The German geographer Voeltzkow, although he only spent something over a month on Aldabra during April to May 1895, made the first known collection of Entomostraca from the atoll. His lively account includes mention of four species of Ostracoda and also records the occurrence of daphnid cladocerans (Voeltzkow 1897, p. 67; English translation p. 21). Voeltzkow’s collection was described by G. W. Muller, who added another ostracode, a
Centrocypris
species which he did not describe because of scanty material, to Voeltzkow’s list (Muller 1898, pp. 275- 283). Ostracodes and cladocerans were also recorded by the Bristol University expeditions of 1964 and 1965 but not collected (R. Gaymer, personal communication 1967). The next additions to the known fauna were made by G. A. Wright of the British Museum (Natural History) who cultured ostracodes, an anostracan,
Streptocephalus
sp. and the conchostracan,
Eulimnadia
sp., from mud samples obtained during a September 1966 reconnaissance visit (Stoddart & Wright 1967, p. 1175). Further collections of dried mud from Aldabra were made by J. F. Peake of the British Museum (Natural History) during phase I (August to September 1967) of the Royal Society Expedition to Aldabra. One of these, from a pool between Croix Blanc and Anse Cèdres (the locality of sample 8, see appendix A) has been cultured since 5 December 1967 (see §8 (
d
)).
