Abstract
Xenophyophores, large deep-sea rhizopodan protists, are very rare in A ntarctic seas. One specimen of Reticulammina antarctica nov. spec. was retrieved from bathyal depths in the Weddell Sea and preserved in a c omparatively good condition, thus allowing a cytological description. Faecal pellets (stercomata) enclosed within the test were found to con sist primarily of mineral particles. The hypothesis is offered that nu tritional nitrogen compounds adsorbed by clay minerals can be extracte d by these deep-sea rhizopods.
