(1) Supercytis digitata, d’Orbigny (PI. V. fig. 3). 
Supercytis digitata, d’Orb., Palseont. Frang., p. 1061, pi. dccxcviii. figs. 6-9 ; Waters, loc. tit., 
p. 692, pL xxxi. figs. 22, 26, 27. 
Fasticulipora digitata, Bk., loc. tit., p. 37, pi. xxxiii. fig. 1. 
Character. — Zoarium oblong, (PI 2 x 0'8 mm.; the stipitate capitulum flattened above, 
presents a large central area covered with a hexagonally areolated lamina, and from 
the sides project twelve digitate, forked, or sometimes trifid compressed lobes, composed 
of longer or shorter tubular zooecia, about (P2 mm. in diameter, almost completely 
immersed or sometimes slightly projecting, and opening throughout the whole length 
of the lobe on its upper flattened aspect, and some from the areolse of the central 
area. Dorsal aspect of the lobes rounded, even, longitudinally striated and minutely 
punctate. Ocecia ? 
Habitat. — Station 167, lat. 39° 32' S., long. 171° 48' E., 150 fathoms, blue mud. 
[Cape Capricorn, Australia, H.M.S. “Rattlesnake.” Fossil, Cretaceous, Meudon, &c., 
d’Orbigny ; South Australia, Waters.] 
(2) Supercytis tubigera, n. sp. (1) (PI. Y. fig. 4). 
Character. — Zoarium stipitate, capitulate; capitulum irregular or inequilateral; 
central area small, not areolated, but covered with a thickish calcareous lamina, with 
concentric rugae, giving it a conchoidal aspect ; ten or twelve marginal fasciculate or 
digitate bi- or trifurcate compressed processes, in which the zooecia are disposed more or 
less regularly in series of connate tubes, opening either at the extremity of the fasciculus 
or on its upper flattened aspect ; at the base of some of the fasciculi a few much 
elongated tubular zooecia arise nearly vertically, with punctate walls, and about 0'25 mm. 
in diameter. Dorsal surface of fasciculi and capitulum striated and minutely punctate. 
Ooecia in the form of hemispherical projections at the base of the lateral fasciculi and 
usually on the upper aspect. 
Habitat. — Station 151, off Heard Island, 75 fathoms, volcanic mud. 
As the collection affords only a single specimen, which conveys the impression of a 
somewhat distorted growth, it may, perhaps, be merely a variety of the preceding. But 
the absence of areolation of the central area of the capitulum and the presence of the 
much elongated tubular zooecia, together with the occurrence of the hemispherical ocecia, 
appeared to me to justify its being considered specifically distinct.
