34 DR. J. E. GRAY ON SOME NEW ZOOPHYTES. ([Feb. 11, 
and less contracted than the preceding ; the pores on the surface are 
more distinct, and are furnished with more or less dark polypes, 
which are all expanded. The polypes in one specimen (which 
is in the most perfect condition) are all entirely of a uniform black- 
brown colour. In one of the other specimens (also in a good con- 
dition) the polypes are pale brown, with a broad black lower ring 
at the upper part of the tubular body, near the base of the arms. 
In the other specimen (which is imperfect) the polypes are all pale 
brown, like the coral. 
In all the three specimens the polypes at the lower half of the 
club are further apart than they are at the tip; this is especially the 
case in the specimen which has the dark ring on the polypes, 
where the polypes in the lower part of the club are very far apart 
and few in number, and appear as if placed in longitudinal lines. 
I should propose to call this species provisionally Litwaria australis. 
5. Description or Two New Genera or Zoopuytes (SOuE- 
NOCAULON AND BELLONELLA) DISCOVERED ON THE NORTH 
Coast oF AusTratia BY Mr. Rayner. By Dr. JoHn 
Epwarp Gray, F.R.S., V.P.Z.S., F.L.S., erc. 
Among the numerous interesting animals collected by Mr. Rayner 
during the voyage of H. M.S. ‘ Herald’ is a new form of coral, nearly 
allied to Gorgonia, and especially to the coral called Calogorgia by 
M. Milne-Edwards, but very distinct from it. I therefore send a 
description of it to the Society for publication in the ‘ Proceedings.’ 
SOLENOCAULON. 
The coral coriaceous, tubular, circular, aud simple below, com- 
pressed, subquadrangular, tortuous, and more or less branched above, 
the branches being similar in size and form to the main 
stem. The main stem and branches furnished with 
more or less elongate, subsolid, slender branchlets, 
which are placed on the edge of the large holes in the 
main stem and branches which communicate with the 
main tube. These branchlets (and sometimes the 
branches at the base of them) are furnished with large 
cells for the polypes, which are placed in one (more fre- 
quently in two) series on each side of the branchlets, 
and sometimes the series are continued on the main stem 
or branches at the bottom of the branchlets. The polype-cells are 
rather large, circular, nearly superficial, and furnished with a cup 
divided into eight conical, connivent lobes, each lobe being formed of 
some transverse spicules at the base and some obliquely-placed spi- 
cules diverging from each lateral edge towards the top above.
