Revision of the Tertiary Mollusca. of New Zealand, based on 

 Type-material. Part I. By Henry Suter. Palseontological 

 Bulletin, No. 2, New Zealand Geological Survey (P. C. Morgan, 

 Director). 4to ; pp. 64, pis. i-xvii, with a transmittal letter by 

 P. G. Morgan' and a preface by J. Allan Thomson. Wellington,

11HE authorities of the New Zealand Geological Survey are to be 

 congratulated on having secured the services of so well known 

 a conchologist as Mr. Henry Suter, member of the Malacological 

 Society of London, to undertake the revision of their Tertiary 

 Mollusca from that country. His long experience as a student and 

 a writer of the living shells of New Zealand has specially fitted him 

 to accomplish so important and necessary a task. 



As a first fasciculus in this direction the present memoir deals 

 entirely with the type-material which formed the basis of the late 

 Captain F. "W. Hutton's Catalogue of the Tertiary Mollusca and 

 Echinodermata of JVew Zealand in the Collectmi of the Colonial Museum, 

 published in 1873, a revision of which has been long required from 

 the fact that it iucluded a number of brief diagnoses of new species 

 without the support of illustrations, although certain "lithographed 

 plates " were promised to be " issued shortly " in a preface written to 

 the work by the late Sir James Hector, which, however, were never 

 forthcoming. Some of these new species were subsequently figured 

 by Hutton in his monograph on The Pliocene Mollusca of New Zealand, 

 which formed part of " The Macleay Memorial Volume ", issued under 

 the auspices of the Linnean Society of New South Wales in 1893. 

 Since that date palaeontologists have been mainly indebted for any 

 further knowledge of the subject to the writings of the late Mr. G. F. 

 Harris, whose excellent treatise on The Australasian Tertiary Mollusca 

 in the British Museum, published during 1897, included several 

 forms from New Zealand. In addition to such memoirs it must not 

 be forgotten that many species of New Zealand Tertiary Mollusca 

 had been previously described and figured by the late Professor von 

 Zittel in his Fossile Molluslcen und Echinodermen aus JYeu-Seeland, 

 forming vol. i of the " Novara Expedition " report of 1864. In this 

 connexion Zittel's researches Avere of peculiar geological interest 

 because, from a study of the palseontological works of G. B. Sowerby 

 and Alcide d'Orbigny on South America, he was able to trace 

 a resemblance between the Tertiary faunas of New Zealand and 

 those of Chili and Patagonia, the existence of such a relationship 

 having been strongly supported since by Dr. Ortmann and the later 

 specialists who met recently in Australia to discuss this and sundry 

 matters appertaining to the age of the Lower Tertiary rocks of 

 Australasia. 



A considerable reduction in the number of molluscan species has 

 been the outcome of this revision, Mr. Suter having recognized 

 101 species and varieties, consisting of 44 Gastropoda, 3 Scaphopoda, 

 and 54 Pelecypoda, as against Hutton's estimate of 275 species, made 

 up of 127 Gastropoda, 9 Scaphopoda, and 139 Pelecypoda — a result
