REPORT ON THE POLYZOA. 
81 
(4) Bifaxarici papillata, n. sp. (PL XIII. fig. 4, and PL XXIV. fig. 4). 
Character. — Zoarium branched bifariously, branches opposite, curved, ascending, 
with short secondary branches. Zooecia urceolate, square in front with a slight mesial 
keel and a ridge on each side, all three terminating at the anterior border of the orifice 
in small spinous processes. Anterior wall entire ; two rows of distant punctures on the 
sides, one of three or four small ones close to the border, and the other of as many larger 
ones down the middle of the side. Oral angular avicularia very minute and often absent 
altogether. On the older zooecia a papilliform avicularium with an elliptical or sub- 
triangular mandible. Ooecia deeply immersed, often with a very large conical eminence 
on both sides, on the under side of which is an avicularium with an elliptical mandible. 
Habitat. — Station 196, lat. 0° 48' S., long. 126° 58' E., 825 fathoms, hard ground. 
Having much the same habit as Bifaxarici corrugcita, the present differs from that 
form, — 1. In its much smaller size ; 2. In having the branches curved instead of straight ; 
3. In the branches being opposite, and also in that the primary give off secondary branches ; 
and 4. In the shape of the zocecium, which is flattened or square in front and imperforate, 
though with punctures on the sides. In the older cells one of these punctures appears 
to become elevated into a papilliform avicularium, which in some cases attains an enor- 
mous development on the sides of the ooecia and sometimes on one of the ordinary zooecia 
(PL XXIV. fig. 4 cl). 
The lateral puncta are concealed under the epitheca and were overlooked when the 
drawing was made (Pl. XIII. fig. 4). 
(5) Bifaxarici minuta, n. sp. (PL XIII. fig. 5). 
Character. — Zoarium very small (probably) ; zooecia fusiform ; orifice semicircular ; 
a circular immersed avicularium on each side close to the orifice. A thin ridge down 
each side towards the front and a septal ridge between the two series of zooecia ; five or 
six small punctures close to the septal ridge. 
Habitat. — Station 70, lat. 38° 25' N., long. 35° 50' W., 1675 fathoms, Globi- 
gerina ooze. 
The only specimen in the collection is a very small fragment, including the lower 
part of the zoarium and the bundle of radical fibres by which it was affixed to Globi- 
gerina shells. The state of the specimen does not afford any clue to the habit of the 
growth, but it was doubtless of only small size.
