Transactions and proceedings of the New Zealand Institute . les. It rests upon the metamor-phic rocks of the Kakanui series, and forms a line of boldsteep escarpment which presents many fine faces for criticalexamination. Perhaps the most interesting and importantpart of this long section is that exposed at the old BlackPoint Coal-mine, nearly opposite Borton Bailway - station,where the basement beds of the Tertiary series are veryclearly exposed. Stratigraphy. Mr. McKay ::: examined, and afterwards accurately de-scribed, the stratigraphy of this place in 1876. The numbersof the Tertiary series in descending order are as follows :— 1. Waitaki Stone, with 1a adhering to Glauconitic sandstone, fossiliferous. 2. Sandstones, often micaceous and gritty. 3. Busty-brown sands and sandstone, containing layers of hard calcareous nodules and lens-shaped masses. 4. Fireclays, carbonaceous shales, and brown coal. 5. Quartz and sandstone conglomerates, often limon- arrangement and relationships of these beds areshown in fig. 9. ITE. swr. TigS. Section at Black Point Coal-mine. 1. Waitaki Stone. 1a.

Mr. McKay mentions that he made a large collection offossils here, but does not give a list of the species. In hisfirst report on this place he states that he discovered severalgenera of Secondary cephalopods, including Aucyloccras andScaphites. In his later reports of the Waitaki Valley, in1876, 1881, and 1882, he ma
