The New Zealand graptolites which are dealt with in this paper were collected by Mr. E. Douglas Isaacson, mining engineer, New Zealand, for the British Museum (Natural History), South Kensington. Dr. A. Smith Woodward, F.R.S., very kindly gave me the opportunity of examining this interesting collection, which was sent to me in the Autumn of 1907. Shortly after its receipt Dr. Woodward forwarded me a copy of the New Zealand Geological Survey publication entitled “The Geology of the Parapara Subdivision, Karamea, Nelson,” by James Mackintosh Bell, Director, 1907, which contains brief descriptions and figures of graptolites collected from the same locality as that from which Mr. Isaacson collected his specimens. Since, however, the records of graptolites from New Zealand are very limited in number, and since Mr. Isaacson's collection contains a greater variety of forms than that of any previous observer, it seems advisable to publish the identifications that I have found it possible to make from an examination of his collection.
