REPORT ON THE POLYZOA. 29 



(1) Supercytis digitata, d'Orbigny (PI. V. fig. 3). 



Supercyils digitata, d'Orb., Palaeont. Frang., p. 1061, pL dccxcviii. figs. 6-9; Waters, loc. eit., 



p. 692, pL xxxi. figs. 22, 26, 27. 

 Fasciculipora digitata, Bk., loc. cit., p. 37, pi. xxxiii. fig. 1. 



Character. — Zoarium oblong, 0'12 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 0"2 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 areolae of the central 

 area. Dorsal aspect of the lobes rounded, even, longitudinally striated and minutely 

 punctate. Ooecia ? 



Habitat.— 8ta.tion 167, lat. 39° 32' S., long. 171° 48' E., 150 fathoms, blue mud.

(2) Supercytis tuhigera, n, sp. (?) (PI. V. fig. 4). 



Cliaracter. — Zoarium stipitate, capitulate; capitulum irregular or inequilateral; 

 central area small, not areolated, but covered with a thickish calcareous lamina, with 

 concentric rugse, 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 aflFords 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 ooecia, 

 appeared to me to justify its being considered specifically distinct.
