sperms also occur there *. The reptilian remains occur above the 

 beds with dicotyledonous leaves at the Waipara, and they occur 

 above the beds with Belemnites australis at Amuri Blutf ; but the 

 relation of the Belemnite beds to the leaf-beds has not yet been 

 made out. Mr. A. M^Kay reports having found Ammonites at the 

 Ten-mile Creek near Grreymouthf, and also near Waimirima, between 

 Cape Kidnappers and Cape TurE again on the east coast of Wel- 

 lington J. He also mentions finding a skeleton, apparently reptilian, 

 at Lake Wakatipu, from which " fragments of a jaw with long 

 slender Plesiosaurus-like teeth" were obtained §. In the Otago 

 Museum there is a fragment of an Ammonite from the Matakea 

 Series near Shag Point ||. Dr. Hector mentions Inoceramus and 

 Belemnites from the Awanui Series in the East Cape District % ; and 

 Mr. Cox reports Inoceramus from the Wairoa river, Kaipara 

 Harbour **. A " smooth Inoceramus " is also mentioned bj Mr. 

 M^Kay as occurring in many places between East Cape and Cape 

 Palliser tf. 



No undoubted Mesozoic fossils have been reported from any other 

 of the districts considered by the Geological Survey as " Cretaceo- 

 tertiary." According to Dr. Hector " no trace of a Belemnite 

 j)03sessing the upper part of its guard or phragmocone has been 

 discovered in any bed above the black grit " J J, that is about the 

 middle of the Amuri Series. But, he says, smooth fusiform bodies, 

 with a minute depression or perforation at the lower end, which 

 exfoliate from the central portion of the guard of B. australis, have 

 been found at Green Island, near Dunedin, at Waitaki, and at 

 Mt. Hamilton in Otago. He further says that these bodies form 

 the Acanthocomax (? Actinocamax') of Miller, and have frequently 

 been mistaken for spines of Cidaris. But as no whole guard of a 

 Belemnite, even without the phragmocone, has as yet been found at 

 any of these localities, nor in any rock supposed to be of the same 

 age, the nature of this fossil must, for the present, be considered 

 doubtful. The rocks in which it occurs at Green Island and at the 

 "Waitaki, I consider, from other palseontological evidence, to belong 

 to the 0am aru System. This fossil is identical with the " pseudo- 

 belemnite " described by Dr. Mantell from what are known as the 

 " Hutchinson Quarry beds" at Oamarii§§, and which are considered 

 by the Geological Survey to be of Upper Eocene age. 



Oamaru System. 



In the NortJi Island this system occurs in many places north of 

 Auckland and all down the west coast from Port Waikato to Mokau
