CAPT. F. W. HTJTTON" OIH THE 



be separated from the Wairoa Series. The only characteristic fossil 

 mentioned by Dr. Hector is Trigonotreta undidata. Labyrinthodont 

 teeth and Glossopteris are found both here and in the next higher 

 series. Remains of what appears to be an Ichthyosaurus * have 

 been found near Mt. Potts, in S. Canterbury, in beds recognized by 

 the Geological Survey as belonging to the Kaihiku Series. Dr. 

 Hector considers this series of Permian age ; at the same time he 

 notices the absence of " the usual Palaeozoic elements of a Permian 

 fauna, " and, I may add, of a Permian flora also. 



The Wairoa Series is well characterized by the following : — 



Belemnites (?) otapiriensis, Hector. 

 Monotis salmaria, var. richmondiana, 

 ZiUel. 



Halobia Lommelli, Wissm. 

 Mytilus problematicus, Zittel. 

 Spirigera Wreyi, Suess. 



There are also several Spirifers which are referred by Dr. Hector 

 to new genera or subgenera (not yet described) called Glavigera, 

 Rastelligera, and Psioidea f. 



Among the plants are Dammara fossilis (Ung.), Zamites, RTiacho- 

 phyllum, Glossopteris, and Neuropteris. 



The Mataura Series is characterized by 



Ammonites noyo-zelaxidicus, Hauer. 

 Belemnites aucklandicus, Hauer. 

 Hochstetteri, Hector \. 



Belemnites catlinensis, Hector. 

 Inoceramiis Haasti, Hochst. 

 Aucella plicata, Zittel. 



The plants are Poly podium Hochstetteri., Uiig-? Asplenium palce- 

 opteris, Ung., Tceniopteris linearis, and Macrotceniopteris lata §. 



Waipara System. 



In the South Island this system extends, with a few interruptions, 

 from Cape Campbell in Cook's Straits to the river Ashburton in 

 S. Canterbury (Amuri Series), and an isolated patch occurs in the 

 Trelissick basin on the upper Waimakariri. In Otago it includes 

 the coal-measures of Shag-point and the Horse Range (Matakea 

 Series), as also the coal of Mt. Hamilton and possibly a small patch 

 on the north shore of Lake "Wakatipu. In the iN'elson Province it 

 includes the coal-measures of Pakawau, and the bituminous coals 

 of the BuUer and Greymouth. In the North Island Mr. M'^Kay 

 has recognized the system on the east coast of Wellington ||, and it 

 apparently covers a large extent of country in the Waiapu district, 

 in which oil-springs are situated (Awanui Series) ; and again on 

 the Wairoa river north of Kaipara Harbour % in Auckland. But

 toraaria. ornata, and Tancredia truncata.

 Cycadites, Echinostrohus, and Camptopteris.
