Material examined . MD 50 DC108, MNHN IE .2009.1618 (2). Distribution . W Indian Ocean ( 250 m ). SPA ( 460–510 m ). Remarks . These tiny specimens (1.0– 1.3 mm dd) are referred to Ophiophycis gloriensis from the SW Indian Ocean as they have a first LAP that extends to the disc margin, spiniform thorny arm spines, a star-shaped centrodorsal plate and 4 visible pairs of tentacle pores. They differ from the larger type ( 2.5 mm dd) in having only one tentacle scale and one scale between the radial shields. These are distinguishing features of another species from St Helena, O. gracilis Mortensen, 1933d , which Litvinova (1981) considers a juvenile of Ophiomisidium speciosum Koehler, 1914 . Ophiomisidium speciosum has also been reported from Kerguelen ( Guille 1982 ), south of the SPA. More data is required to resolve the relationship of Ophiophycis and Ophiomisidium species.
