Abstract

Three species of starfish, Anasterias directa (Koehler), Anasterias mawsoni (Koehler), and Cycethra macquariensis Koehler, and one species of holothuroid, Pseudopsolus macquariensis (Dendy) were collected over a period of one year from rocky sub-littoral shores at Macquarie Island. Study of preserved collections showed that both Anasterias species and the holothuroid have a brooding mode of reproduction and distinct reproductive cycles. For Cycethra macquariensis no cyclic reproductive pattern was evident. Ovarian condition in Cycethra macquariensis suggested a non-pelagic development; however the mode of this development was not observed. In addition, examination of some specimens of Pseudocnus laevigatus (Verrill), Trachythyone macphersonae Pawson (holothuroids) and Pseudechinus novaezealandiae (Mortensen) (echinoid) showed a brooding habit in Pseudocnus and ovarian conditions that suggested non-pelagic larval development for Trachythyone and pelagic larval development for Pseudechinus.
