Harbour. 

 Prof. Marshall also kindly lent and gave to me fossils that he had 

 collected at Waikato Heads and in the coast-section south of 

 Nugget Point in the far south-east of the South Island. 



This does not exhaust the fossiliferous localities of the New 

 Zealand Jurassic, but it represents the most important and tj r pical 

 sections and those where the fossils are perhaps best preserved. 

 If a collecting expedition could be sent to all the localities, it 

 would doubtless increase the known number of species ; but I 

 already possess a very representative series of the Jurassic fossils, 

 from which it is possible to obtain a general idea of the particular 

 marine Jurassic horizons present in the two islands. 



Prof. Emile Haug has summarized the state of our knowledge, 

 or lack of knowledge, of the Jurassic of New Zealand and adjacent 

 areas in the Southern Hemisphere. He says, dealing with the 

 Otapiri Beds which follow the Trias : — 



' The marine fossils which have been mentioned under the names of Belem- 

 ■nites otapiricus, Pleurotomaria ornata, and Tancredia truncata, remind one 

 of Liassic forms. Above come the Mataura Beds with Macrotmniopteris lata 

 and Tseniopteris daintreei.' (' Les Periodes Greologiques ' vol. ii, 1907. 

 p. 992.) 



Farther on, he says : — 



' Recent works have made known several very fossiliferous horizons in the 

 Inferior Oolite Series in several of the islands of the Malay Archipelago. 

 The analogous formations that exist in New Zealand are unfortunately much 



less well known ; A Stepheoceras of the group of humphriesianum, 



a Macrocephalites, and some belemnites of the genus Belemnopsis are the 

 only fossils on which one can rely to affirm the presence of the Inferior Oolite 

 in New Zealand.' 



Discussing the Upper Jurassic, Haug says : — 



' The presence of the Tithonian in New Zealand is certain, since Hochstetter 

 collected there an ammonite very closely related to Berriasella of Stramberg 

 (Ammonites neozelandicus). But the labours of the local geologists have 

 scarcely made clear the stratigraphical relations of the beds whence this form 

 was derived. A form described by Zittel under the name of Aucella plicata 

 is jsrobably from more ancient beds. The horizon of several Belemnopsis 

 described by Hector cannot be determined with certainty.' (Op. cit. p. 1109.) 



Referring to New Caledonia, he proceeds : — 



' The existence of the Upper Oolite in New Caledonia is founded on pakeonto- 

 logical data of small precision, since the shales which form the base of the 

 coal series, probably of Cretaceous age, only contain lamellibranchs and 

 gasteropoda that are specifically indeterminable. Piroutet cites, however, an 

 Aucella related to A. leguminosa of the Spiti Beds.' 



It will thus be seen that much remained, and indeed still remains, 

 to be investigated regarding the age of the various Jurassic deposits 

 in New Zealand, especially in the determination of the earliest and 

 latest horizons, and the question as to whether a complete or more
