Further Tertiary Mollusca from Hokianga District, North Auckland. By C. R. Laws, University. College, Auckland. [Read before Auckland Branch, December 6, 1946; received by Editor, January 16, 1947; issued separately, April, 1948.] In a previous paper (Trans. Roy. Soc. N.Z., Vol. 76, 1947, pp. 537–40), the writer recorded and described certain fossils from beds in the Hokianga district; but recent collecting, mainly in the vicinity of Waimamaku, has led to considerable increase in the number of species known from these beds. The majority of the new forms are small species that have been obtained by sieving matrix collected from small lenses and strings containing broken shelly material. There is little doubt that systematic search at further outcrops will yield results that will considerably increase the number of tiny molluscs, constituting the fauna of these beds. The localities where the recent collections were made are for convenience designated by letters, as follows:— A. Hokianga South Head. A low outcrop at top of beach below the house of the keeper of the signal station. B. Hokianga South Head. An outcrop constituting a wave-cut platform two or three chains nearer the Head than A. C. Taita Stream, twenty chains above its junction with Oraora Stream. D. Taita Stream, approximately thirty chains above its junction with Waimamaku River. E. Waimamaku River, approximately twenty-five chains below its junction with Taita Stream. F. Low cliffs along bed of creek draining from the north into Waimamaku River, one mile north-west of Waimamaku Post Office. Faunal List. (P indicates Pakauiangi Point beds, Kaipara Harbour.)
