REPORT ON THE POLYZOA.

(24) Cellepora bilcibiata, n. sp. % (PL XXX. fig. 2). 
Character. — Zoarium pisiform, very minute. Zooecia very irregularly disposed 
erect, pitcher-shaped. Mouth circular, emarginate (fig. 2a) ; peristome thick and often 
produced into a rather deep, bilabiate cup (fig. 2b). In some zooecia, a short strong, conical 
pre-oral process. Ooecia (fig. 2c) small, spherical, recumbent. 
Habitat. — Station 161, off Port Philip, 33 fathoms, sand (parasitic on Amathea 
spiralis). 
The collection affords only one or two small specimens scarcely sufficient for the 
purpose of diagnosis. 
(25) Cellepora signata, n. sp. (PI. XXX. fig. 3, and PI. XXXYI. fig. 14). 
Chamcter. — Zoarium pisiform. Zooecia deeply immersed and very confusedly 
arranged ; surface smooth, shining. Orifice (fig. 3b) arcuate, with a straight lower lip, 
having a very minute median notch. A strong, curved, hollow pre-oral rostrum, with an 
avicularium on its posterior aspect near the summit, with a short, obtuse, spatulate 
mandible pointing upwards. A few large, interspersed avicularia (fig. 3d) with broad, 
spatulate mandible. Ooecium (fig. 3c) erect, flattened in front, on which is a semicircular 
area punctured (not grooved) round the border. 
Habitat. — Station 304, lat. 46° 53' S., long. 7 5° 11' W., 45 fathoms, sand (parasitic 
on a Sertularian). 
(26) Cellepora conica, n. sp. % (PL XX VIII. fig. 10, and Pl. XXXYI. fig. 1). 
1 Cellepora avicularis, Smitt, Florid. Bryoz. p. 53, pl. ix. figs. 193-197. 
Character. — Zoarium in small conical lobes ; 0"’ 125 to 0"*1 6 , disposed more or less 
in a stelliform manner. Zooecia with a slightly rugose surface, and in the very young ones 
obscurely punctured. Orifice clithridiate, peristome rather thick, sometimes raised on 
one or both sides. A cylindrical short curved pre-oral rostrum, with a terminal avicu- 
larium, with a semicircular mandible. A few interspersed retentive avicularia of small 
size, with spatulate mandible. Ooecia small spherical, deeply immersed, punctured all over. 
Habitat. — Simon’s Bay, Cape of Good Hope (parasitic on a Sertularian). 
I have little doubt that this is the young state of the form described by Prof- 
Smitt {loc. cit.) as Cellepora avicidaris, but I much doubt whether it is identical with the 
Cellepora avicularis of Hincks, which is of much larger growth, and consequently it is 
not the Cellepora avicularis, Smitt, as represented in specimens from Spitzbergen, which 
latter is Mr. Hincks’ species.
