The collection was donated to the Natural History Museum (NHM) between 2009 and 2011 and consists of 2534 slides. It comprises mainly marine ostracods of Jurassic to Holocene age from southern Africa (and its adjacent oceans), Antarctica and New Zealand. There is also a small collection of Quaternary non-marine ostracods from southwestern Africa, two sets of DSDP/ODP ostracods from the Southern Ocean, and one set of Cape Roberts Drilling Project (CRDP) ostracods from Victoria Land, East Antarctica. The individual slides in this collection have been computer registered. Further details of these can be found by inputting seach criteria based on information given in the paper to the NHM’s on-line catalogue at http://www.nhm.ac.uk/research-curation/collections/departmental-collections/palaeontology-collections/search/index.php.
