Family NUCLEOCORBULIDAE Santhakumari & Nair, 1970

Large, cylindrical, with spiraled rows of somatic ciliature running nearly at right angles to long axis of body; prominent aboral sucker or adhesive disc; buccal ciliature appears to be at posterior pole; huge, branching macronucleus; in mantle caviry of shipworm (eulamellibranch mollusc).

[The organism was possibly figured upsidedown; it seems to possess several important hemispeirid characteristics and may not deserve separate familial standing.]
