Gobholo Cave Expedition 2014. Before the expedition to Gobholo Cave in Swaziland, we spent some time on sightseeing and safari in South Africa. We flew in to Johannesburg, rental cars to Hluhluwe where we stayed two nights in Isinkwe Backpackers Bushcamp. From there we travelled to the Indian Ocean and St Lucia for two more nights, and, for the new year eve, somewhat further south to Richard Bays for the last three nights before travelling in to Swaziland and Kopola Estate in the Ezulwini valley near Mbabane. Expedition members, from Sweden: Manuela, Peter, Rabbe, Ljuba and Johannes, from Austria: Pauline, Harald and Thomas (plus non-caver Christa), for the expedition week, from South Africa: Sharron, Edward, Daneel and Leon, and from Swaziland: Darron. Gobholo Cave is now the eight longest granite cave in the world, explored to a length of 1.1 km, but the exploration continues (follow future expeditions on gobholocave.org)! Many thanks to Swazi Trails (www.swazitrails.co.sz, in particular Anita and Darron) for much invaluable support!

The Neotaenioglossa is an taxonomic name for a large group of mostly sea snails. The name was originally created by Haller in 1882. Ponder and Warén (1988), and Marquet (1997), assigned this name to the superorder Caenogastropoda. ITIS considers the order Neotaenioglossa to be a synonym of Cerithioidea Férussac, 1819 .
