WELLINGTON : PRINTED AT THE OFFICE OF JAMES HUGHES, LAMBTON QUAY, 1880. — P K E F A C E An accurate knowledge of the affinities and distribution of the recent Shells of New Zealand is a very necessary element in the Geological Survey of the country, as it must form the basis of our Tertiary Geology, upon the correct decyphering of which many questions of the highest interest depend ; such, for instance, as the former distribution of land, of ocean currents, and of temperature in the Southern Hemisphere, and the true nature of the agencies which have operated in producing the Auriferous alluvia or Gold Drifts. Shells afford the most reliable data for Palaeontologists ; but before the extinct shell fauna can be utilized, the recent shells of the area must be thoroughly determined. The preparation of the first Catalogue was beset with difficulties, which were explained in the preface to that work ; but, as was then anticipated, its publication has led to a vast im- provement in our knowledge of the subject. The consent of Government was, therefore, readily given to the printing of the present work at the public expense, the compilation of which has been an entirely gratuitous service on the part of Professor Hutton. This Manual is not, however, merely a new edition of the Catalogue by the same Author which was issued by this Department in 1873, but it embodies and replaces the following works, all of which are now out of print : 1. Catalogue of the Marine Mollusca of New Zealand. By F. W. Hutton. Wellington, 1873. 2. Critical List of the Mollusca of New Zealand. By Ed. Von Martens. Wellington, 1873, 3- Catalogue of the Land Sliclls of New Zealand. By J. C. Cox, M.D., F.L.S. (of Sydney.) Wellington 1873- The information contained in these works, together with much that is new, is now presented in a convenient form for reference, and it is hoped that the present Manual will be of service to teachers of Natural History as a text book in a department of New Zealand Zoology that is particularly adapted for training students in the art of collecting and classifying natural objects.
