Le coeur se situe en grande partie posté- rieurement à la boucle intestinale, surtout chez les zoïdes femelles.

L’incubation des larves dans la région oesophagienne de l’abdomen est également un caractère particulier.La consistance très molle des colonies et la répartition du pigment foncé dans la couche supérieure de la tunique seulement, devraient permettre de reconnaître plus facilement cette espèce.

La base est entièrement incrustée de sable mais la partie superficielle en est dépourvue et a une coloration bleu-noir qui persiste dans le formol. La tunique contient de nombreuses pelotes fécales dans toute son épaisseur. Les zoïdes sont incolores mais la tunique à leur contact contient d’abondantes cellules rondes foncées. Les zoïdes forment des systèmes étoilés en surface des colonies. Les orifices cloacaux sont groupés mais sans dépression centrale. Le siphon cloacal est plus long que le siphon buccal. Le thorax est long, le nombre de stigmates n’a pas pu être compté, le premier rang est relevé dorsalement. La musculature thoracique constituée de fibres longitudinales et transverses entrecroisées est très forte. Le tube digestif a les segments habituels, le rectum se courbe au-dessus de l’estomac par contraction seulement. La glande pylorique s’étend en tubules longitudinaux parallèles. Les gonades sont logées dans la boucle digestive avec de nombreux lobules testiculaires et un gros ovocyte central. Des cellules contenant un matériel cristallin sont présentes dans le manteau au niveau de l’abdomen.</paragraph>
