taining two zones of fossils about 20 fc. apart, the 

 lower 6 ft. thick and the upper 3 ft. thick. 



(d.) Bed of pebbly conglomerate and sandstone varying 

 from 3 ft. to 6 ft. thick, and separated from the 

 upper fossiliferous zone by several feet of flaggy 

 claystone. 



{e.) Gvej indurated sandstones, and flaggy claystones. 



Fossils are very abundant in the two lower zones, and, 

 although many are flattened and deformed through the altera- 

 tion which the rocks have suffered, distinct and well-preserved 

 casts are numerous, and easily broken out. 



Among the genera identified in a small collection were 

 Spirifera (two sp.), Spiriferina (two sp.), Athyris, Epithyris, 

 Bhynchonella, Edmondia{7), Allerlsma('?), Schizodus, Ostrea, 

 Turbo, Patella, Pleura tomaria, and a nautiloid shell. 



Captain Hutton examined the collection in Dunedin, and 

 subsequently, after looking over the Permo-carboniferous 

 fossils of New South Wales in the Canterbury Museum, in- 

 formed me that he was pretty sure the Mount Mary collec- 

 tion included Sjniifera vespertilio, G. Sow., Sptrifera sub- 

 radiata, Sow., Eurydesnia, Morris, and Platychisma — forms 

 characteristic of the Permo-carboniferous of New South 

 Wales.- 



Mr. W. S. Dun, of Sydney Museum, to whom a small 

 collection of these fossils was sent, in a letter to Mr. A. 

 Hamilton confirmed the identification of the spirifers made 

 by Captain Hutton. 



A collection of these fossils is now in the hands of Pro- 

 fessor Boehm, of Frieburg, for identification and description. 

 His determinations will be awaited with much interest by 

 students of New Zealand geology. 



Subdivision and Cokrelation. 



The grey phyllites, banded quartzites, aphanitic sand- 

 stones, and greywacke at the base of the succession com- 

 prise the " Kurow schists " of McKay, which were rightly 

 referred by that geologist to the Kakaiiui series of Hector. 

 It has generally been admitted that tlie Kakanui series of 

 Hector is the equivalent of the Kakanui (Tuamarina) for- 

 mation of Huttonf and the Waihao formation of Haast.| 



The rocks forming the upper part of the succession cor- 

 respond closely to the description given of the Kaikoura 

 formation of Hutton§ and tlie Te Anau series of Hector,
