This paper reports on an orphaned collection of echinoderms housed at the Durban Natural Science Museum, South Africa. The collection includes holotypes of the South African endemic ophiuroid Asteroschema capensis Mortensen, 1925 [=Asteromorpha capensis (Mortensen, 1925)] according to Okanishi et al. (2013) and the South African endemic asteroid Anthenoides marleyi Mortensen, 1925. The holotype of the asteroid Hacelia superba var. capensis Mortensen, 1925 has not been found and is considered lost, whilst the holotype of Anthosticte pacei Mortensen, 1925 [=Tethyaster pacei (Mortensen, 1925)] is reported to be housed in the Zoological Museum Copenhagen, Denmark. The collection includes both wet and dry specimens of extant Asteroidea, Ophiuroidea, Echinoidea and Holothuroidea with Crinoidea being absent. Holothuroidea were excluded from examinations due to lack of locality data. In addition, Plococidaris verticillata (de Lamarck, 1816) is a new distribution record for South Africa. This paper gives new accession numbers of the specimens and the only photographic record of this collection.
