between the subantarctic islands: Marion, Prince Edward, Crozet, Kerguelen,

of Terres Australes et Antarctiques Francaises, Paris, greatly increase our
knowledge of the brachiopoda of the Indian Ocean. Eighteen species are

Xenobrochus australis, X. anomalus; Dallithyris? dubia; Dyscolia? radiata, Platidia
marionensis; Ecnomiosa inexpectata, and Thecidellina minuta. Seven hitherto described
species are recorded: Pelagodiscus atlanticus (King); Pemphixina pyxidata
(Davidson); Liothyrella moseleyi (Davidson); Megerlina davidsoni (Velain); Megerlia
gigantea (Deshayes); Aerothyris kerguelenensis (Davidson), and A. aff. A. macquariensis
(Thomson). Six genera, which could not be identified specifically, were
also taken: Crania, Basiliola, Tegulorhynchia, Eucalathis, Liothyrella, and Aerothyris.
Genera recognized in the Indian Ocean for the first time are: Tegulorhynchia,
Basiliola, and Ecnomiosa, the last hitherto known only from the Gulf of Mexico
