Exhibits.—The Director exhibited and described the following specimens recently collected by members of the Geological staff:—

– 440 –
(1.)

A large block of sandstone from Te Paretie Creek, Mohaka River, covered with a large and beautiful form of the genus Flabellum, probably a new species from the higher beds of Lower Miocene formation. A number of other fossils occur in the same block, among which is Aturia. ziczac. These were collected by Mr. McKay.

(2.)

A remarkable fossil shell from lower green-sand formation in the East Cape District (Awanui Series), collected by Mr. McKay, probably belonging to the genus Margaritana, allied to the freshwater pearl-shell of Britain. The characters of this fossil were described, and the relation of the beds from which it was obtained showed that this fossil would be of considerable value in assisting the recognition in the field of the horizon in the Lower Cretaceous rocks that yield bituminous shale and petroleum oil.

(3.)

Specimens of a large fossil stalked Cirripede, recently collected by Mr. Park, at Motatapu Island, Auckland. A careful restoration will have to be made before definitely determining this fossil, but it will probably be found to belong to the genus Scalpellum, and is distinguished provisionally under the name of S. aucklandicum. In size, this fossil Cirripede greatly exceeds any previously known, in S. magnum the capitulum being only 1 ½ inches in length, while in the Auckland specimen it is at least 8 inches. These fossils occur in a breccia, marking the old shore line of the upper part of the Waitemata Series, similar to the Cape Rodney beds. The associated fossils are Corals, Brachiopods, and Echinoderms. Among the latter are two specimens having plates of a Cidaris of enormous size.
