Andres, op. cit., p. 364. Stephanadis abyssicola Hertwig, op. cit., 1882. Plate XXII; Fig. 7(?) According to Moseley, in life its colour on the column was reddish j^ellow, paler on the parapet; capitulum rose-red, with darker radial lines; disk rose- red, tentacles paler red. Height was 5 mm.; greatest breadth, 35 mm. It was taken in lat. 40° 17' N., south of Nova Soctia, in 1,350 fathoms, in 1873. It probably should be called Raphactis abyssicola, for it agrees well with the type of that genus, in most respects. Perhaps my fig. 7, of pi. XXII, is the same species, from near the same region.

Two individuals surrounding and girdling a branch of Paragorgia (o, d,), and united by a suture above and below (a, b,); x about 1^. This small species has not yet been obtained in a sufficiently good state of preservation, for complete anatomical studies by sections; it has about 48 pairs of mesenteries; only six pairs are perfect; sphincter muscle mesoglceal, th
