genus Trigonia. There is, however, at Brighton, twelve miles south of 

 Dunedin, a pebbly, hard shell-bed containing a belemnite, which rests almost 

 directly on the coal. This shell-bed has been classified by Hector, Hutton, 

 Park, and others as of Tertiary age. The belemnite has not yet been 

 accurately classified. Hector called it Belemnites lindsayi, though he after- 

 wards suggested that it might be classed with Acanthocamax (Actinocamax) 

 of Miller. Specimens sent by me to Otto Wilckens, of Jena, were submitted 

 to specialists in Europe, who stated that they were too much rolled for 

 accurate description, but they were certainly specimens of a true belemnite. 

 The two Trigoniae and this belemnite are the only Cretaceous types hitherto 

 admitted to occur in Tertiary rocks in New Zealand. It is, however, true 

 that the collections of Tertiary fossils have been almost entirely made from 

 the upper beds, as the lower are generally quite destitute of fossils. 



{v.) Wangaloa. 



In those localities where these lower beds are fossiliferous very small 

 collections have been made. One of these localities is Wangaloa, situated 

 on the east coast, about seven miles to the north of the mouth of the Clutha 

 Eiver. These beds were first classed by Hector in 1872 as Upper Tertiary. 

 Hutton in 1875 classed them as Pareora (Miocene). In 1910* Suter de- 

 scribed a fossil from this bed as Turritella semiconcava. He states that 

 Park, from whom the fossil came, has classed the bed as Cretaceous because 

 of the occurrence of Conchothyra, Belemnites, and Aporrhais. Park, in the 

 " Geology of New Zealand," 1910, classes the Kaitangata coal-measures, in 

 which the Wangaloa beds occur, as Cretaceous. Hector referred to them 

 more fully in the Geological Survey Eeports, 1890-91, p. Iviii, and placed 

 them in his Cretaceo-tertiary as a lower horizon than the Ototara stone. 



No lists of species have yet been recorded from this locality. The one 

 given here does not pretend to completeness, though some two days were 

 spent in collecting. The fossils occur in concretionary masses in a cal- 

 careous sandstone with some glauconite. These concretionary masses often 

 unite and form a continuous stratum in the quartz grits. There is a general 

 agreement that the horizon is a little higher than the Kaitangata coal. 



In the collections that were made the following fifty-two species were 

 found. They have been classified by Mr. H. Suter, to whom I am deeply 

 indebted, for without his aid the precision of the identifications would be 

 much less complete, and the lists would have a much smaller value. I give 

 the list as I received it from Mr. Suter : —
