Abstract
Laoma s.str., based on Laoma leimonias (Gray, 1850), also includes L. marina (Hutton, 1883), L. ordishi (Climo n. sp.), L. labyrinthica (Powell, 1948) and L. nerissa (Hutton, 1883), which is reinstated as a valid species. Recently collected material of these Laoma spp. from a wide spread of localities in New Zealand shows that reabsorption of apertural lamellae during growth does not change their configuration in the manner proposed by Suter (1891: 283–285). All species discussed here are endemic to New Zealand. They overlap tightly in their distribution but are often allopatric at local scale, around Auckland–Waitemata–Hauraki Gulf, North Island, while elsewhere they are geographically well-separated. The naturally uncommon L. labyrinthica (Three Kings Islands) is the only species of conservation concern in this group.

Thomas Frederick Cheeseman, Auckland Museum’s curator from 1874 to 1923, was a careful and meticulous administrator who kept a detailed record of his activities. In this report we summarise the extent and organisation of the Cheeseman papers held at Auckland Museum. There are at least 3500 pages of outgoing correspondence, addressed to around 800 different people and organisations, and we provide a preliminary alphabetical index to these correspondents. The Cheeseman papers form a rich and useful legacy for an understanding of museology and the history of science—and social history in general—both for Auckland and for New Zealand.
Read moreHenry Ward, of Ward’s Natural Science Establishment, Rochester, N.Y., U.S.A., visited Auckland in March 1881 (and again in November 1896) where he met Thomas Cheeseman, curator of Auckland Museum. The two men formed a professional friendship and corresponded for 27 years. During this time they arranged a series of exchanges of natural history specimens, despite Auckland Museum being only a minor customer of Ward’s because it had little material to exchange and small budgets for purchase. From Cheeseman, Ward obtained bird specimens (especially kiwi Apteryx), ethnographic items, kauri gum and volumes of Transactions of the New Zealand Institute. Ward sent Cheeseman casts of ‘celebrated fossils’ and of the Rosetta Stone, articulated skeletons of a human and an ostrich, Blaschka glass models, mineral specimens, a lungfish and a giant salamander.
Read moreThe Marine Department of Auckland War Memorial Museum has an actively growing type collection with over 1770 primary types and a further 1836 paratypes and paralectotypes. The majority are molluscan, and this third part of a catalogue of these collections reviews the types for 12 Patellogastropoda and 184 Vetigastropoda species and subspecies. It deals with 130 primary types and 142 secondary type lots, which are split between 140 Recent taxa and 56 fossil taxa. Eleven of the holotypes reviewed here are illustrated for the first time.
