Structure of the Ascidian Octacnemus Moseley

Abstract

THE tunicate family Octacnemidae contains two genera, Octacnemus Moseley and Polyoctacnemus Ihle, and four species, all from great oceanic depths. The species have been described by Moseley1, Herdman2, Metcalf3, Ritter4, and Madsen5; but their structure is peculiar and has never been satisfactorily related to that of other tunicates.
