INTRODUCTION. 



lu addition to the above, the following belong to the Pareora formation, but it 

 is uncertain in which group they should be placed : — 



Xorth Island : Upper Wanganui River ; Hautapu Tails, Upper Rangitikei ; 



iManawatu Grorge (upper end) ; White Cliffs, Taranaki. 

 South Island : Conway Eiver ; Kokohu ; Pareora ; Waitaki ; Weka 

 Pass (r). 



Ahuriri formation. — North Island : Napier ; Castle Point ; Taipo, on the 

 East Coast of Wellington ; Kawau ; Cape Eodney ; Orakei Bay, Auck- 

 land (?) ; Waitotara. South Island : Broken River * (r) ; Hurunui 

 Mound ; Te Anau Lake (?) . 



Trelissich group. — South Island : Broken River* (l) ; Weka Pass ; 

 Mount Brown ; Deans, Waipara ; Kaipuki Cliffs ; Point Elizabeth ; Tata 

 Island. 



Ototara group. — North Island : Poverty Bay (l) ; Raglan ; Port Waikato ; 

 Aotea ; Wangape Lake ; Wangarei ; Cape Kidnappers. South Island :. 

 Cobden ; Weka Pass (l) ; Waipara (l) ; Oamaru ; Caversham ; Curi- 

 osity Shop ; Brighton ; Waihola Grorge. 

 In addition to the above, the following also belong to the Oamaru formation, 

 but the evidence is not yet sufficient to say in which group they should be placed : — 

 South Island : Culverden ; Black-birch Creek ; Pahau ; Cape Farewell ; 

 Takaka ; Lake Wakatipuf ; Cave Creek, Mount Somers ; Tokomairiro ; 

 Winton. 



In addition to the above, beds of Pleistocene (Post-pliocene) age are found at 

 Wanganui, Motanau, and Cape Kidnappers. 



The fossils from the Chatham Islands appear to be mixed, as shells characteristic 

 of the Kaniei'i group, the Ahuriri formation, and the Trelissick group are all in the 

 collection. I think it probable that two formations occur there, one belonging to 

 the Pareora formation, and the other intermediate between the Ahui'iri and Oamaru 

 formations. If, however, there should be only one formation present, I should be 

 inclined to refer it to the Ahuriri period. 



In the following pages, when more than one iertianj formation occurs in a 

 locahty, I have marked the upper, middle, and lower formations by the letters (u), 

 (m), and (l) respectively, immediately after the name of the locality. I have also 

 included in the Catalogue descriptions of a few species taken to Europe by Dr. 

 Hochstetter, but not represented in the collection of the Colonial Museum ; these 

 species will be found pointed out in the text.

*Same locality as Trelissick of previous lists. — J.H. 



t The limestones of Lake Wakatipii may perhaps belong to the Upper Cretaceous period 

 (Waipara formation), as the fossils are not very characteristic, and considerably distorted.
