in the geological history of New Zealand. A great earth-pressure acted at its 

 close, and all the areas of Mesozoic sediments were folded and apparently 

 greatly elevated. The strike of the folds is remarkably uniform throughout 

 the greater part of the country. From Mount Cook through the northern 

 part of the South Island, and through the North Island from Cape Terawhiti 

 ■to Poverty Bay the direction is constantly north-north-east.' 



V. Relationship to the Jurassic Deposits op 

 Adjacent Areas. 



The Jurassic, as well as the Trias of New Zealand, offers a great 

 •contrast with that of Eastern Australia and Tasmania, a contrast 

 somewhat analogous to that between the Trias of the Himalayas 

 and that of Peninsular India. 



Marine fossils of Jurassic age, however, occur in Western 

 Australia, where the beds form a remanie series, reposing upon the 

 underlying schists and gneisses. The horizons represented appear 

 to be the Bajocian and the Callovian. The fossils include 

 Belemnopsis and the familiar bivalves Oxytoma munsteri and 

 JPseudomonotis echinata. 



The Jurassic of New Zealand agrees in general features with 

 that of most other regions in the great cerczm-Pacific belt. The 

 Jurassic of New Caledonia, so far as I can ascertain, is very little 

 known, but the resemblance of its Trias to that of New Zealand is 

 probably shared by the Jurassic also. Marine Lias occurs there, 

 but the horizon seems uncertain. Marine Lias is also found in 

 Borneo (Toarcian) ; Annam ; Japan (Toarcian) ; Alaska (Toarcian 

 or Aalenian) ; California ; Nevada and Oregon (Sinemurian, etc.) ; 

 Peru and Chile (Sinemurian- Aalenian). 



VI. PALEONTOLOGY OF THE NEW ZEALAND JURASSIC. 



(a) Belemnitidse. 



Canaliculate belemnites seem to play nearly as great a part in 

 the Jurassic of New Zealand as they do in that of the Moluccan 

 Islands. G-. Bcehm says l : — 



' I have collected many hundreds of them in the outcropping beds of the 

 Lower Malm, in the Island of Taliabu, and also farther east, and in the Island 

 of Misol also in outcropping beds, and have left behind many thousands 

 •uncollected.' 



He goes on to say thai? in the bed of the Lagoi Stream, in the 

 forests of Taliabu, masses of Belemnites alfuricus Boehm 

 occurred. 



In New Zealand I collected examples from three distinct local- 

 ities and horizons on the northern and southern shores of Kawhia 

 Harbour. Some of these are comparable with figures of belem- 

 nites recently issued, 2 named B. canaliculatus aucMandicus Hauer
